I have a kenwood kac-9152d amplifer and it works just fine for about 10 minutes then just shuts off and subs dont work, about 30 seconds later my amp turns back on with the subs.


make sure it's well ventilated. If there's no air flow, then there is no way of cooling down and to protect itself it will shut off. Make sure the speakers are wired correctly as per amp specs. too many subs or subs connected improperly can draw too much current and shut the amp off, but you will notice this when you turn up the volume to a certain point and the amp shuts down.

I have't IR remove control. It's broken. What's can i do to control this amplifer?


You can run a wire from the fuse box to the remote wire at the amp. Find a ignition switched power lead out of the fuse box inside the car that way the ingnition switch will turn the amp on and off .

12 volts to amp, when connected no volts, it turns on in my friends car.


The ampliflier require an amount to power volts to perfrom. You friends car may have a power stabilier installed to produce appropiaet supply to stereo systesm. usually, a direct wire from the engine to the amplifer may least function as manufacturers default specifcation. If the amplifer performs at all, a fuse is blown to protect the devices in wiring cuircuits. if the device functioned in another car, it is not damaged. Consult with an auto electrician to attain appropiate wirign or acqurire the component parts to wire the vehicle. Important notes. Each device usually will have an instruction on installing. However, the power source from engine depending on type of vehicle may require regulators to share the current to stereos amplifiers and speakers.

When i try to hook up amp no lights turn on.im pretty sure it works.how can u tell if its burnt up


first thing to do is smell it, second thing to do is to take the bottom covor off to visually check for damage, third is to bench test it with a car batter, a regualar 4 ohm speaker that you know works, and a cd player with rcas going into the amplifer, this is the best way, then if it works on the bench, it must be something with your wiring, bad ground, loose battery clamp, etc.

I have everything hooked up correctly and cleanly, but when i turn my truck on the blue light flashes on then off and my subs do nothing. I don't know if its shorting out or what is going on.


sounds like a loose ground, or a loose positive cable or possibly a blow inline fuse, and the only power your unit is getting is from the remote. triple check all your connections. use your senses, smell the amp, smell for a burned order, this usually identifies if it is something internal. but it sounds like in your case (from experience with) a bad ground. If your gound or positive is connected but not tight it may be enough to power the remote circut, but not good enough to handle the actual turn on (Click) of the circut. powering the led light usually takes about .5 amps, but powering the turn on switch usually takes anywhere from .5 to 20 amps, then the inital charging of the capacitors that are internal on every amplifier... that quick charge pulls a decent amount of curren fast (usually the first 2-3 seconds) to fully charge a small amplifer after it has clicked on. hopes this helps

My lightning adio amplifier will not turn on. i touched two wires together an now it will not power up for nothing


What it sounds like is that your blew the fuse on the amp. Not that big of deal and not too expensive. Make sure when you buy another fuse that you get the same size. If you don't know what a fuse is google either, car fuse or amplifer fuse

REVERSE TERMINAL WIRE AND TO MUCH VOLTAGE 18 TO 12V AMPLIFER


The Power Mosfets may be damaged and therefore causing your power supply fuses to blow. The fuses on your amp may be higher current rating than the ones in your vehicle and that is why they are not blowing

Mrv1507 power light blinks red..


Your speakers probably are made for 6 or 8 ohms. to check, take out any of the speakers and read the back for the ohm rating, if it is more ohms, you need a more powerful amp.

Light stays red


I do belive this amplifer has a red light when it is on... I know my Kenwood does. I suggest checking all your wireing between your amp and your speakers, check the impediance between your positive and negative terminals on your leads to the subs.
