here is my pick from last year. just 2 12s RF Hx2 pushed by a 1000watt peak power 2ch amp. with a 3 farad cap. I did one sound off legal I believe. You know where all the doors and everything is completely closed on your car the meter is stuck to the windshield about 4in above the dash. i hit a 148.4 People told me that was pretty good with a music cd. not really sure. but I will post current pics of new system as soon as it is complete.
