Each channel pair has its own high-pass, flat or low-pass crossover (50 Hz to 500 Hz) with up to 12 dB of bass and treble boost, so you can tune the system without extra processors. RCA and speaker-level inputs connect to almost any head unit, a jack accepts a remote level control, and the protection circuit with thermal shutdown helps keep the amplifier safe.\u003c\/p\u003e\n\u003cp\u003eThe plate measures 10.96 x 7.24 in., and the amplifier sits just 1.43 in. deep behind it.
