Wiring 4 Channel Amp

Post by nelobynature »

I finally have all my gear in and the car disassembled but I'm still not to sure on how I'm going to wire my components.

The amp is an PG rsd300.4 which is going to power front rsd65cs components.

My original plan was to bridge the amp at 4ohm to power just the two components giving them about 96w a piece. But then I read that by bridging a 4channel amp you lose stereo sound because they can only be bridged front and rear not left and right, which I'm not too sure if it's the case with this amp.

Therefore my only other option would be to just save the rear channels for rear coaxials whenever I get em, even tho I was planning on running them off deck power.
This option though would only give 48w at 4ohm to the front comps, which doesn't seem like much considering iv'e heard they can handle a lot more power.

What would my best option be? and is it true that I'll loose stereo sound by bridging the 4 channel?

Bridging the amp is no problem.

Get some y-splitters. Run your right bridged off the front (connect Y-splitter to the RED rca, and then connect that to your front inputs). Same thing on the rear.

oh ok cool

and do you think there would be a major noticebale difference between having the front comps bridged at 4ohm versus just running them off individual channels at 48w/4ohm or 80w/2ohm? I'm trying to figure out the best possible configuration..

Like i said when I get around to putting in rear coaxils, i could always just run them off of the deck, so bridging-if the optimal choice, would not be a problem.

With them on the front only, you'll get 50x2. With them bridged, you'll get 175x2. More power = more volume and control. You lose a bit of sound quality by going bridged, but I doubt you will notice.
