audio set-up for beginners (ARCHIVED)

[batang_raon14]

[QUOTE=userfriendly;819585]Ano ba ang problem? Can you list your system? Does your amp cut off when you play at loud volume for a long time? If it does, your amp might be going into protect mode. This happens when your amp starts to overheat. Easy solution is to make sure your amps have good airflow. Make sure heatsinks are not dirty or blocked. Also never mount amps upsidedown. You can also add cooling fans or lower your volume.

If that is not the problem, try adding a capacitor. It will give your alternator time to catch up.

INMH, mas ok na magdadag na lang ng secondary battery than having a capacitor. passive component po yung cap, meaning, d sya nagsusuply ng power. unlike sa battery na active component, may nilalabas talaga syang kuryente.. this would compensate the power needed by your system pag d kaya ng alternator. one thing more, mas mura batt kesa cap os better have an extra batt over capacitor..

tama rin c userfriendly, baka nagooverheat amp mo.. san ba nakamount ung amp? try mo maglagay ng spacer between nung base ng ampli tsaka ung mounting surface. this way, may papasok na hangin sa base ng amp that will help to cool it down.. and try to mount it vertically para mas madali syang lumamig.

Mga bosing salamat sa reply, anyways, eto ung issue, not really familiar with the way an amp "cuts off".

While playing loud, after mga 45 mins., ung tunog anjan parin, pero parang sa likod na lang nanggagaling, wala na sa front speakers ko, tweeters, at ung bayo ng sub significantly humina. Maya-maya, after 10 mins. or so na i-off ung sounds, pagkaon mo balik na uli sa dati, pero after mga 45 mins. uli na malakas ang patugtog, ganun na naman.

Ung mounting ng amp ko is sa likod ng box ng sub. Bali nakaharap sya vertically sa rear seats ko, may around 2 inches allowance un from the back of the seats.

May capacitor na rin akong nakalagay, and setup ko e targa x652c (tama ba?) front, stock rear, aura sub, at v12 4 channel na class A(cant remember the model).

Tried scouting for the alternator kasi, wala talaga. Kahit sa mga online shops like ebay wala for my car. Kaya ako napatanong sa baterya, kung oks ba na magpalagay ako ng secondary or useless din at pagafter ng 45 minutes e gaganun din ung tunog?

Heto baka makatulong sa mga gustong mang upgrade ng stereo tunkol sa POWER AMP and SUBWOOFERS.

Ang two channel amps ay may dalawang outputs para sa dalawang speaker. Pero doesnt mean na pwede mong lagyang ng dalawang subwoofers. Para sigurado ka you just need to be aware of the impedance of your SUBS and the "load" capacity ng subwoofer mo. Sa ganitong sitwasyon, wiring method ay importante.

SERIES VS. PARALLEL WIRING

Ang typical na car stereo amps ay 4-ohm impedance. Pag sabi ang amplifier ay stable down to 2 ohms, usually referring to the minimum impedance na kaya niyang i handle sa stereo (2 channel) mode, hindi bridged (mono) mode. Kung mas mababa ang impedance(resistance or load) ng amplifier ay mas lalong mag po produces ng lakas at lalakas din ng tunog ng iyon tugtog.

A common way to get a 2-ohms stable amp para mag produce ng extra na lakas na kaya niyang ibigay is to wire your speaker in parallel. Basta tandaan mo na ang series wiring ay raises your impedance, parallel wiring is always lower.

Now, sa subwoofer box naman tayo.

Ang SUB box hindi basta, basta simply box lang na pwede mong ilagay ang iyong Subwoofer. Ito ay importante, it is an integral part of the system. A properly sized and built enclosure can turn your pinaka murang subwoofer into performer at tatawanan mo ang yong pinakamahal na subwoofer kung hindi tama ang box na gamit niya.

Dalawang klase ang pag design ng box at very challenging. siguraduhin mo ang tamang sukat para sa tamang volume of air and controlling the box resonances that will compete sa sounds na galing sa woofer and its sounds. Ang Ideal volume ng enclosure box ay depende kung anong subwoofer na gusto mo.
Ang enclousure volume ng box ay (length x width x height) at usually SUB quoted as INTERNAL VOLUME in calculating ang overall external dimension ng box. Importante ang thickness (5/8 or 3/4) at tigas ng tabla na gagamitin mo. Plywood ay hindi magandaang gamitin parang tunog ng latang
niyuyupi. Size ng box for 10 inch sub is 1 to 1.2 cu.ft.(WxHxL), 12 inch is 1.5 to 2.0 cu.ft. itoy single box lang. Kung dalawang sub na magkatabi sa iisang box then the cu.ft must double.

Remember good qualiy box is a must. Dont use nail on the box, use wood glue and wood screw on all joints and make sure the enclosure is airtight so seal all seams silicon caulking including around the terminal cup.

sir userfriendly... wg nmn un tipong png car show... typical boom boom lng :P hehehe... sabihin n ntin.. mga ave type po..

