Try using some sand paper where you have the ground, grounded, it that doesnt work i would say one of the transistors inside broke off. to know if that happened shake it a little to see if you have any rattle if so you or someone you know who can solder and get it put back on

If the amp doesn't play anything but comes on you probably don't have an input signal try to get a different input signal

My 04 Camry xle will load the cd's but will not play. Is it junk?


Check the CD's. When these are copies, burned in a computer, your player could have problems playing them. Not all players can play self burned CD's. An original CD has a metallic reflective layer, with a high contrast on reflectivity. The self burned CD's only have a dye, where a laser changes the colour on the same places as the pits are on a real CD. But the dye gives less contrast. When on the player is no logo, compatible with CD-R, you can't expect it will play these. When it won't play real CD's, perhaps you could try a cleaning CD and try playing a CD again.
For that you can buy a cleaning CD, with a soft brush. dust and a coating from smoke can be removed. If the laser is defect, not aligned or not calibrated, don't try to cure that.
The brush on the CD looks like this:

I cant hear any voices on dvds played throught the dvd system just the bass and background music its all plugged in correctly and set on clear help!


Hi,
please double check your wiring again as if you cross the polaritys (+ and -) you put the audio signal out of phase, thus casing cancellaion of things such as voices.

Amp burned out but fuses still good?


this is caused by inproper wiring from the speakers/subs to the amplifier.. an amp will still put out power to subs and speakers when it's wired improperly but it won't last for very long doing it... 6 months is longer than usual....

I have a volfenhag zx-8400 amp. i dont have a manual. whats the proper way of conecting amp? its mounted on my speaker box, which is ported, 12' volfenhag 2500 watts. on the side of amp it had voltage...


The voltage prolly says like 100Mv-2v, it doesn't really matter, just know that that the lower you turn it the harder it bangs. The X-over depends on where your box is tuned, crank the knob down too about 40htz and you'll prolly be good, just don't turn it lower than your box's tuned frequency. And your rca's go to line input. And there shouldn't be a problem with mounting your amp vertically, you prolly just had a bad connection. Hope this helps if you have more questions please ask...

I think ma kicker kx1200.1 amp is blown or ma kicker L7 are gone


that would be the amp. sorry to say. when a wire crosses over, it sends a shock through the amp, there are a few things to try just to see if you fried the amp. the first thing to try is to move your ground to a different location. second thing to look at would be the fuses. alot of times the fuses will blow at the slightest shock. the amp will still turn on if you have an amp with 2 fuses, it just wont be getting all the power it needs, which could be causing your problem. also, it is worth the hour and a half to mount everything down in your vehicle. you might check the kicker website, because i have herd rumors that kicker offers a lifetime warranty on almost all of their products. best of luck, and i hope you didnt fry your amp.

Protection light


either you are playing too loud or you have a malfunctioning protection light. does your amp seem to get excessively hot, as long as it doesnt, then your problem is prolly just the light itself...
