I have a knwood headunit with a front and rear set of preouts. I just brought a mtx sub and a audiobahn amp for the sub,but I want to add a audiobahn 2channel amp for a set of Infinity 6x9 speakers for my rear. My question is what would be the best way to hook up the two amps to my system.
You can buy rca splitter from Walmart/BestBuy/CircuitCity or any stereo shop. It takes 2 rca jacks and turns it into 4. If one of your amps has "pass thru" rcas then use that. As for power, get a power distribution block. Makes it lot easier to connect multi amps to one power wire. Yes you can share power, ground and remote wire.
