4 channel cuts out

[brafferty]

receently my b2 has been cutting out. I normally listen to the head unit turned to 27, but now when it hits 12, it goes silent until i turn it lower, than comes back on. All fuses seem normal. Any ideas?

Bad power or bad ground. Possible remote issue. Exhaust it's available power and it shuts off.

ill check those all out and see whats up! ill probably be moving this install to a new car in the coming week

so i took the weekend to run all new wire to the amps, and still nothing, same issue as before. but now i can turn it up to 16 before it goes into protective mode. The sub amp works fine and they are both grounded to the same area, so i dont think this is why. All fuses are in contact.

What are you grounded to?

What are you grounded to?

excuse my poor car terminology,but im grounded to the back hatch area, right by where it locks closed. The b2 has a 0 guage wire for the ground and the JBL has the 4 guage ground sitting on top of it and that amp has no issues.

Do you have a picture? Is it to a factory bolt? Is it sanded down to bare metal?

I would then suggest turning it up until it it turns off, unplug a speaker and try again. Repeat for each speaker. See if it doesn't cut off with one of them disconnected. I would also try the same with the RCAs.

i actually did this as well (the speakers that is) because i tossed my rears back in just for a change. With 2 speakers in it makes it all the way up to the 27 again. And by RCAs what do you mean? wouldnt unplugging them just turn that channel off as well?

Look more into the speakers... disconnect left see if it goes to 27, reconnect and disconnect right and see what happens. If it works both ways, try bridging the other 2 speakers and see if it cuts out.

did that, when bridged it cuts out, left side cuts out, right side does not. Maybe an issue with my crossover somehwere?

Sounds like an issue with your left channel. Have a second amp to try?
