best amp

The worst thing you can do to your subs is underpower them, what bberman1 said is correct (nice job btw) nail down you sub and then nail down the amp. If you want these big nasty subs then you also must be willing to power them properly. If you want to go in the reverse order, that's fine as well, nail down the amp and then we'll all give you recommendations on subs. What do you want to do that you belive you need 4 subs for? Are you trying to annoy the neighbourhood or do you just want some good loud sound for you tht you can listen 2, there is a drastic difference between the 2. How much real estate do you want to give up in the trunk, this is another determining factor on you choice of subs and amp. What cd are you going to use? If you have not asked these questions at a store, then the CLERK will sell you what you want instead of a sales professional selling you what you need.

well the last couple of cars that i have had i had two twelves and at first they sounded great then its like i got immune to it or it wasnt loud enough for me. i want my auror to sound real good and i dont want to have to change my sounds unless i have to. thats was my choice for going with the 4 12's. i might even conssider three but i know for a fact that it wont be 2. and the subs that i have chosen to go with is the pioneer speakers. at first i thought they were 500 watts but i found out theat they are actually 800 watts. so i got the speakers nailed down now i am just trying to get a good amp at a reasonable price that will do the job i am trying to accomplish. if by cd you mean what head unit i have the jvc kd-sh9700
