New to audio need some help

Plz dont underpower. U set ur opower by ur gain. Firing down breaks up soundwaves which will increase loudness in the.cab but not outside.

didn't know any of that. ok so now its fireing down for sure. and i wont be overpowering it cuase like i said i kinda want it to last. Anyone ever heard anything about this amp? and would it work for this sub? http://cgi.ebay.com/DUB-DUB2502-500...6703504?pt=Car_Amplifiers&hash=item1c1bdf4d90

 

Don't buy that amp. I've heard nothing good about Dub. Plus you dont need both channels.
This is perfect for your sub: Amazon.com: Cadence Acoustics Xa125.2 500 Watt Peak 2-Channel Class AB Amplifier (Orange): Car Electronics

 

cadence is good stuff!

 

Update on the sub. Its froze up, but my buddy thinks he can get it to work so he is gonna work on it.

 

I have a down fireing box in my truck cause thats all they make for my year but it actually sounds better than i thought it hits lows pretty good

 

my cadence components are freakin awesome

 

I always liked Kenwood

 

ok so sine this is still here im gonna add on. Is it possible to unseize a sub? and if so how? what is wrong is that the cone moves really hard back and forth when it should move easy.
