If i were to have a 4 channel amp, would i be able to run the front 2 channels @ 4ohms to power the speakers, then bridge the rear 2 channels @ 2ohm to power a subwoofer?

 

Depending on the amp but most likely you would have to run the two rear bridged channels at 4 ohms for the sub

 

So how would i go about running front stage off the front 2 channels, then the subwoofer (dual 4ohm) on the rears? trying to get max power for the sub.

 

Use only one coil on the sub and bridge the remaining two channels of the amp. Pay attention here as the power handling of the sub is now 1/2 of what it used to be.

 

what kind of 4 ch do you have?

 

WHAT?!??!?!?!
Every dual coil sub i've ever seen has had "MAKE SURE TO ALWAYS CONNECT BOTH VOICE COILS"

 

^^^^ did you see the next part written right underneath that statement, it says "it is fine to play on the highway, vehicles will go around you".

 

ok well the answer is yes if....

your amp is stable in bridged operation at 2 ohms.
or if you have a dual 2 ohm sub then bring it up to 4 ohms.

I currently just did a 4 channel amp set up last week.
I hooked up 2 channels off the amp to run the interiors at 2 ohms stereo (4 speakers) and then the other two channels were bridged and fed a sub which was a dual 3 ohm sub. Since the amp is not stable under 4 ohms i wired the sub at 6 ohms. It works just fine, i bit underpowered yet fine.

My current system also has a 4 channel amp and i'm running 2 channels for the doors at 2 ohms stereo and the other two channels are running my 4- 8 inch subs in 2 ohms stereo.

Good luck man hope this helped you.

NO NO NO 1ch for your tweeters and the other is for the mids (this is why thay make a 4 ch amp !)

 

huh?
I guess you can do that yet what a waste of power.
