Hey folks,
I've presently got a 2-channel amplifier powering some upgraded speakers in my Subaru Forester. However, I'm thinking about installing a subwoofer, and it'd be nice to just swap out my current amplifier for something sufficient for the speakers + subwoofer, instead of adding a second amp. My question is whether or not I can have a 4-channel amplifier accomplish this task of powering 2 speakers (not bridged) and a subwoofer (bridged). I would assume so, but I want to make sure, first. Here are some candidates I've found:

Also, would it be problematic to have my amplifier under my passenger seat, and the subwoofer all the way in the trunk?

Just a general reply.


yes, four channel amps are great for powering a pair of front speakers(components, coaxials, whatever) and bridging the rear two channels for a sub. I have had this setup a few different times in different vehicles. it's great for less wires, and less space taken up.
