is this possible or even recommended.

I want to run a single set of components in my Fb with a amp and a sub

 

You could possibly bi-amp the component set, I am not sure if you could bridge the deck, both methods are probably not too good.
Just purchase a 4/3/2 channel amp, bridge 2 channels to run the sub and use the other 2 for the component set.

 

No.

 

you can sometimes bridge a 4 channel amp to 2 channels, but remember that when you do this you are running just one set of stereo inputs to the amp so that you get one set of stereo outputs. with a 4 channel deck you are getting 2 sets of stereo outputs, a front and a rear and if you bridge you will be wanting just one set of stereo outputs. the front and rear signals will not be exactly the same like they would with a bridged amp and 1 set of inputs will and i am sure you will end up with an interesting bunch of distortion and/or interference.

 

I just gave the short answer above. How do you even plan on doing what you're mentioning? Short answer #2: You can't.

 

you can attempt to bridge anything you damn well want to. whether it will work or melt something is a different story. if you had read the sentences after that you would see where i stated it wouldn't work, ***. i generally disregard one word answers to questions, so if it were my question, the fact that you simply stated "No" wouldn't mean a god damn thing to me.

 

No you cannot, "attempt to bridge anything you damn well want to". This is an even more ignorant statement than what you posted above. Can't wait to hear what comes out of your coconut hole next. Since you're so smart, why don't you tell us how to bridge the channels in a source unit then?

 

ok first off, from his original question i was figuring he was thinking about either "attempting" (remember how i said attempt) to connect the two positives together as a single positive and negatives together as as single negative, or to run one positive, one negative from the other and then connect the other two pos/neg together, which would either melt something, blow something, or somehow miraculously produce plain shitty sound. i have seen this question asked before since it seems some people think that "logically" things like this work, hell i'm sure people have even tried it without success. i didn't say you could successfully bridge the channels in a source unit. i was simply trying to explain away the common misconceptions that people new to this type of thing might have.

 

The only decks where you can bridge is select pioneer head units but you can only bridge the two rear channels into one mono load for a subwoofer.Thats about it.Back in the early 90's blaupunt was the only company that made all there head units bridgable.I would just go with a good amp if I wanted more power and a cleaner sound.

 

Well, bridging sounds good in theory. But remember, the deck's amp is tiny and not built to disipate the extra heat of bridging. So it would work but likely damage the amp (shorten its life).

What I did, with about 5 different decks, was just wire 2 channels to each front speaker. So, the rear and front channels were pushing one speaker. The result was a severely shortned amp life and the channels kept blowing.

So you can't do ^ that for sure, and bridging is not recommended.
