I have all infinity system (speakers, subs, and amps), and suddenly a few days ago it stops playing. My HU Alpine still working while there's no sound. Then a minute later it starts again. After that it happens randonly. Sometimes it turnes off for an hour or so. I checked the amps, they were off when there was no sound. Then I checked the wires, both remote and power wires should be ok. My be there's a lose wire somewhere and I should rewire everything? What could be a cause of this? Any ideas? HU always working fine, speakers are fine, but the amps are turning off when there's no sound (both amps are powering up from the same power cable, and connected through the same remote cable). Thanks in advance.
