hey everyone, i have an 18" fi btl and i was wondering what amp you would suggest? i was thinking about the Hifonics BXI 2010D, im running it at one ohm. also my buddy has a 10 farad power acoustik capacitor..are they any good? this is all goin into a 1992 Chev caviler..will a yellow top battery be enough of a upgrade or should i get a high output alternator? lastly, what does it mean to have a box tuned to a certain amount of Hz? is it like port size? I've had big systems before just none of them have been ported. any help would be appreciated a ton!

why drive home drunk when you can fly home high! pce boys

I'm guessing your on a budget since your looking at a hifonics amp?

You don't need 2kw to properly power a btl, just a thing to keep in mind.

I would always buy quality used products before new mediocre stuff.

Your stock electrical isn't going to support a true 1500watt rms amplifier, adding a few batteries will help, but isn't a solid fix, sure you could play at full tilt for a few minutes draining your batteries all the time, then turn it down while your alt tries to keep up and recharge everything? I'd get an aftermarket alt, don't have to get anything super gonzo if your budget doesn't allow for it.

Capacitors are worthless in car audio, don't hold big enough charge to mean a damn, just another thing that discharges and requires charging (all the time).

Not sure how big of a system you could have if you don't know what a ported enclosure is...

The reason for putting a subwoofer in a box is to separate the soundwaves so they don't cancel each other out. So a sealed enclosure "traps" the backwave into the box, and the output you hear is just the "front wave".

Ported enclosure, allows for the backwave to be added to the "front wave" without cancellation. So you can theoretically get double the output if done correctly.

The lower the tuning on a ported enclosure, the louder the bottom end will be.

Tune higher and the higher tones will be louder, but you'll lose the bottom end.

I'm no acoustic engineer so my terms and wording could be off a little, but you get the general idea.

thanks bro..lot of help!
