Odd Bridging Problem

[neo_styles 10+ year member]

Turning to you guys for help again since I can't seem to fix this issue.

I was trying to bridge my comps on my Eclipse 36501 today and am having trouble with some level control. With my channel switch on 5-ch, the left mid and tweet go super-quiet and right speakers play at their proper volume, but I have control over sub level. On 4-ch, the levels match on comps, but the sub is outputting at the same crossover point that the HU is set to. I run low power, so I'm not worried about burning out the sub, but I'd like to know what's going on.

Also, in 4-ch, I can't adjust the sub gain or crossover, but in 5-ch I can (at the expense of the attenuated left channel).

Any advice? I'm starting to pull my hair out and start looking for two separate amps at this point.

Any advice? Other than buying a new amp because at this point, funds are dried up.

Manual for the amp? How do you know the amp is not crossing the sub in 4-ch mode?

Can't seem to find one. Got this used from mclerico here. It's not crossing the sub because regardless of the crossover position on the amp, sound stays constant and I can hear the vocals through the sub itself. LPF maxes out at 200Hz and I know you can't hear most of the dialogue at that point.

Lol figured it was kinda odd. In the meanwhile, I'm trading my Rockford for an OS Jap-made Kenwood 2-channel.

I suspect the RCAs. If they are wired out of phase internally it would do what you describe. Swap the RCA left vs right and see if the problem changes sides.

Forgot to mention I have tried swapping splitters, but not the RCAs themselves. Once I have my DMM and can put some measurements on the AT RCAs I just got, I'll be sure to do a quick swap and see if that helps. I won't be keeping the Knu RCAs in there anyway.
