Power Shortage after sound setup! pls help

**bobo_d_wiseman** · February 16th, 2006 08:56 PM

guys, masters, gurus, eto po sound setup ko:

94 Honda Civic Hatchback
stock alternator/ ac delco small battery

pioneer in-dash cd/mp3 player
targa x-series 6" fronts and 2" tweeters
macrom crossovers
overdrive 800w, 4ch amp
12" aura sub in an abc box

very basic ito right? am i supposed to encounter problems after this setup? ganito po kase nangyayari:

1. pag umaga, everything works great
2. pag gabi, naka-on lahat ng lights, namamatay ang amp at stereo at humihina ang headlights ko.
3. when i turn off the aircon, ayos na sounds, pero mahina headlights.
4. when i rev up, lumalakas ang ilaw, tapos mag-o-on ang sounds then off ulit after rev drops.

sabi sakin normally kaya daw ng stock alternator ng hatchback ang basic setup na yan. so, anong problem? battery ko is new. alternator daw baka mababa ang charge rate.

eto po questions ko:

1. kelangan ko ba mag-upgrade ng higher amp na alternator? magkano yung amp at magkano pakabit? (may conversion pa right?) ilang amps? at kasya ba sa hatchback?

2. ok na ba yung stock alternator ng hatchback? bili nalang sana ako ng same type as stock. para wala ng babaguhin. (mas mura ba to?)

3. or mag-dagdag ako ng 2nd battery? magkano to? (re wire, kabit, etc.)

important po sakin ang price kung ano mas mura, ok na ko dun. i dont think kelangan ng higher amp alternator for that basic setup. sabi sakin charge rate daw ang i-check kase mabilis ma-drain ang batt. ano po suggestions nyo?

overdrive 800w, 4ch amp

800W RMS or Peak power?

try installing a ground kiting, its the most cost effective solution for this problem see what happens.

if that fails, look to upgrading your alternator or install a capacitor, I prefer the alternator upgrade. but before that try using another amplifier with a lower power rating. Since your using a ABC box, a "weaker" amplifier would be enough - lets say around 150W - 300W RMS.

Stock pa rin ba ang headlamps mo?

At ilang amps ba ang rating ng stock na alternator ng hatchback? Baka nga kulang kung 800W RMS yan. Pero pag hininaan mo ang gain or volume ganon pa rin ba?

Wiseman,

800w amp mo, upgrade ka muna battery. Suggest ko sayo Optima, tulad ng akin. OK yun. Kung kulang pa rin, upgrade alternator ka na.

Mga cars like yours, tamang tama lang alternator rating sa stock. Baka maliit alternator mo.

i suggest having your alternator checked because of number 4

pa check mo nalang alternator mo. siguro mababa rating nyan. mas maganda mag upgrade ka ng alternator with higher current rating (around 80A to 110A) para ready narin for future upgrade.

thanks for the replies.

iluvdetailing: yup, nagkabit na ko ng ground kit. saka capacitor.

the wild thing: di ko po alam stock amp ng alternator eh. stock pa headlights ko. planning to get hids sa birthday ko. hehe. (o yea, i need more power for that right?)

flagg: il have my alternator checked muna. kung ok naman ang charge rate, il get a battery nalang na low drain. ok ba yun?

caloyski5 and mcbry: yea, definitely mukhang upgrade nga ko ng alternator. meron bang bolt on lang na universal? para wala ng convert-convert? how much usually yun?

thanks brothers!

o yea, fyi, di pa ayos ang problem. pinapa-body repair ko muna minor dents ng auto now. so suggestions at comments, are still welcome and appreciated.
