[QUOTE="charha01, post: 8702660, member: 678910"] [SIZE=4][FONT=arial]I've installed a [/FONT][/SIZE][FONT=arial][SIZE=4][B]Pioneer AVH-2500NEX head unit in my car and paired it with a Kenwood X802-5 eXcelon amp. I cannot get rid of what sounds engine noise coming from the alternator and was hoping for some advice. I've changed the grounding point for the amp to several different spots, even grounding directly to the battery ground and that has made no difference. I've also run a 4g ground wire from the battery to the head unit ground to see if that would help but it also made no difference. The RCAs coming off the head unit go through the firewall and are routed behind the battery since that was the only path that would work for the installation. Could this be causing the issue? Is there anything I can do to find the cause of this noise? If it is the RCA cables, is there anything that can be done to shield them from the battery? They are shielded cables, but I'm wondering if their proximity to the battery is causing the issue. Also, I'm using the factory power wiring to power the head unit. Should I run a dedicated wire from the battery for this instead? Should I ground the [/B][/SIZE]chassis[SIZE=4][B] of the head unit in addition to using the ground wire coming off it? I've read that you can install filters for alternator noise, but all the ones I've seen online look too cheap or get bad reviews, so is there something that someone would recommend? Any help would be appreciated. Thanks[/B][/SIZE][/FONT] [/QUOTE]
