*When connecting the speaker output leads of the head unit to this unit with an RCA extension cable (sold separately), etc., you do not need to connect the remote turn-on lead, resorting to the “REMOTE SENSING” function of this unit. However, the “REMOTE SENSING” function may not work depending on the signal source connected. In such a case, connect the remote turn-on lead to an incoming power supply cord (accessory power) in the ACC position.

great 4 chan amp

I have this amp running my door speakers. 6.5 comp fronts and 6.5 coax rears (both alpine type r). Its clean and easy to set up. I expected a little more power, but it rocks for the price.
