[QUOTE="Rochambeau, post: 2296998, member: 570071"] what amp are you using? I know when I tried to bridge a PDX 4.150 amp, I had to take the FL and FR inputs out of the source (in my case a processor) and split them with two "Y-cables" to go into the 4 inputs of the amp and the amp then "summed" the split signal for each channel. That is to say Left went to channel 1&2 inputs and Right went to channel 3&4 inputs. At that point, the amp put the L signal back together by adding the Ch 1 & ch 2 inputs and also adding the ch3 & ch4 inputs for the right. Then you simply plug the left speaker positive into the positive for channel 1 and L speaker negative into the neg for channel 2. Finally, there is an input selection switch on my amp that had to be set properly to assign the correct inputs to the correct channels. PS: When I did this little trick all was fine... except I had the wrong speaker specs and cooked a new pair of Boston Pro60's cause they couldn't handle what I was throwin at them. Oopsie!
