We really like the JL XD series amplifiers. They are small in size, and as they are Class D amplifiers they don’t generate too much heat. They also have adjustable crossovers and thus we have the ability to tune the sound more accurately for the vehicle.
They are available in 1,2,3,4,5,6 and 8 channel varieties in 200W to 1000W total power configurations. The “odd” channel count amplifiers support a remote bass level control thus allowing the owner to easily turn up and down the bass volume depending what mood they are in.
