Quick Amp Bridging Question

[bimmeracer 10+ year member]

What is the proper way to bridge my 4 channel jbl gto75.4 to my rsd's? I removed my rear fills and only have the two wires coming from the cross-over.

Is it just Front L (+) + Rear L (-) for the left speakers and Front R (+) + Rear R (-) for the right speakers?

Thanks

you still got the manual for it, it will tell you in there, if not go to there site and look for a place to download it, they usually have em

I have the manual but it only tells you how to run front speakers and bridge the other two channels for 1 sub, not how to bridge 2 cross overs bridged to the 4 channels.

just bridge it down to two channels run one to each xover. or run the channels right and use the amps xover...

Thats what I want to do, but I dont know how to bridge it down to two channels.

You're making this more difficult than it is.

Replace the "sub" in the diagram with the passive crossover, and duplicate on the other side.

Im not trying to, but I cannot get a clear answer. If I send one cross over to the front and then one to the rear, how will the cd player know which is the left channel or the right?

Do I need a Y-adapter to send signal to rear?

Why do you have one crossover for the front and one for the rear //content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif

Maybe I'm not understanding exactly what it is you're trying to do.

Are you trying to run two subs from that amp? If so you may not be able to use the bass boost for the front channels.

I guess the question is what type of speakers are you running, how many and do you have a crossover other then the amps built in xover?

I am trying to figure out how to set my 4 channel component amp to 2 channels to control my front components. on each side of the car I have a tweeter and a driver running to a cross-over, which means I have 1 + and 1 - wire coming from both sides. I would like to know how to wire those wires up so that the amp is bridged to two channels and it can also recognize which speaker is L and R.

Is the correct way:

Front L (+) + Rear L (-) and Front R (+) + Rear R (-)

or

Front L (+) + Front R (-) and Front R (+) + Left R (-)

or something else.

Thanks
