Question about JBL Car Audio & Video
Posted by Anonymous on
Hi, Looks your amp has gone into "protect" mode, the first thing I would check is the fuse, should be under the bonnet (hood) about 15 cm's (6" or so) from the battery. I've found a couple of sites that may be able to help with your problem.

it seems rather redundant to bridge a mono amp. Unless the instruction manual states otherwise, i would assume that one speaker output is identical to the other (ran in parallel, like an A or B speaker, not like Left or Right), and you would present the amp with a two ohm load by wiring one speaker to each output. Bridging it may or may not work, but, again, it just seems redundant.

It probably has shorted output transistors. To eliminate other possible causes, read through the following page.

Let me know if you have any other questions.

It's rare that 2 channels will fail simultaneously, are you sending 4 signals to the amp or just 2?
If you are sending just 2, perhaps the problem lies before the amp in the cabling to it, or the output from the headunit. If you are sending 4 signals then there may be a fuse in the amp that drives 2 channels out of the 4. Of course this may be the case should you just be sending 2 signals.

Check the voltage at the amp. It's possible that the voltage is either too high (above 16V) or too low (below 8.5V). Also make sure that the amp case is not grounded. If these check out OK, the most likely cause is that the amp itself is defective and requires service.
Hope this helps.
