You need an ignition noise filter available at radio shack. This electrical filter blocks "engine noise" to reaching your audio amp.

    your fix is to do what I suggested..."you need an ignition noise filter" was that not helpful?

How do I set up my Coby 5.1 home theatre system. I have no clue when to even start.... PLEASE HELP!?!?

Step 1 Select locations for each of the Coby 5.1 speakers. Place the correct channel speakers in the best location possible. For example, a right-rear speaker should not be placed to the front left of the TV.
Step 2 Measure and cut lengths of speaker wire that run from each speaker to the Coby receiver. Include a few extra feet for mistakes. The speaker wire has two color wires, a red (power) and black (ground).
Step 3 Attach the red wire to the positive (+) terminal for each speaker. Attach the black wire to the ground (-) of each speaker.
Step 4 Make sure the receiver is unplugged. Examine the back of the receiver. There are speaker terminals for each of the speakers. Plug each speaker wire into its respective terminal. For example, plug the right-rear speaker into the right-rear terminal. Each terminal is clearly labeled.
Plug RCA cables into the appropriate input ports on the receiver. For example, there are RCA ports for the TV and DVD player. Plug the other ends of the RCA cables into their appropriate devices. For example, the DVD input on the receiver plugs into the audio output port on the DVD player. RCA audio cables are red and white, make sure to match the colors correctly: red with red, white with white.
Items you will need
  • Speaker wire
  • Wire stripper

I have no sound coming out of my speakers for the reciever that is hooked up to my tv. i have 2 of the spekers hooked up and the audio cable plugged in to the tv but im getting no sound from the tv t

hi,try going into your tv setting and see if thers a setting for ext speaker as sometime ther is ,this is the place i would look and the only place i would think the fault would be ,you say audio cable i take it you mean
rca cables [two cables] if not check them but i dont think its both of them faulty,def in setting somewere.good luck

When I turn the volume control on my home powered subwoofer, it makes a humming sound, then it stop working

check your connections, RCA, Speaker wires, maybe there is grounded. try other wires which you think in good condition..

Bought a hitron 3200b secondhand. installed the amp and no sound I have a 06 gmc I am using an aftermarket radio it is a lo line model made by I think dual 50 bucks at walmart all connections are good...

Bypass the amp with a small speaker or tweeter to make sure your rca input is working. Is the amp light on. Got good power, ground, and remote? Have you tried a different set of speakers on your amp?


no just not hooked up right. some cars have chassis ground speakers which can be a pain. best to let a pro do it and watch.

No sound coming from subs

You definitely NEED a source signal for the amplifier to amplify!

You should have a Main Power Wire, a Ground Wire, A Remote Turn on Wire, and RCA cables (or hi level speaker wires if your amplifier has them)
and the speaker wires to the subwoofers.

Humming sound to speakers from amplifier


It sounds like you may have a ground loop issue. I'd start by checking all the power and ground connections. Then disconnect the RCA wires from the amplifier. If the hum goes away then you should try grounding the stereo to a better grounding point, the factory grounds are usually not very good at all. Then try it again, if it is still there try replacing the RCA"s.

If the hum is still there after you've redone the connections and replaced the RCA's, you may need to install a ground loop isolator.
Both and sell good ones.

Hope this helps

RCA Pre-Out Making Producing a Mumming and a Popping Sound.

the speakers hook to speaker wires not to any thing else no power no negative poles do you have a remote shut off switch connected to amp this would be important to cut off amp

when cut off amp if you still here the humming this can be an indicator of low power being produced by alternator alternators produce 14 anything below 12 would mean replacement of alternator

if alternator fine then you need to find new ground for amp and make sure you have a good ground for sterio this can be checked with a test light
to check a ground all you do is hook gator clip to power then touch test light end to ground on radio end light comes on got a good ground (make sure not to touch any other sterio wires just the ground wire while connected to power to check grounds)
if pulsing in test light on the ground means you have a bad ground
just disconnect move to better ground

check the amp ground the same way as decribed above

Weird sounds coming through speakers

The problem is not likely the amp. The length of the ground to the amp is not as critical as a good solid connection. Clean any paint and dirt from around the ground connection. It should be clean and shiny metal. Anyway as a test disconnect the RCA's from the amp while the amp is on and see if the sound goes away. If it does then the problem is not in the amp but either the RCA cables, the RCA grounds in the head unit (radio) or bad routing of the RCA cables. Depending on the how old the car is this noise can be coming from your spark plug wires as well. As a last resort you can try a new set of supressor ignition wires for the car.

IX704 kicker

There's a pretty good chance that your speaker load is too much or else your power coming in is not sufficiant. Be sure to check BOTH the battery and ground connections to be sure they are supplying enough power. If your speaker load is too much then correct that at once before you fry your amp. Good luck.
