    How to wire my 4-ch as 3-ch

    Sorry if this seems like a stupid question but I just don't to mess anything up. I have a CDE-HD149BT headunit and a MRP-F240 4-ch amp. I am currently running my fronts on 2 channels and I want to use the other two channels for a sub. The headunit has 2 sub-preouts.
    Thanks

    You just bridge channel 3 and 4 to your sub.

    Thanks. That was pretty easy. Sorry to steer this in a totally different direction but.... I've found a JL Audio 250/1 to run my sub and I am thinking about bridging the Alpine to the two fronts. The speakers are Polk MM651. Would bridging degrade the sound quality at all? I am looking for the best sound quality possible, not necessarily the loudest system.

    not really. Technically your going to increase the distortion from the amp, but you will NOT hear it. Amp distortion is always very low unless the amp is clipping. Bridging the amp will give you more power and make you much less likely to clip as well as increase dynamic range. Go for it.
