Re: Geo Prizem no power to start as key is turned

It is possible that you burned out a fusible link (a short piece of wiring, specifically designed to fail, to keep your car's wiring harness from melting, when your car's starter is overloaded), which is located somewhere between your battery and ignition switch. More than likely it is near the fuse panel of your car, but isn't mentioned in your owner's manual, because manufacturers don't consider it a part that owners are qualified to replace. If you don't have access to a shop manual, you are best advised to take the car to a qualified repair facility. It sounds like possibly either the ignition timing is off or the cam timing, causing starting problems, although it could be that you've gotten a poorly remanufactured starter motor. It is next to impossible to diagnose a car (especially the most complex part of the car: the electrical system) verbally. Suggestions and guesses are the best that can be done.

My amp kx1200.1 works only 5 minutes and then getting real hot somebody have any idea

You need to swap your main battery for a high performance kinetic... and maybe even ad a small kinetic in the back as well (fused separately) and see how that works for you. Just one oversized kinetic battery replacing your stock battery may do that trick. Remember, its best to install two batteries of the same brand and size, its ok to use the same brand and two different sizes (a kinetic 2400 and a kinetic 600 for example, but with an isolator) but its easier and simpler to just put in a kinetic 1200 or something that will replace your stock power sucking ineffecient lead acid stuff.

Fried 3 amps. Is it my car? 93 mustang gt. I had my original amp Rockford Fosgate punch 500@2 for about 8 years then the whole system got stolen. Bought the same one on Ebay and it was fine for a few...

make sure you run your ground and power wires on one side of the car and the rca's on the other, keep them sepparate. if you have all wires running to your amp(rca's/12v power/remote), then you run the chance of either getting interference from the alternator, or if you have a pinched wire(usually by the door step) it may short with your battery wire. Double check your rca's and make sure they're ok and also check for corrosion on your wires.

Have Power going to the amp. Amp does not turn on. Do i need a remote? Bought vehicle with amp in it. LXA 600 Power light does not turn on.

you need to make sure you have 5 things.

1. power connection to the battery/amp
2. make sure you have a remote line radio/amp
3. make sure you have rca's radio/amp
4. make sure you have a ground amp/car frame ( scratch paint away for good contact)
5. make sure the speakers are connected to the radio.

if all is ok then check the inline fuse from the hot wire from the battery is not blown and the fuse on the amp is not blown.if so replace them. with the proper amp fuse.

No sound from subs

take a 9 volt battery and touch the speaker terminals quickly.
they should move and make a noise if they are not blown voice coils.
do not leave the voltage on it for more than 1/2 second,as the dc can burn out the speakers coils

Kenwood KAC 7202 amp not powering on

First you should test to be sure the amps main power feed is supplying 12+ volts to the amp. and that the other connections (head unit remote lead - input & output signal leads) are properly secured, if all is well then there maybe an internal issue with the amp.

It is not recommended to affix an amp directly to a speaker/kicker box, hence the vibration that may cause wire connections and/or internal electronic components to become loose or faulty.

As far as "should i take the amp apart and look at its guts"

NO, sorry but given the way you phrased your question I can assume that your electronic troubleshooting knowledge is not up to par, and that task would be a waste of your time.

Good luck

Capacitor digital display shut on then off

It sounds like you have either a dead battery or a bad connection in the power supply line from the battery. A blown fuse can cause the voltage to drop. This is fairly common with glass fuses in fully enclosed fuse holders. You need to use a multimeter to see where the voltage drops between the battery and the amp.

add doide from the battery to the unit, 2 doide should help that.
1 connected to the positive, an 1 connected to the negative. 5-10 amperes is ok. check for the polarity. and try to take off the ground of the unit then try it.

when your amp cuts out,is it when your stereo is produceing a long low note.if it is then the problem lies within the power distribution from the your sub pulles a long low note it draws a lot of power and sometimes the battery cant supply the power fast enough and the amp cuts out. useing a power cap is one way to solve the problem,but the best option for you to use becouse your running high powered amps is to have a sepparate battery for your audio using a split charging system.when your car battery is fully charged a relay swiches the power so that it charges the audio battery,so your auio system will have constant power without putting stress on your car battery. you can get thes from all good audio shops. hope this helps you.
