Review on BOSS Audio Systems R1100M Riot Series Car Subwoofer Amplifier - 1100W High Output, Monoblock, Class A/B, 2/4 Ohm Stability, Low/High Level Inputs, Low Pass Crossover, Mosfet Power Supply, Stereo Compatible by Lisa Starcher

I have two dual style 500w subwoofers in this amp and they pack a punch. But if you put it in the trunk like I did, the air won't be your friend, the amp has a high temperature mode to automatically shut off when it gets hot. Trust me it will turn off. The bass hits love with this feature. My car was equipped with a previous factory amp that met its death. This amp is big enough to put under the passenger seat since it will be stepped on, so the trunk.
