Power Acoustik PS1-4000D Car Amp

Most certified name brand amps that have 1,200 watts peak or so sell for $600-$1,000 US.

This amp may not really have 4,000 watts peak and 2,000 RMS at 1 ohm, or it may (I think its half, not certified and tested like most name brands). It goes VERY low in frequency (5HZ), is very fancy by the price and has a ton of power.

With 2 15" Lanzar VIBE subwoofers I (with the right box of course) got up to 139.5 DB (c) peak and 135 Db steady bass (sine wave 60Hz) in a SUV. Amp is only $209 and is very heavy. Love it, it is so sexy and powerful. 160 AMPS peak draw (according to the instructions), so you do the math. Made my speakers overheat (2000W peak a piece) but the amp didd'nt struggle. Very durable so far and great SQ.

Use 4 GA power and GND wire, and 10 or 12 GA wire for the speakers if you want to get full power (assuming your electrical system has 80 amperes of constant RMS power output if you operate this thing at full throttle)
