? about grounding rca's

[jflash 10+ year member]

I dropped my amp (kicker zx750.1) off to get repaired. I get power and the amp does not go into protect mode but i get no sound output. The repair tech had no problems with it and after 1 1/2 hours of continuous play, it never cut out on him. He took me in the back to show me that it was working. The only difference was he had the negative part on the rca's going to the input soldered to a ground. When he unhooked the rca ground the output would cut out.

Now here is the part im not sure about because i don't know if he was trying to drum up more business or not. He told me i couldn't ground the rca's with a stock hu as it would damage the hu. I have a 2007 mazdaspeed3 with the stock stereo. Also, the amp was in the car for about a year working perfectly with no ground to the rca's.

do it like he had when it was working. sounds like he might want to sell you a HU.

honetlyive never heard of this issue lol. normally grounding rca's is to try and reduce engine. like the pioneer pico fuse issue.

dude , there is a nice panasonic head unit in the classifieds here for 50 shipped. pick it up. you cant go wrong for 50 buck. got 3 sets of rcas on it too.

I really hate the way an aftermarket unit looks in my car. That's the only reason i haven't swapped it out yet.

I think I need to do this for my setup my amp has a small pop when I shut the system off other then that it works fine tho but I do have a pioneer head unit but grounding the rcas at the amp doesn't sound too time consuming.

Well i quickly ran a ground from where my amp is grounded in my car to the rca's. Still did not turn on. Maybe ill try to call kicker?

Save your money and time and break down and buy an aftermarket HU,the one you have may have a built in amplifier in which creates issues with aftermarket add ons,amps ect.I had that issue with a 2006 TA with stock stereo and amplifier built in \problem??? Answer/ Replaced w after market unit!!!!

There is no built in amp. I specifically skipped getting the blows system for that reason. The thing that gets me is why would it work fine for so long then all of a sudden stop?
