Is it alright to bridge the 4 channels, into 2??


Recommended Posts

I've decided i would rather give my speakers a little more juice since i listen to music mainly instead of 4-speaker games. So i was wondering if there is any serious problems with running each sat on the front and rear channel? I have the inputs running into a splitter so the signal for both is the same. But i'm wondering if the fader will cause problems with this setup? Also....just to make sure i'm doing it right. It goes front positive to front left, and negative to rear left? Then same for the right speaker??

are you trying to just split the inputs together so the front and rear speakers sound the same, or are you trying to actually connect both pairs of speakers to the same channel in the amp? i don't think the latter would work, because the speakers probably aren't designed to take 130 watts (maybe peak, but not RMS). even if it did work, the sound would be really imbalanced because the midrange and treble would be a lot louder then the bass.

I mostly mess around with CarStereo amps when I do any bridge-ing and am not sure about how to do it on the Promedia amp. But what I do know is that in order to bridge a car amp, what you do is normally connect both wires of the speker to the positives terminals of the two channels you are trying to bridge. In addition to that, there is a bridge mode setting to the amp that allows it to do this. I'm not sure if the ProMedia amps have this feature. If you try to bridge your speakers in the way I have explained, probably nothing would work. Or the thing might blow up on you. Give it a try and let me know...hehe.

I think that most speakers weren't ment to handle that kind of impedence. The sats get to something like 3.6 ohms at full blast. I also think the fader will mess it up unless you can find the setting where the front and rear are equal.
