    Hi when you say you have distortion can you describe what this sounds like - In many instances distortion can be caused by a poor ground connection from the amp. to the vehicle chassis. Make sure the area where the cable eyelet is clamped to is perfectly clean with no rust or paint present. Once I know what form of distortion you have I can advise you further.

How are your power wires and RCA cables routed? Right next to each other? If you run RCA's next to power wires you will pick up "radio noise". Separate the cables. Power on one side of the car and all signal (RCA) cables on the other. Also make double sure you have a very good ground. That can cause noise as well. If you have the amp negative to a seatbelt bolt or a seat bolt make sure the connection is clean. Use some sand paper to remove all paint and other contaminants. Make sure it is clean bare metal. Also make sure the amp negative is as short as possible. Hit me back if this doesn't solve your prob.......

Subwoofer in truck is getting interference

Hi whit kendrick

Probably your amplifier is defective, an amplifier that produce an audio that drives your speaker. Try to open your amplifier box and if you notice that a component attached on heatsink, thats an amplifier.

When connect power, Clip signal On and do not Sound Why this is?

Oversimplified, "clipping" is distortion. Clipping can damage speakers. You can reduce or eliminate clipping by reducing the amplifier's OUTPUT volume; or be reducing in the amplifier's INPUT signal. Excessive amounts of either can result in clipping.
Check out this video for a more in depth discussion about clipping. I hope this was helpful!

I have ks-ax6801 1200w max. connected to 2 subwoofers cs-gw1200F but when you step up the volume of the headunit the amplifier clips.whats the problem....

To prevent clipping, you need to turn down the gain or bass boost on your amplifier. The reason this is happening is because the head unit is telling to put out a certain amount of power, and the amplifier, well... amplifies it based on your gain level. Reducing the gain should stop the clipping.

MY amp is going into clip mode. what is clip mode on an infinity car audio amp?

either your pushing your subs to hard and its creating a backsurge of resistance, or the spider wires are touching the frame causing them to foul out. It honestly sounds like you are trying to run too low of an impedance subwoofer, and your amp infinitys clip to keep from distorting, distortion played through a subwoofer at high volumes is damaging to the subwoofer and the amplifier. reduce your gain, and check your wires, the clipping should stop, a good rule of thumb always have an amplifer that will do rms what your speakers can do peak, so that way you can keep the amp turned up only 1/4 of the way and be pushing your subs at a decent rms volume with 0 distortion.

Can i connect the amplifier and subwoofer to the built ford fiesta radio

If your amp has rca jack inputs only you will need in-line filters to reduce the stock stereo speaker outputs down to less than 3 watts. If your amp has high power inputs you can use those. If your amp does not have a built-in crossover then you will need to install a low-pass crossover or filter before the amp so the only the bass comes thru or the sub woofer will have major distortion. Another problem is the amplifier needs a turn-on signal for the blue wire and most factory radios do not have one. That means you will have to tie that wire into the switched 12v wire from the vehicle so the amp comes on when the key is switched on. It can be done be done but I don't think you will be very impressed with the sub due to most factory stereos have a limited bass range. Most aftermarket head units have built-in crossovers and sub outputs. They also produce much better sound than the factory unit. So in other words yes you can.

Subwoofer sound interference

it sounds like you may have unshielded patch cable (rca cables) or they may be coming loose from either the head unit or at the amp which could cause the same thing and it may also have a cut in the cables but in my opinion it has to be the head unit or the patch cables cause there shouldnt be anything else in your car that would cause that phenomenon. more than likely the cables are loose at the head unit in my opinion if you have another amp available to you i would try it and see if it reoccurs if it does and most likely will you need to take out the unit and if the cables are completely in you could have 2v preouts which sometimes in conjunction with other factors seems to cause also

sorry i couldnt just tell u whats wrong
