all good info. matter of fact somewhere in here John himself states the same thing with the PBR amps driving J&M Rokker speakers. Not sure if it's the same model speakers as what you're running but I do recall John putting this in a thread somewhere.

 

I do.. LOL.. Love it!

 

I just had the same issue with my PBR300x2 last week with the Infinity 62.11s. The amp went into protection mode and stayed there. I had to turn the gains all the way down in order for it to NOT be in protect mode and start clipping. I ended up just taking the damn amp out and hooking the 62.11s to the JL amp that I have. Clipping solved...

I think it has a lot to do with the amp just no being able to take the power that those 2 ohms speakers demand. I could be wrong, but thats what I came up with. I am now putting that amp on the wifeys sportster and hooking up the Pioneer TS-D 6.5s to it. They are 4 ohm and should be fine for that PBR...we'll see..

 

I'm running that very same Set up R/F and J&M. And have no issues (wanting more BaSS LoL) with heating or clipping or protection mode. I Have been on many trips and not one issue. Now when I get home and Ride this evening it will SHUTdown on me !!

 

There is no way I could do that with my pn4.520 and polks. 4 to 5 bars occasionally 6 and I get real nervous. 5 bars though and it's rocking hard.

Thanks for the tips guys. I may try the rokkers again with the gains backed off. Going on a 150 mile ride tomorrow so should be a good test for the 7.1s

 

Update: done a nice ride today and the B/T's performed flawless. When we got back I tore into it again and hooked the Rokkers back up with the gains on the PBR turned all the way down. The amp went into protect mode again once we hit about 4 bars of volume. We then unhooked the tweeters and mids and it still done it. Next we unhooked the right speaker entirely and the system cranked just fine. Hook back up and unhook the left, immediately put amp in protect mode. So... a blown speaker on the right side appears to be the issue all along. Was able to get a call in to J&M before close and they are mailing me out a new speaker for replacement under warranty. Hope to see it in a couple days.

Looking back now I could have saved myself several trips under the lid had I just unplugged one speaker, rock it hard, then the other speaker and it probably would have tattle tailed on itself. Anyhow, lesson learned and hope to be back up rockin in a few days.

 

excellent troubleshooting sir and good news on finding your issues.
