The signature series amplifier's sleek low-profile design makes for an effortless install that will save you time and headache. The user friendly adjustment panel makes tuning your amplifier easier than ever. We've specifically equipped our amplifiers with clipping indicators to notify the the user when the amplifier is pushing too much power. Having these clipping indicators will preserve the life of your stereo system. Our amplifiers come in a 4-Channel, 5-Channel, and Monoblock. Our Signature Series amplifiers are the only amplifiers you need to have an industry leading stereo system.
