How do i wire up a diamond audio d6300.4 to run 150rms x 2 @ 4 ohms? how many rcas do i need, 2 or a 4 channel? Do i need the amp to run in 2 channel mode, or have it run in 4 channel and bridge? Do i run it with channel 3/4 mono on or off?

You need to have one set of RCAs coming from your front outputs, and then have splitters right before the amp and put it into all 4 channels. Then for the left speaker use the far left and far right outputs on channels 1 and 2, and the same thing for the right channel except channesl 3 and 4. I would imagine your run it with all channels on but if there is a switch for bridged, choose that.

if you have componets you should run em active , cause i do belive d6 amps have bandpass crossovers.
just a thought.
