tommyboy Posted August 8, 2015 Report Posted August 8, 2015 Check where you connect your rcas to the amp, try and wiggle them and see if you lose/gain output. I'm having a similar issue with my soundstream rubi 2500. It used to work fine but now I get about half my output. I tried moving the rcas where the male connections on the amp were and found out that they were loose, thus causing the problem. So try that and report back.

Boyakacsha Posted August 8, 2015 Report Posted August 8, 2015 Check the gain knob, DD has had problems with bad gain knobs recently and the problems have manifested themselfs in all kinds of manners.
amanley Posted August 9, 2015 Author Report Posted August 9, 2015 Interesting thanks guys I'll try it all and let you folks know.
