You should have a ground cable that connects from battery directly to car chassis.This cable should be right next to battery and is usually short about 6- 12 inches .The other ground is very thick and goes to engine .Sometimes you have to scrap paint from metal inorder to get a good ground

Hello M8

lots of things can do this and the installation is the most common issue.

some simple rules:

never install the powercable and RCA cables together on the same side of the car.

keep the rca cables as far as possible from other wires if possible.

ground cable not grounded propably (Clean metal surface on chassi)

bad RCA cables eg: broken/Loose (Use shielded cables)

use the same diameter on both possitive and negative powercable

it could be a problem with either amp or sterio too if everything above is ok

I installed a jvc kdr310 with a pioneer amp and single 12 in sub all worked well and as soon as i drove off less then a quarter of a mile down the road my head unit stopped functioning and said protect i...


the fact that the head unit cut out and went into protect implies that it probably has nothing to do with your pioneer amplifier. If i understood well the amplifier is running the sub woofer. If the speakers are running off the head unit check that there is no speaker cable touching metal causing a short. Sometimes while installing the speaker we don't realize that the speaker terminal can touch on the frame of the surface that it is secured to. If this surface is metal then you get a short, which then makes the head unit go into protect. There is also the possibility that a cable from behind the head unit has come lose or is bare in some place touching metal again. You see it is all usually about being shorted. Without knowing exactly how everything is installed, this is the best i can do. I hope this helps. dreamsystems

My car stereo makes a thumping noise through the subs when i turn it on or off,also when i change songs on a cd and if i turn the volume all the way down too.i have tryed changing the wires,subs,amp, what...


You have to be more specific. Subs thump, that is their purpose. You need to be more in depth about the sound, because it sounds like the subs are doing their job by thumping out bass

Install amp in chevy hhr


First do you have an aftermarket stereo? If not you'll probably want to purchase one. You don't NEED to have an aftermarket unit, but i highly recommend it. Assuming you use an after market unit do this. First determine where you'll mount the amp, choose somewhere secure, and not in a tiny compartment. Once you've decided where you'll put it run a minimum 6gauge power wire from your battery to the amp location. Within 18in from the battery on that power wire, insert a 95-100 amp inline fuse. Next run a maximum 20in ground wire from the amp to a chassis ground(if none is there you'll have to make your own, just drill a hole in the aluminum and bolt the wire down)with also min 6gauge. Make sure all the paint around the hole is scraped off and has only bare metal. Next to connect your stereo to the amp, use RCAs. The back of your aftermarket unit will have RCA outputs, run RCA cables from these and plug them into the amp RCA inputs. Note: there's multiple outputs on the back of the headunit, use the one marked sub, or rear, assuming this amp is for subs. Next on the back of the head unit is a wire that is blue with a white stripe, connect this wire to the slot on the amp marked R.E.M. now just hook up your subs an listen to them plow!!!!!!!!!!!! side note when running your RCAs place them on the opposite side of the car from the power wire, this will avoid alternator whine in your subs.... good luck if you have questions please ask.

I cant hook up my amp


Hello cesar199064,

These are the steps you required to install your amp and subs:

1) Purchase an amp wiring kit with 2 or 1/0 gauge power and ground wires.
2) Decide on a location to mount the amp where it will get proper airflow and will not interfere with operation of the vehicle. Closer to the battery is better. Decide on the location and install the sub enclosures.
3) Locate a place on the metal body of the vehicle within about 3" of your amp for the ground. Connect the ground wire to the amp ground terminal and to BARE METAL on the vehicle.
4) Run power wire from battery positive (+) using one of the amp kit ring terminals through a 100A fuseholder to the amp positive terminal. DO NOT install the fuse yet.
5) Run a "remote" wire from the remote turn-on lead (usually blue or blue/white) of your dash mounted head unit to the amp turn-on terminal. Run a set of RCA cables from the preamp or subwoofer outputs on the head unit to the amp inputs.
6) Run speaker wire, preferably at least 12-gauge, from the amp output terminals to your subs.
7) Check all of your wiring. Make sure that no insulation was damaged or peeled off during the running process. Make sure there are no loose strands touching adjacent terminals or bare metal.
8) Use a multimeter set to read "ohms" and test from the negative battery post to the amp ground terminal. You should read "0".
9) Install the fuse.
10) Turn on your head unit and listen to those big Kickers thump.
11) Adjust the amp settings according to your manual.

The best place I've found for in depth information on audio installs is The Install Doctor. You'll find step-by-step procedures, color photos, wiring details, and even the tools required. I recommend that you begin with the "tech docs" link and read through some of the PDF documents.

Hope this helps.

Sounds as if you may have a bad ground. try running an external ground from the radio to a bare piece of metal underneath the dash.

Wiring installation on Majestic amplifier total 60watts 2x30 model# ma-60


To install the amp you need a amp wiring kit they range from $15 and up depends on how many watts u have.Once you have the wiring kit start with the ground wire it needs to be no longer then 24 inches long the shorter the better find a good ground in the trunk or where ever you want to install the amp make sure its metal to metal no plastic paint or any other debrie is in the way of the metal.If you can't find a paint free surface all you will need to do to fix this is sand off some of the paint and then ground the amp.The ground wire needs to be connected to the amp before any other wire once you have the ground connected then connect the battary wire make sure you have the right size inline fuse on the battary wire that also depends on the watts of the amp.once you have those 2 wires connected then u will need to pull the stereo out of the dash and hook up the remote wire to the power antanna wire if you have a factory car stereo and don't have a power antanna you can try one of these solutions 1st one Run the remote wire from the battary wire on the amp and use a toggle switch between the remote and battary wire or you can run the remote wire from the amp to the fuse box of the car and hook it up to a fuse that only works when the key is turned on.Once you have all this hooked up its time to hook up the subs/speakers on the amp it should indicate if its bridgable it will show lines from one positive and one negative and at the top of the lines it will say bridge but if not the just connect the speakers positive to positve and negative to negative.If it is a bridgeable amp i would only recommend hooking it up bridged if you are hook up subs if you are using 6x9's on the amp you don't need to bridge the amp.If u have any more ?'s just ask i can help with this i've done this alot.

Cant figure out my car audio problems!!!!!


There are a couple of tests you can perform. I'd first recommend checking the shield ground. You'll need an ohm meter. The details can be found on the following page.

RCA shield ground test

You can also test the output with the multimeter. Set the multimeter to AC volts. If it's not an auto-ranging meter, set it to a voltage range of ~2v AC. Disconnect the RCA cables from the head unit. Touch one meter probe to the outer ring of the head unit's RCA jack. Touch the other probe to the metal contact in the center of the RCA jack. With the head unit near full volume and a clean signal source, you should read at least one volt on musical peaks. If you have a bass disc or a test tone disc (~60hz sine wave), use those.
