**Hollywood** Posted October 5, 2011 Report Posted October 5, 2011 Why does subs pop when key turns on ? Ground if fine gain about 1/4-1/3 the way up
new guy Posted October 5, 2011 Report Posted October 5, 2011 It happens to me when the amp is on before the h/u is on. Check your remote wire *current* 1991 honda crx si 2 skar audio 12s pioneer 6.5s dual 400 watt amp audio technix db 1/0 wiring kit. dual head unit
**Hollywood** Posted October 5, 2011 Author Report Posted October 5, 2011 My remote wire comes from the sum8 , I just changed out the amp and the other one didn't make subs pop
spldreams Posted October 5, 2011 Report Posted October 5, 2011 you said all the grounds are fine? did you check the ground behind the head unit? popping issues are caused by a bad ground like 90 percent of the time
02z71 Posted October 7, 2011 Report Posted October 7, 2011 i had the same problem and after a few frustrating hours, i narrowed the problem down to my cd player. pioneer head units are known for this problem because of some sort of internal fuse that messes up quite a bit and when it does it affects the signal going to the rca outputs. i was ready to send the head unit back to the company since it was still under warranty but i decided to ground the rca outputs to a small screw on the back of the cd player. its not pretty but it solved my problem
