My subwoofer "pops" when amp powers on. Also have a high pitch whine coming from subwoofer, happens regardless of if the car is running or just key in on position. Does not come from the other speakers as far as I can tell.
I rewired the head unit harness and I cleaned the amp ground location. Also tried a seat bolt instead of bare metal below the seat. Tried a new set of RCA's. The whine comes thru the sub even with the RCA's unplugged, I think this eliminates the RCA's and head unit as the cause..
(I have a Pioneer MVH-S522BS, CAB-22 and SA 15v1. 1/0 GA power and ground. Stock electrical but HO alt and batteries on the way)
I'm really running out of options here. Is this "pop" and the whine thru the sub bad for the amp/sub or is it safe (albeit annoying) to run it this way?
Any ideas what I should try next?
**UPDATE** Turned out the amp was the problem all along. Swapped in an old amp and everything went away.
