100w Head Unit...attaching it to an amp for 200w speakers?

Question

Im gonna sound like a dufus, but, that's possible right? 100w amp..connecting it to an amp to power 200w front speakers, then bridging for my sub?

Answer 1

You have to pick one or the other, I think. Either drive the fronts with the amp, or bridge it and drive the sub.

If you bridge, you have to try to run all three speakers off the bridge (interesting - it would work, but I've never tried it). Be forewarned that your subwoofer recoil will attempt to back-drive your full range speakers inductively. Shouldn't be any big deal, because the frequency will be low, but.....

Never have tried this.

Answer 2

That is what I did in my car. You can do that by bridging the subwoofer and then tying one speaker to the left channel and the other speaker to the right channel. Just tie the positive from the front speaker to the positive from the subwoofer and the negative in the correct spot and the negative from the other speaker should be tied to the negative going to the sub and the positive in the correct spot. Make sure your amp is in Full-Range not Low-Range and make sure your speakers can handle the 200 watts. If your amp is 200 watts rms you are going to need some fairly high end front speakers. 100 watts rms isn't so bad.