[userfriendly]

Batang raon,

From your description, it looks like your amp is overheating and going into protection mode. When you turn it off for around 10 mins or so, you give the amp enough time to cool down. After using it again for 45 min, the heat build up is enough to trigger protection mode. Yung V12 mo, orig ba o taiwan? And sure ka ba na class A and not AB? Kasi ang pure class a amps ay mainit talaga.

Try installing fans in a push pull configuration. One fan pulls fresh air in and the other acts as a exhaust fan. Computer fans work great, dami sa SOS. Or just relocate your amp.

I don't think its your alternator cause if its the alt, then your prob should be consistent. Also it should be giving you problems when you turn on lights, a/c etc..

James,
Try mo doon sa mga shops na na mention ko. Personally, kay TEAM cars ko palang nasubukan pero they all have pretty good feedbacks/reputations. Di ako makapag recomend ng brands kasi di ako updated.

[v6dreamer]

mga bossing, tanong ko lang kung ano ang tamang wire size para sa power cord ng amp tsaka speaker wire para sa subs.. i'm using a 600W RMS na monoamp tsaka audiobahn sub na 500W RMS. isa lang po yung sub ko. gauge 8 yung power cord ko ngayon tapos d ko alam yung sa sub wire.. baka kse undersize yung gamit ko, sayang naman pag d mamaximize yung power ng amp.. tnx in advance.

For Sub.
Thicker wire-10, 8, 4, 2 gauge ang maganda depende kung gaano kahaba ang gagamitin mo sa lakas ng power amplifier at kung anong balak mo gawin.

Sa Amps na may put out na 50 watts x 2 channels o kaya 25 watts x 4 ang 10 gauge ay pwede na. Kung balak mong ilagay sa trunk ang Amps mo at gusto mo ang malakas na togtug, 8 or 4 gauge ang gagamitin mo. Laging tandaan na ang Amps ay require a lot of current to handle loud, low bass notes, and the thicker the wire, the more current it can deliver.

"CABLE LENGTH"

Amperes ----12gauge ----10 gauge ----8 gauge ----4 gauge ----2 gauge
125-150 ----4-6ft --------7-10ft -------11-14ft ---- 15-19ft ----19-22ft.

105-125

85-105

65-85

50-65

35-50

20-35

0-25

Current estimate.
First, add up the fuse rating of all your Amps. Now figure your amps total steady state average output(divide total RMS wattage by total peak wattage). Then multifly your fuse rating total by your Amps total steady state average output. This gives you a rough estimate of how much current your sound system is going to require.

Estimate your electrical systems reserve current capacity..
Tingnan mo yung alternator amps rating and multifly it by 40 percent. Ito ang pinakamalapit na base line estimation ang electrical reserve
capacity ng iyon kotse. Halimbawa, kung ang alternator ay may rated na 90 ampere, 90amps x 40 percent = 36 amps na lang ang natitirang power sa sounds system mo. Kung ang figure mo ay mas mataas kesa ito your in good shape.

Needs more advance about details of perfections just ask.

boss userfriendly question ulet,, pwede ko ba ikabit lahat ng channel ko sa seps ko na 2way? yun amp ko yun mtx4244

[userfriendly]

boss userfriendly question ulet,, pwede ko ba ikabit lahat ng channel ko sa seps ko na 2way? yun amp ko yun mtx4244

Pwede bridge channel 1 and 2 and connect to right speaker. Bridge 3 and 4 and connect to left speaker. Just make sure both crossovers are set to high pass or all. If all make sure you have passive xovers on your seps. However, I think it this will give your seps too much power, 200 watts each. If I remember correctly your seps are rated for around 60 watts, tama ba? Baka pumutok ang speakers mo. Also, take note that this setup will be hard to tune. I think you will be in mono.

ahh thanks,, so talagang 2 channel lang mabibigay ko sa kanya opo 60rms lang yun seps ko,, thanks po sa suggestions

Userfriendly, tnx for the advice. But it does give me problems with my lights dimming. Pag ma-bass talaga that is. Have also tried to mount 2 of my old 120mm fans in the amp, it didnt work unfortunately.

If I opt for the secondary battery option, how much would the improvements be?

Your subs system is grabbing all the power almost to a point, you could be asking for trouble.

OPTION ONE..
You will need a Farad Capacitor to ensure that your system gets steady supply of power for maximum performance, and act as stabilizer between the amps and your car's electrical system. 2.0 Farrad Capacitor is ideal but, 5, 10, 20 or 40 farrad capacitor are much, much better.

OPTION TWO.
Have your alternator rebuilt for higher output or you can invest in a high-output aftermarket alternator.

Secondary battery wont help. The only reason to do is to play your stereo for long periods with the engine off.

