Hey guys, new to the forum. I really need to know what the weak link is in the JK ground. I have a 2015 JKU and the ground system on the vehicle seems to be very poorly engineered. I have a stock jeep and I installed my sound system and a back up camera. When my vehicle is in reverse, and the camera comes on I get tons of interference when / if the sound system is on and bass is hitting at even a normal level. My lights also dim. Before I go any further, I want to say that the system is installed correctly, as I have been a professional installer for 20+ years. With the Jeep JK 160 Amp alternator and it being a brand new vehicle, there is no reason the system should drain the electrical system like it does. I do not want to use a capacitor as t is not needed and is a band-aid (IMO). The two JL AMPS are wired with 4 G wire, and my grounds are about 6 " long. The amps are under the seats and I grounded them to the ground posts on the tranny tunnel (which may be the issue but it shouldn't be if engineered properly). I am not a bass head, It is a small 10" on the tailgate. The back up camera is getting 12V from the reverse light, and grounded to a bolt with paint removed etc on the rear near the roll bar. To the best of my knowledge (and maybe I am missing something) , the grounding on these vehicles is horrible. Can anyone point me to the weakest link? I have heard the Alternator ground is cheesy, and the engine block ground etc. I have not had the time to look under the hood yet. Thanks in advance.
