I know that I should have a distribution block for the positive lead and have a dedicated ground wire for each amp, but i want to know what I should do about the RCA inputs.
There are 2 ways i can think of wiring them:
#1 wire the head unit directly to one of the amps and use the preamp out on the other Amp(I am concerned that one of the amps will "lag" behind the other.)
#2 buy a RCA splitter (I am concerned that the signal will be disrupted since it's going to two amps.)
Both of these amps are identical Alpine m500 amps each going to a 10" alpine type R dual 4ohm voice coil woofer in a ported box. I want to use 2 m500's instead of one m1000 because the subs I have are dual 4ohm meaning that in order to get the subs to drive at 2ohms each i need to use 2 amps.
go with #2 you shouldnt loss any signal doing so iv done something like that befor and didnt notic a diff in signel loss
