Power Acoustik is not one of the world's great amplifier brands. I'd stay far away from that.

I agree... also, subwoofer amplifiers should be either class B/D or class D... but its not a good idea to use class A/B amplifiers on subwoofers

thanks doc

well, let me slightly rephrase what I wrote earlier and try to qualify the statement...

without getting into too much techno mumbo jumbo, traditionally, Class A/B amplifiers provided better sound quality than a comparable class d amplifier. Since sound quality is needed for higher frequency ranges (i.e. 100Hz --> 20,000Hz) amps for interior speakers were and are almost always class A/B

due to the fact that subwoofers only typ[ically reproduce frequencies between 25Hz and 150Hz, the switching speed of the amplifier doesn't need to be as high as that of an amplifier that has to switch between frequencies over a greater range (i.e. 100Hz --> 20,000 Hz)

so , in essence, class D amps , for a given price, are much more efficient at doing a job that only spans 125 or so Hz of frequencies. A class A/B amp that has the efficiency of a class D amp at lower frequencies, with the same RMS power handling would cost thousands of dollars!

So long story short, due to the design of class A/B amps, and the fact they were designed to try to effectively reproduce large bandwiodths, they are just not as efficient at amplifiying just a small range of frequencies... and if they are, they would be expensive as all hell (i,e, tru technologies amplfiers that can run you about $12,000 retail for a custom amp)

so, if you find a cheap class A/B amplifier, from a cheap company, chances are.. not only will they only be average at producing the entire bandwidth, but they would be very inefficient used in the case of a subwoofer application....

I hope this makes sense, I tried to use as little industry jargon as possible

I'd first ask what Kickers are you looking at. They vary with 2, 4 ohm and are you getting a single or double speaker box?Decide on which box, sub enclosure then work on getting an amp with that rating.

i have 2 12inch Kicker CVR right i trying to put a box together seen ebay doesnt do 12" they just only do 10'

This isn't me but searching for stuff found the perfect fit for your subs:http://longisland.craigslist.o....html

yea that box is ok but its a little to big for my taste. im trying not to take up all the space in my truck of my car

[Blood1]

Yeah but didn't you say you have 2 12" Kicker CVR's? what other way are you going to mount/install these two w/o taking up so much space. You might only need 1 really. I don't know for sure. I'm going through that right now deciding on which sub/amp set to get. Still looking... and yeah I want a small footprint solution. Something I can easily take out of car if i have to go pick up something and fold down seats.
