If the overcurrent of DC offset lights are not green, the amplifier probably has blown output transistors.

To eliminate other problems, disconnect all speaker wires from the speaker terminals of the amp and disconnect signal cables from the amp. If it powers up normally (all lights green), the wiring needs to be checked. If it still shuts down, the amp likely has blown output transistors.

    Signal cable = RCA cables

  • Perry Babin Jan 05, 2008

    If any LED goes red with nothing connected excpt the B+/ground/remote, the amp is blown.

  • Perry Babin Jan 05, 2008

    B+ = positive 12v connection to the battery

  • Perry Babin Jan 05, 2008

    It can be repaired. Call some of the local car audio shops to see who they use for amp repairs. If you find one shop that's used by several shops, it's probably reliable.

  • Perry Babin Jan 05, 2008

    Repair charges vary greatly so it's difficult to know what the repair will cost. Get an estimate or set a limit on the repair total when you drop the amp off for repair. If it costs more than half the price of a replacement, you should probably replace it instead of repairing it.

There should be a diagram under the hood, or on the firewall or even on the radiator bracket. Manufacturers put it anywhere under the hood.

I need help?

id check remote signal with a test light and also if there is a High pass or Low pass filter either on the head unit's settings or the Amp's controls

if your amp or head unit has a High pass filter setting enabled that would explain no bass being sent to your speakers,

if you are using a separate crossover to send the bass signal check those settings too..

if all else fails
test another amp on your system (if it works that would discard problems with the rest of the system's output)

I need a schematic for the x-treme scooter

Check the batteries, they need at least 12+volts to run scooter. Blinker may be burned out or the wire came loose. If batteries are charged Two things That could be wrong are: Twist throttle is NO Good, Or the controller is BAD. You need a voltage tester, (Disconnect the Wiring Harnesses) and check voltages coming out of the controller(the silver BOX with lots of wires) and see if it is sending voltage to the twist throttle. Controller wires to the Twist throttle should read 4-5 volts.

(Make Sure You Unplugged That Wiring Harness) There is 4-6 wires in that Wiring Harness then find + and - test them for voltage from that Controller box wiring harness. If You get a positive reading out of that Controller wiring harness then the Twist Throttle thing is bad. If you get NO READING out of that Controller Wiring Harness Then if is BAD. Normally it will be the dead batteries or the Twist Throttle that go bad. Batteries are expensive, Twist Throttle Cheap. Good LUCK

Plz Help - unknow problem

Sounds like a short circut protection on the amp kicking in. It sences the power going to the drivers and cuts itself out before damage is inflicted on the subs.
