I spent $200 on a USAcoustic 150x2@4ohms or 450X1 @4ohms mono. This amp sounded really good running my 3 10's and I was very happy with the sound. I got another amp for my fronts and rears and had to turn up the gain on the sub amp to match and after doing this the amp lasted about 1 month and started blowing caps off the circuit board. After fixing it twice I got sick of it and spent $300 on an ////Alpine V-12 amp that was rated 85WX2@4ohms. I could not believe the difference. Not only is the alpine amp louder but the bass was so clean and clear! I will never go cheap on audio gear again.
