    I have a similar problem. the car will start at first and after driving when I stop and engine is switched off, it has a problem starting again as it wont go to idle. the kicks and engine start but then just cuts off. When i eventually start it will cut off as soon as i reduce speed and clutch And This is at every give way/stop sign and I have to keep cranking until it decides on its own it has had enough

I have a 125.2 punch to a kicker 12 and it plays perfect when key is turned one notch but when car is started it cuts out. Why is this?


It sounds like you have the main power wire going to the accessory switch on your ignition or something. The main positive wire going to the amp needs to be run directly to the Battery Post Positive, with a fuse very close to the connection from the battery to keep your car from catching fire if the wire shorts out. If you have this already set up like this and you are having this problem then it sounds like you have a good battery but your alternator is so weak that it cannot keep up with charging the battery, powering the car and supply enough voltage and current to the amplifier when the car is running. Also check your ground wire to the amp, it needs to be as short as possible and have a good clean metal on metal connection.
Does the light on the amp stay lighted when the car is running or is it off?

Where and how do I feed a power cable from my car battery to my boot for my amp. I have a vauxhall vectra gls 1996. I've done it on other cars but can't find a way on the vectra. Can someone help?


You may have to drill a hole in your fire wall, and install a little rubber gromit so it doesn't leak, I would analize your engine bay, and firewall to find the best rout, make sure you do not damage any hoses or wiring. Pop floor panels and run underneath all the way back to your amp, if you run an ought gauge like I do, it may not fit under floor panels. So I wire loomed and secured with zip ties as tucked as possible. Good luck *c*

Front right speaker got wet, started cutting out. at the same time the rear right speaker started cutting. switched the rear speakers to opposite channels and this caused the right to work and left to cut....


the speaker getting wet will short it out. Shorting the output on any amp will ruin it. there is a right and left chanel with 2 outputs. Right chanel is damaged.

My pioneer 600w amplifier cuts at high volume...


Are you sure it's not a problem with your head unit? When you mean cut off do you mean the whole amp loses power or power lights stay on but sound just cuts out? If you don't know have a friend turn up your radio if you don't have a remote and whatch the light, power light on the amp. If it goes out then it sounds like a bad ground or the main power wire is'nt large enough to supply proper power to amp. I would check those that I have described first because thats what it sounds like, bad ground or power wire not sending proper voltage. When you turn up the volume your amp needs more power well when you get to a point when you turn it up and amp cuts out or off then it's starving for power or bad ground. Let me know what you find. Also if this helps please rate my help so I can get out of this apprentice status. I have 15 years exp. and 2 degrees in electronics and my business is buying nonworking amps and repairing them then resale them. Thanks

1994 ford taurus wagon fuel pump relay


Some models of cars have the fuel pump working even with the accessory turned on.

A work around is to wire a series switch on the power side of the fuel pump. Install the new fuel pump switch on the inside of the car at a convenient place. You can even hide it, and you have a theft protection switch, because when it is turned off, there will be no fuel for the engine.

When using the accessory, you can then turn the switch off. Remember to turn it on before starting the engine.

I have a 1998 Altima. It has a problem similar to your description. I cannot use the accessory to play the radio, because the electric fuel pump runs, and the heater motor stays on at the lowest position. There is no off position for the heater switch. I did not feel like going to the trouble to install a fuel pump cut-off switch. I don't use the radio with the engine switched off, therefore there is no problem for me with this.

Amplifier cuts out when turning the gain up


Make sure the amp is getting good power and ground - there should be 12V across the two terminals. Also make sure you're giving it the proper ohm oad - how do you have your subs wired up? Do your headlights or interior lights dim when this happens?
