Re: IX704

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

Altanator noise coming out speakers

this usually means you have a power wire or a wire that has power running through it ran too close to your RCA wires or speaker wires and it's picking it up being so close. Another thing to check, make sure everything is grounded really good. All else fails, try buying a ground loop for your RCA wires. Hope this helps!

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 sound from speakers, but there is power to amp

make sure the power wire and the remote wire have voltage. at least 12 volts. make sure the ground wire is good and has a good solid ground. after that make sure the rca cables are getting signal from the radio. if you have a small speaker or tweeter you can touch the wires from the speaker to the rca cables and it should play music very quietly. meter the subs and make sure theyre ok and not shorted or bad. if all that checks out good.... the amp is probably bad. start with all the simple stuff and work youre way up. if the amp has good power and signal and good speakers then the only thing thats left is the amp. good luck

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

firstly, you might want to check if the resistance of your speakers (out-of-circuit) are in specs using an ohmmeter. If it's rated 4-ohms then it should be reading near 4-ohms resistance otherwise it is damaged.
secondly, if the amps can be powered 'on' make sure that it has no dc voltage in the outputs. If there is a signal source an AC voltage will dance the meter pointer which indicates that your amp is OK. Only then can you reconnect your speakers (not the damaged speakers duh!).

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.
