Contour Enthusiasts Group Archives Forums Modifications Audio Possible to bridge Head Unit channels?

I was wondering if it was possible to bridge the front and rear outputs on a head unit to get more power. I was thinking about running front speakers only, and bridging the front and rear.

Nope not usually, unless it specifically says in the decks manual.

For about 99% of HU's, no. There were some built by Pioneer a few years back that could bridge the rear channels to a single sub. The bridged rear channels were probably good for 50w at most.

Grab yourself an inexpensive 4ch amp. You can get something decent off ebay for $50 or so. Pick up a 4ch amp install kit from www.knukonceptz.com to install it.

Most of them, no. My very first car CD player was a Pioneer than you could bridge the front and rear channels to drive just the fronts (or rears... whichever) It sounded maybe 1% better. Bridging an amp almost always causes distortion and a lot of times, the speakers only pulling like 1 or 2 watts off the deck/amp anyway.

Best solution is a small dedicated 30watt or 40watt per channel amp.
