You're amp is not getting the maximium power then it once was. You must tighten the ground or reground it scrapining the metal. There is a lot resistance somewhere in your system. recheck your power connections making sure they are tight and not corroded already especially near the battery. take out the old fuse and replace it with a new one and see if the amp improves its power.

Sometimes the fuse internally breaks loose and has a bad connection without looking bad. You can measure this with a multimeter. See what the voltage on the side of the fuse holder away from the battery is. Is it 12 volts or does the voltage drop drastically.

The power button shows dim blue light instead of regular deep blue. the light panel shows yellow light insted of all bule lights


this could be a simple ram prob, try removing the ram via the back door underneath the lap top the try rebooting, or find the cmos jumper and reset the bios/ cmoss settings, if the ram is not the prob it may be the graphics card has died, hope this helps

MTX Thunder series 7402 Amp cutting out at Hard pound.


Most likely the ohm load is too low, if you have the subs wired in parallel rewire them in series and see if that resolves the problem. if not then you do not have enough battery power to support the draw that the amplifier pulls. if the vehicles voltage drops below 11.5 volts the amplifier will momentarily shut off, similar to how the lights in your house dim when the a/c cuts on due to the sudden power draw. hope this helps. p.s. if you cant afford another battery right away, lowering the crossover frequency to around 65hz will greatly reduce the amount of current necessary to keep the amp pumping. (in my opinion it sound better that way anyhow.)

My 1990 toyota corolla tail lights and dash lights stopped working after i hooked up a stereo and sub and amp system...i checked the fuse and its good..i cant find any wiring problems..help? anybody?


which fuse did you check. verify the wiring to the radio than comes from the light switch to the radio. if all this worked before , then it has to be work that you have done. the only link from the light switch to the radio is for inst panel dimming. first disconnect that wire and ck fuse for tail lights. make sure there is power on both sides of the fuse, use a test light.

My subs sound distorted and dont pound right 2 12in cvr kickers and a kingwood 2 channel amp think its not wired right


Are you sure the polarity is correct on the sub's connectors? This is very important as reversing them will cause the sub to pound inward instead of out. Make sure the wires are thick enough and that the amp's + connector goes to the red(or +) connector on the sub and that the amp is grounded properly to a clean piece of metal on the car's body. This ground wire should also be as short as possible. Also make sure the fine-tuning for the bass level on the amp is adjusted correctly and that the sub's enclosure is the correct specification ie. Ported or sealed, right size, etc.

Kenwood KAC-8401 light goes from blue to red when turned on


Either the amp is ad or the sub got shorted? You can check itby disconnecting the Sub and seeing if the amp comes on blue then. If yes, then the sub is shorted. If no, then the amp is shorted. Also chck the voltage AT THE AMP. Make sure that it is above 12 Volts.

My Jbl mono amp cuts out


It's likely that the amp has blown output transistors. To eliminate other possible problems, read through the following page:
