Are those 2000W from ebay any good?They're way too cheap to be any good if you ask me,but i don't have $800 to spend on an amp.I need at least 600W rms power but more is better.Here's one of those cheap amps

there are cheaper ones.Anyway,you guys think they're any good?

Moving to CoOp.

Anyone who is seriously into car audio will tell you that clean power is far better than cheap bulk power. The brands that I will recommend to you are: JL Audio, Kicker, eclipse. Soundstream and Pheonix Gold have a few good amps but you have to be picky. If you don't care about anything but loud blaring distorted bass then get any of the other brands. I personally run a 400watt PPI (It is a year 2000 amp which unfortunately was the last year the PPI made good amps) to JL Audio 10" W0 subs and if you have the volume up a bit the subs will put your face into the windshield but still not be distorted. I like accuracy in my music so for subs I will recommend JL AUDIO, Kicker, Eclipse. The JL Audios do seem to have a bit more bite than the other two for the amount of power that you run to them. If you want sound quality and accuracy follow the brands I have recommended if you just want loud distorted bass this amp will work just fine. I hope this helps

By the way you can bridge any of the amps listed above and get double the power in mono you know.

Just go to ebay and search for kicker amps. The reason that it will be better than the cheap crappy boss amps is becuase of the THD (Total Harmonic Distortion rating) is much lower the more distortion the amp has the more interferrence your subs are recieving, cheap amps with high THD ratings will easily blow your subs after a short period of time. They have an 800W@ 4ohms mono kicker amp that is running for under $400 (with a buy it now option)

Yeah i posted this on another board and got alot of replies,i didn't go with those cheap ones,i got me 2 amps from a website though,one for the sub,and the other for the speakers.

what kind of amps and sub did you get?

I already had the subs,2 12's but i'll only use 1,as for the amps they're U.S. acoustics.
