here is the situation, i'm looking to run 2 amps (Infinity 7540a 4 channel,111W RMS x 4 at 4 ohms...and MTX MXA8001 mono, RMS Power at 2 Ohms 800 W x 1) into Pioneer deh-p8400mp head unit.
First, i will be running Rear and Front outputs into the Infinity amp, and run 4 speakrs from that (2 components in front door[150rms @4oh], and 2 6x9's in the back[100rms @4ohm])..as marked in red on diagram.
Second, subwoofer outputs will be connected to mtx amp, and eventually into 2 12" Polko Momo mm12 subs (500 rms/each).. 800+rms produced by the mtx should be just enough.
Now my questions are, how/where do i connect 2 remote leads into the head unit? i have one already that connects the mtx amp, where do i connect the Infinity remote lead into the head unit? I have provided the diagram of my head unit, as you can see, there are a couple of pins which are not being used.
Also, i want to run 2 more sets of components in my rear door, but i don't want to buy another amp, these are infiity 6010cs (270watts, 90rms). I don't care if i can't get the most out of them, as long as they produce some sound. Is it possible to bridge any of the speaker outputs in the power supply of the head unit, so i can connect these and get more than 20watts to each speaker?
Lastly, i have 1 farad Rockford fosgate cap, which i'll probably connect to the mtx....should i buy another for the mtx (i.e. 2 farad) and use this one for the infinity amp....is it necessary?
