Check the incorporated capacitors (if any), also inspect the braid speaker wire on the bass speakers (i understand that these are cutting out).

The braid wires are located between the speaker connection terminal and the speaker cone - if these are damaged or broken, this can cause the speaker to cut out intermittently. To see if this is the case, try to push the speaker membrane gently inward when the speaker cuts out - if it momentarily regains function, then the braid is almost certainly damaged.

Braid wires can be resoldered, but it's not a very easy task because of the structure of the braid, which makes it difficult to clean and solder.

You should have it repaired by someone with good soldering skills or at a speaker repair shop, otherwise the alternative is to replace the speaker.

Your speaker is an active one. This means that it has indepented amplifier for low and high frequencies. So maybe the woofer (low speaker) is still active but its amplifier is defective. In order to make things more clear take a look at this block diagram to understand the signal flow:

I suggest you to unscrew the screws at the back panel and eject the whole electronics from the inside:

Take care the cables that connect the electronics with the speakers. If it's easy mark what goes where and unplug these cables. Now with the electronics on the table try to locate fuse(s) that may have been blown; since you don't smell burned components, fuses is the most common problem. Replace any blown fuse with the same one and put things back in the proper order. In case that you don't locate any fuses the problem is at components and I can't be sure if you can manage replacing components.

In case of a problem or clarification, don't hesitate to post me a reply before rejecting my answer.
If you are satisfied, accept my solution.

Thanks and regards

No more subs in jbl prx-512m


First check the speaker with a multimeter.

If it is OK, then check/repair the Class D amp that drives the speaker,

up to the input stage.


There are board part numbers printed on the PCB and some are

available on line.

Have a tech to guide you ,should you feel to Diy.

Jbl 635 over heating and shutting down in the middle of your gig needs 20 mins before reset ans shuts down again


I had same issue with the series below (525). I removed the amp and there was an aluminum inside cover I took off the amp that was secured by a single top and single bolt/nut combo. This was holding in all the heat but also perhaps to physically dampen potential vibration of some of the components. I got mine to cool down 10c less than one with the manufacturer's case left intact (unaffected speaker) and it quit cutting out on me without having to devise a complex fan. Hopefully this is true for the PRX 600 series as well.

I have a pair of jbl 512m speakers one is louder than the other one but it works


Make sure your audio interconnecting cables are XLR or TRS balanced lines. Use of TS cables similar to guitar cables with only two conductors (only the tip and the sleeve) reduce the gain 6 DB and contribute to hum and noise.
