Wiring 2 MM6501UM + sub to 5 channel amp
I've been looking at the Polk 4000.4 but I need something "marine" rated for an open top '75 scout. I have 2 of the component MM6501UM speaker/tweeter sets that I want to send 125w RMS to, and am looking for a good marine sub around 400w. I want to power everything with one amp, class D preferred, and am wondering if I get an amp rated at 60w RMS @ 4 ohms per channel, can I somehow bridge the 4 speaker channels into 2 outputs to send to my components, and then run a sub at 2 ohms somehow to get the extra power from running at 2 ohms.
Thanks in advance, hope that explanation was clear :) I tried searching the forum and couldn't find anything similar.
