Well, I was listening to music at very low volume this afternoon and the subwoofer just cut out and started thumping, just thumping like 3 times a second.
Every time it thumps the Protect light flashes, and the goes back to normal.
It had been installed for ~ a Month and hadn't had a single problem.
DD 2512 @ 1 ohm
I Have tried the following:
The sub plays just fine when I use a rca cable with a headphone jack directly to my phone.
I tried running a different set of RCA's directly to the amp for the HU, same thing happens
I swapped the HU with a spare Clarion DB365UB, same thing, also tried the other rca's with this headunit.
