    Amp ground wire location

    Howdy. I had an amp installed a while ago, and am just tired of the engine whine. I'm also getting distortion or interference from either the brake lights or the wiring. The guy who installed said he tried multiple locations for the ground, and settled on the one in the attached picture. It...

    Grounding issue

    I have a nice bare metal body ground in trunk reading 0.2 Ohms compared to the battery terminal. When I turn on the ignition, the resistance in the trunk jumps to 40 Ohms when compared to the battery. I also checked from battery to the front seat bolt (not seat belt), and same thing. Key off...

    Sub amp issues

    Hey everyone, So I just recently switched my sub and amp to a car I just bought. It's a 05 Acura TL, which has a stereo that's difficult to remove and retain all channels/speakers. I tapped the stock subwoofer remote wire, ran that and my power to the back, tapped the stock sub's signal and ran...

    Hooked Ground to + and + to Ground...but

    So the amp is a JX10001d. Such a dumb thing to do(No bad smell came from the unit. Took about a minute to realize and unplug it) But the odd thing is with it wired correctly now the power light comes on the amp and everything seems fine. No fuses got blown anywhere and when the vehicle is turned...

    Hello! So the rule goes you should not ground to a painted surface... once you have cleaned the surface free of any paint, and made a connection. Can you then paint over your ground to prevent rust?

    4-Channel Amp Wired to 1 Sub Continually Overheats

    Hello friends. My amp and sub setup in my trunk works well except that the amp overheats regularly. It's a 4-channel amp, so I have two options for wiring the sub: bridged and unbridged. When it's unbridged, it's weak but it doesn't overheat as much. When it's bridged it sounds awesome but...

    Too many power/ground runs?

    Ok, so I crunched some numbers today after cutting holes. I have enough wire and lugs to do sixteen runs of power and another 16 of ground with my Sky High 2/0 OFC. Now, I'm not completely stupid. That's wayyyyy overkill for just about anything. My question for yall' is how many runs you...

    Grounding Issue?

    Hey everyone. Recently I changed my ground to clean up wires and built a new box. With the new setup my electrical seems to be in HORRIBLE shape. My lights used to dim, and the bass would hit hard. This setup was run at 1 ohm, pulling about 1500 rms. Now, my lights and even amp lights (Hifonics)...

    Checking For Best Ground

    Hey everyone, I was wondering how do I test a ground spot to make sure it's the best choice? I'm getting ready to do the big 3 and I want to make sure my grounds have the least resistance possible. I assumed I take the negative of my multimeter and clip it on the negative battery post, then take...

    Do you like my ground?

    The place where the spare tire is tightened. I sanded it and went to the hardware store and got the right size bolt and a washer. What do you think?

    Grounds for dismissal

    To put these questions in context; while I'm familiar with basic electronics, I'm very new to car audio and the nomenclature involved in it. I'm building an adapter harness to mate a new HU to a factory amplifier, and I'm confused by something. I understand that there are different sorts of...

    Problems with my 3.5 Farad Capacitor

    Ok, I have 2 Alpine Type-E 12" connected to a Boss PH2.800 1600w amp (2 x 260rms at 4ohms) and a 3.5 farad capacitor. Now, I have a little issue with the capacitor, when I turn up the volume for more than 20 the voltmeter goes off and the capacitor start making a beep sound. I have a 4 gauge...
