What is the electrical system in the different car like?You may need to get a secondary battery for that amp.Also ceck your in line fuse,it may need to be larger.Sounds to me like you either do not have enough power,or a ground is not connected.

It has stopped workin and the red light is flashing.Is this a code and if so how do you read it


The red light is a power protection circuit designed to shut the amplifier down due to an overload or wiring problem. If the amp was playing then shut off, my guess is a problem with the speakers or the speaker wiring. Some amplifiers are only stable to a certain load. For example, most car audio speakers are 4 ohms which is the resistance placed upon your amplifier to produce a certain volume of sound. If you bridge two 4 ohm speakers together in parallel, you cut the resistance in half, thus increasing the amount of power (and volume) to your speakers. This also creates more heat and could, in effect, shut your amplifier down. I would find out how the speakers are wired to determine the resistance of the load your amplifier is pushing. Also check the grounding.

sorry to say that you proably fried the amp. there is a way to check, find the air vent on the amp, and smell it, if you smell a burnt smell, its fried. you might get lucky and the amp might be under warrenty

My red light on my amp is on and wont go out


Unfortunately I think you need to get it repaired or replaced .When a protection light will not turn off it is generally caused by an internal short and needs one or more replacement parts for it to come alive again.

This error indictaes that the upper thread is broken. If it is not the sensor is telling the computer the thread is broken. Try tightening the upper thread tension some and rethread the upper thread.