[v6dreamer]

mga bossing may tanong ako hingil sa matching ng power rating sa pagitan ng amp at speaker. ang dami ko na napuntahan website sa pagresearch kaso pare-pareho sinasabi nila dapat yun AMP equal o mas mataas(lagpas kalahati) kaysa SPEAKER daw.

so kun ang speaker ay 100w dapat daw 150-200w ang AMP (in rms). hinde ko makuha ang dahilan kasi logically dapat speaker ang mas mataas kasi parang masisira yun speaker nun agad. kaya yun ang dahilan kun baket hinde ako makapagdecide kun ano bibilhin sa pag upgrade ng sounds ko sa tsikot. tama po ba ito?

at huli tanong meron po ba kayo alam na mabibilhan ng AMP na may built-in digital surround decoding.

salamat and more power to tsikot!!!

Have you ever try tuning your stereo and amps system?
If not this is how you do. Set your speaker amps gain to the lowest setting, then turn your stereo on, play a CD or Tape, turn your volume up to 80 to 90 percent. This setting mahina ang sounds ng speakers, turn your amps gain in clockwise slowly you will notice your speaker getting louder. Keep turning your gain until your speakers start fluttering then stop. Lower your gain just a little until speaker working normally. That is your crossover point. So regardless how strong your Amps you will prevent damaged from your speaker if you tune your system. Usually 40 to 60 watts RMS is enought for full range speaker.
Your speaker.... 100 watts doesnt means RMS on your speaker but output wattage.

Example..

Amplifier: 60 x 2 (RMS) * 14.4 Volts
Peak power at 4 omhs is 200 x 2 and 100 x 2 at 2 omhs.
So if you wired your speakers in 4 omhs load (series)and your Amps 60 RMS your amps could supply you a whooping 200 watts each channel on each speaker. Now, if your wired your speakers in 2 omhs load(parallel) your amps could supply your speaker about 100 watts each of your speaker. Bridging your Amps RMS into one load(for ex,.. subs or diff. multiple amps setting configuration) this 60 x 2 RMS amps would become giant 200 watts RMS pumping out a 400 total watts power. Can you see your amps configuration now? When the said equal or more is true but not RMS. Look at your speakers watts (100) and the output of the Amps (not RMS) output power are double (200 watts)on 4 omhs load and 100 watts on 2 omhs load( 2 omhs load is a pair of speaker that wired in parallel using one channel of your amps) meaning 4 speaker total on your 2 channel amps.

EXAMPLE:
60 RMS x 2= 200 watts x 2 at 4 omhs load
60 RMS x 2= 100 watts x 2 at 2 omhs load
60 RMS x 1 (bridged)= 200 RMS = 400 watts

Huling sagot sa tanong.
Built-in digital surround decoding.

I have a stock 2000 SiR and I'm planning to setup my car audio.

I have an initial budget of 10K

In the near future, I can add 10-15K more.

With my initial budget, please help me select setup and specs that can be upgraded later.

Ano po ang final setup na kaya ng 20-25K?

Ano po ang dapat kong unahin...... with 10K

"Sound Quality & Bass (boom boom)" is my target.

TIA to all who will help.

Good question. With so many in-dash stereo's to choose from, how do you pick the right one?
Before I answer your question let me ask you a little about your basic objective, how far you will go to get the system you want. You dont have to answer this into me but yourself.
Now,Learn about products and technology youll find what to look for and get the detailed product info, create comparison and look for product review. If you starts from scratch get a stereo w/ at least 2 or 3 preamps outputs for your expansion option on a later date. This is your first step. You dont have to buy the whole system for now but you can built it little by little.

Next is speaker. Buy a good speaker with higher sensitivity rating, the louder it will play from the amount of power it receives.
Recomended for front speaker is component system or two way maybe tri way depends your way of listening. Rear is 6x9 or 6 1/2. This is your second step toward your target.

Amplifiers. Buy a four channel amps to bypass your stereos amps for more better impact. Make sure to buy an Amps with a preamps output for your next expansion of you system. Preamp output means is you could connect your amps with another amps for your sub w/o buying separate crossover.

This is your basic set up that can upgrade almost endlesly. This for now and remember if you do your homework the first time, could save you a lots of money. Hindi yung, ay mali sana yong mas malakas ang binili ko. if that thing happen gastos na naman.

[carz_zoom]

Thanks for your reply V6dreamer

Ito po ba ang dapat kong unahin?

1. head unit
2. speakers
3. amplifier

Can you please give me brand & model of the above so that I can review the specs.

Thanks again

Ooooops! Im sorry, I cant help you with that ask locally since dont know what kind of stereo's you guys have there in phils. Dont be dissapointed ask a friends or someone you know that already has in thier car or any car stereo's gallery. The most important is, you know what you want. Good luck!

[james0207]

sir userfriendly.... ok b mga 4way speaker?
btw... ok dn b un mga sub with box sa concorde?

[v6dreamer]

4 way speakers is nice but you cant drive much power as the two way speakers. A 4 way speakers is consist of wooper, midrange, tweeter and super tweeter. That concorde, I dont know!
