The BRT also has a variable hi-level DC offset turn-on circuit for easy installation into any OEM system.

This versatility makes the amplifier perfect for a wide variety of installations and vehicles Dual Selectable Crossovers Improve Flexibility Installation flexibility is improved by the addition of dual, selectable high pass crossovers.

I couldn't believe the sound! *by E***R on September 26, 2024* I purchased this amp because I was adding a subwoofer to my boat. I have a Fusion UD-750 with 2 Fusion speakers and have now added a 10" Fusion subwoofer. I decided on this amp for the job, and I'm so glad I did! It fits in tight spaces and literally packs HUGE sound! I highly recommend this to anyone who is challenged with space and doesn't want to sacrifice sound or power. ## Frequently Bought Together - Rockford Fosgate Punch PBR400X4D Compact Chassis 400-Watt Full-Range 4-Channel Amplifier - BOSS Audio Systems KIT2 8 Gauge Complete Car Amplifier Installation Wiring Kit with Power Cables, Ground Cables, Turn-On Wire, Speaker Wire, Terminals - Amp Mount is Compatible with Harley Davidson 2006 to 2013 Batwing Bikes with aftermarket & Stock radios Compatible with Rockford Fosgate PBR400X4D, PBR300x2 or PBR300x4 amplifiers.
