I'm replacing my head unit in my car because the current one is broken. I only have two speakers but all the head units are 4 channels (20W X 4). I have looked into specs and owners manuals with no luck. Does anyone know of a HU brand that allows amp bridging (ie 40W X 2).
Thanks,
Joe

Thanks Brent,

I agree 100%! I was just wondering if anyone had a HU they knew was bridgable since I am in the market for a new unit.

I have never seen a HU with bridging capabilities. If you are wanting more power, you would be better off getting an external amp. An external amp is going to give you a lot better sound and clarity.

Thanks Anthony,
I have come to that conclusion, too. I read on a post, probably on a car forum, that someone bridged their amp and I assumed they meant the amp in the HU. I can' find the post but I bet they were talking about a separate amp as you suggested. I'll see how satisfied I am with just the HU.
Thanks again!

Joe

YEP, I had(still have somewhere) an old Sony XR7180 cassette stereo that was something like 4 by 8 or 2 by 15.

Just had to flipa switch!

One possibility you might want to consider: biamping. I have some MB Quart coax's that have a biamp setting on their crossovers. Use one pair of channels on the tweets and one set on the midbasses. (Some current head units have RCA sub-outs that could be used for a sub and amp while using your head unit power on your main speakers.)
