Oh yeah, as for the 2,000php active subwoofers. Hmmm.. meron naman but they're of extremely low quality. I think you can still find some tubular NBN subwoofers at those prices cguro. Lightning Lab's around 4k I think.

Personally, I won't go for them. Instead, I'll try to improve my existing setup via better speakers or better tuning.

Is it legit? Well, that depends where are you installing and buying from.

Most V12 amplifiers are knock-offs. These were popular way back in the early 2000s was because Alpine's MRV amplifiers were selling like hotcakes. Sadly, I will raise red flags here. As much as original Alpine amps are great and still solid, there's WAY MORE fakes out in the market than originals.

From my point, tunutubuan ka. A V12's going roughly >3k, you can easily buy of genuine JBL subs at >3k.

currently have front door separates power by headunit. contemplating on diy install of amplifier and subwoofer.

can anyone give step by step install procedure?

did some reading on the net but not sure... bale hindi na gagamitin yon stock speaker wire to front door and kailangan put new wire from amp to crossover?

how hard is it to snake speaker wire thru the rubber grommet of front door?

everytime mag on ng radio naka on rin amp?

**mateomarco** · August 2nd, 2013 10:07 AM

Mas advisable talaga new wires from amp to speakers para mamaximize mo yung output ng amp for the speakers

Placing wires sa rubber grommet?! Depende sa sasakyan. Usually pag first time gagalawin, may kahirapan plus kung maraming dumaan na oem wires sa rubber grommet, it will take time na maisuksok yung wires.

Everytime mag on yung radio nakaon din yung amp? Yes and dapat...May remote wire output from the headunit to the remote input ng amp which is responsible for this...kasama na yang remote wire for every wiring kit you will buy...

Happy DIY. Pero kung alangang gawin, mas okay parin painstall nalang...ako, when i was starting with car audio, nanood-nood muna and observe...after when may knowledge na and lakas ng loob, ako na naginstall...

mga sir, ask ko lang kung advisable ba na gumamit ng "active subwoofer" in replacement sa mga raw na subwoofer na need pa ng amp? thanks po

**mateomarco** · August 30th, 2013 04:56 PM

^^^Sir, what would be your reason for considering active subwoofer? For SQ or SPL use po? For what vehicle?

Whether it's active or passive has not much impact on the performance of a subwoofer. The difference between the two is that passive ones are highly customizable wherein active configuration subwoofers are like all-in-ones. It's like computers, the passive types are the ones you buy parts in Gilmore while you construct them spec-by-spec while the other is much like buying that shiny new Alienware you saw at the store outright.

Most car subwoofers are of the passive variety. This is because it's up to the installers to choose the best type of box and driver that would suit the owner's demand and taste. For example, sometimes space is an issue so an installer has to find a way to fit a >1.0 cf box inside the car.

Most home subwoofers, on the otherhand, are active. The simple ones simply consists of signal plugs (subwoofer RCAs for sub-level signals), a filter, and a AC power supply. The more expensive ones have a lot of features such as subwoofer parametric EQ, level control, phase adjustment, etc. In more cases than not, home subwoofers are quite expensive because of their extreme box engineering (like I said, the box determines the performance) which can be in the form of additional bracing, thicker panels, a more rigid type of wood, etc. which is why some people pay more than Php 200,000 for a JL Fanthom subwoofer while the less affluent settles for Php 100,000 Velodynes.

In a car environment, first know your needs.. then you construct a box according to that need. Afterwards, you worry about which driver to throw in the box. That's how experienced people do it NOT the opposite way which most people do (select subwoofer -> construct box -> done).

P.S. Most car active subwoofers simply... suck.
