Make shure you are using good quality shielded wires for carrying low level signals from your radio to your amplifier.

Make sure its a good ground. Make sure your audio cables running from your radio are not running on the same side as your power cables running to your amp. Sometime that can cause alot of noise in the lines

Loud noise from subs amp is grounded well


Check the output of the amplifier with the input connections disconnected. Does the sound go away??

If it does, then connect each input one at a time and see what happens. If the sound appears, then do the following:

The ground connection on RCA connectors don't always make a good electrical connection. This is the outside ring. If the RCA connector goes in easily, the the outside ring should be compressed slightly to garantee a snug fit. Do all of the RCA connectors, at the amplifier end and at the radio end.

It could be the way that the amplifier was installed. the ground lead should run directly to the battery NEGATIVE terminal. This will greatly reduce noise produced by other equipment.

What's the best way to hook up my jl audio 13" w 7 sub to my jl audio 1000/1 amp


the best way? hmm. i would start off with some wire. Keep in mind that you will need to separate the positive (usually red or has a stripe or marking on it) from the negative (Black usually is the common color for this wire) and hook the up according to your amps positive and negative hook ups / terminals following your sub-woofers terminals. then depending on your sub woofers Voice coils (Duel or single voice coils) yours are duel or quad coils but i\'m sure they are duel (2 of each positive and negative equaling a total of 4 posts on each sub-woofer). figure out your amps ohm load handling and does your amp run hot (1,2 or 4 ohm stable some are even less like 0.5 or lower) i would run at a 1 or 2 ohm load as that is usually standard on 1 channel amps. make sure to check your wiring and if your not sure about ohm loads just Google wiring for sub-woofer ohm loads such as 0.5 ohm, 1 ohm, 2 ohm or 4 ohm loads. also make sure your box is not sealed do to the fact they are siht and cant produce sound like a vented / ported enclosure keep the size as big as you can fit in your car or truck the bigger the better. i had one 8\'\' sony sub pounding like a 15\'\' sub real loud . Also MDF particle board is garbage it causes port noise and absorbs water

Loud noise coming before start new song from usb pre amp


The problem is that you dont have proper earthing on the amp so that is why you will get a engine idling noise. you may need to put in a device called a supresser which will connect to the amp, or try using a 8 to 10mm earth cable from amp to the booth body for earthing. also make sure that you are not taking the earth from your car battery cause that will cause the noise aswell. hope this helps you.

Try moving your ground wire(black) from your amp to a different spot.

There is a engine noise coming out from my speakers


(1) If you have an ohm meter check from neg terminal of battery to body of your car. It should be below 1 ohm. You should get the same reading between the amp neg terminal and the amp ground point. Check amp ground with the power off and the wire to the negative on the amp temporarily disconnected. Most cars have a braided uninsulated ground strap from the engine to the body or frame. In older cars this can break and it usually causes noise. Run a temp ground wire from the battery neg to the bat neg of your amp, if the noise goes away it's a ground issue for sure.
(2) Make sure the amp is well grounded ! The bolts that anchor the seats to the floor are one of the best ground points I know of.
(3) I've fixed a few amps that had an internal broken connection from the RCA's on the amp where they connect to the circuit board. This often happens from not having the amp bolted down and/or the RCA's getting hit or kicked. This will cause noise in the amp and requires taking the amp apart to fix it.

Earthing an amp


I FOUND WHEN RUNNING MY AMPS IN MY COMMODORE, THAT THE BEST EARTH IS ACTUALLY THE SUB FRAME OF THE CAR!!
AS IF YOU FOLLOW THE NEG LEAD FROM YOUR BATTERY IT WILL BOLD ONTO THE CHASSIE OF THE VIEHCLE. SO I JUST EARTHED OUT ALL MY AMPS AND SO ON TO THE BODY (MAKING SURE THERE WAS A GOOD CONNECTION)
ALSO MAKE SURE YOUR HEAD DECK IS NOT TOUCHING ANY METAL PARTS IN WHERE YOU MOUNTED IT!!!!! GOOD LUCK....

Jl audio with 2 12kickers cvr


it sounds like you don't have enough power to run the amp, or else it is a built in (MOSFET) overload device inside the amp. the woofer is from your discription blown. when you choose a amp and woofer you need the woofer to be able to handle more watts (MAX) than the amp can give or you will blow every woofer you connect up. you can solve the power outage by fitting a "CAPACITOR" which stores power and provides it to the amp as and when it is needed, or you will need to install another battery for the amp alone.

Diferent sound


The entire difference may be due to the vehicle.

He could check things like the B+ reaching the amps when driven hard. It should remain well above 12v. If it's dropping below 12v, that could be part of the problem.

He also needs to check to make sure that all woofers are in phase. If he has one woofer connected improperly, it would only be approximately as loud as one woofer because one would be cancelling another out.

I have a xm6660.... yellow light...


There are some things I want you to check, 1) Make sure your ground is good and I mean very good, 0 ohms resistance to the negative battery terminal 2) Make sure that your AMP is grounded to that ground point you checked in step 1. 3) Make sure that your power supply B+ wire is one continuous run no taps or spliced connections. 4) Your speakers and woofers are all properly impedance matched to your amplifier (if your amp is 8 ohms then your combined speakers impedance must be 8 ohms total). 5) voltage regulation to amplifier is good. 6) Check all connections and ground points again After these items are done power on your unit and then see if the problem happens again, if it does the issue is inside of the unit, one of the internal components has gone bad and you will need a schematic, a multimeter, and an audio tracer to work on the AMP with.
