I am about to complete my system and all I need now is a decent 400 watt amp, I put my friends amo in my car for a while and it just didnt sound right. this is my set up, Alpine CDA 7894 HU, 4 pioneer 6.5 3 way speakers, 2 JL 10w0s and the amp I used was a 300 watt 2 way pyramid amp(AKA pile of ****) For some reason, im guessing the amp, the sound quality was crap and the bass just didnt sound right. Even with tweaking the sub control on the HU it sounded ****ty. That would be because ogf the bad amp right? What would you guys suggest for a amp to fit this system, the subs are rated at 250 watts a peice I think. I dont need an amp for the speakers either because it is a 60X4 HU and I dont need any more power to the seakers. I am not just after bass either, I listen to all types of music, Sound quality is my #1 so that comes first, but I do want to be able to pound if I want to. Suggestions? Thanks in advance.
