I have a Pioneer MP5500 HU with two sets of RCA outputs : 1 for the Sub and a 1 for the Right/Left channels. I have a Four Channel US Acoustic Amp powering my Infinity spkrs in the front 65w/ch RMS and a single, bridged US Acooustic Amp hooked to the sub RCA from the HU. - I'd like to bridge the four channel Amp and shoot some mo' juice to the Infinities but I just have the 1 RCA's going to the amp. Can I Y adapt off the HU Single RCA and plug into ch. 1 & 2 on the four channel Amp? Will it be Stereo? Easy on the near deaf newbie !

You would just need a Y-adapter for the positive and negative RCA. If you did it at the HU you would need to run another set of RCAs, if you did it at the amps you wouldn't.

There isn't a switch on the amp that allows you to bridge it with out running another set of RCAs?

Also some amps you dont need to run another set of RCAs and can just bridge it on the ouput channels so there is no need to run more RCAs. It just depends on the amp...

Look in the manual and it should tell you how to do it.

 

At the amp do the following. get the single female to dual male y adapters. Take your left channel signal and go to channels 1&2 of the 4 ch amp then bridge them to your left speaker. Take your right ch. signal and go to channels 3&4 of the 4 ch amp, then bridge those channels to your right speaker and you will basically (not physically of course) have a higher powered 2 ch amp that will function in stereo as you are wanting. The only concern with doing this would be your final impedance can't be below 4ohms.
