So im running a dual amp system. infinty 7504 and m500 alpine. Both power up great and sound is clear with my new system. However. When i turn it on. faint his then a small poof. and when i turn it off. BIG boof. I tried it with either or amp connected. Both pop solo and when both powered. Powered on distrubution block. 4awg coming from battery to block. 8awg to the amps. Right now i tried grounding right under the reat seat. sanded down those two 12mm bolts and used that. still nothing.

Anybody have any advice as to where is the best place to get a great ground back here? Its driving me insane.

Power wire and rca are on opposite sides.

 

a trick people do is installing a relay on the remote wire. It delays the turn on and turn off and usually takes care of that.

 

do you have a link or a quick walk through?

so after some troubleshooting. it was determined that some wire in my harness of HU is bad. its sending this faint double pop to the door speakers only. amp is fine. so remotes are fine. im going to get a new HU later anyways. redo the wire harness and go from there.

 

Ah that sucks. If you need any more help let me know...car audio is one of the few things I know about.

 

Car audio is my biz too if you need help wiring a relay or whatever just hit me up I would be happy to help
