    If there is white heatsink compound in the amp, apply some to the face of the transistor, then wipe off as much as possible. That often brings out the etched markings well enough to read them.

Dropped me a red flashlight.The problem is ?


Disconnect all speaker connections and rca cables. Leave power, ground and remote wires intact. Try turning on again. If you still have a protection light your amp is faulty. Hopefully you have warranty.

My Lanzar Optidrive plus has a green light and a red light. I assume this is a sign of safe mode. normally it is just green. How can i get it back to normal and in working order. I already tested other...


your output of the amplifier have been distorted. I suggest you take this to a reputable service technician that has experience with lanzar OptiDrive old school Rockford Fosgate or Orion. These technicians are hard to come by nowadays but they definitely are worth the money that they charge. I happen to be one of those such technicians.

Jl 1000/1 amp not working w7 like it should


If you see smoke, it's virtually always the power supply transistors. There are several things that can cause it but sometimes, they simply fail. I will generally work with people who want to repair their own amplifiers but the this JL amplifier is complex and not always an easy amplifier to repair.

If you can't find a local repair shop to repair it, you'll have to go through an authorized JL retailer to have it repaired by JL.

Let me know if you have any other questions.

Protection mode on Lanzar Vibe 241


Almost without exception, if the protection light comes on as soon as you power it up, the output transistors are defective. Any reputable repair shop that services car audio equipment should be able to repair it.
