Default Blown Rear Left Speaker

Iím at a loss I had my local bike shop install both front & rear Rockford kits on my 2018 Road Glide Special. The head unit was flashed as recommended. The bike has been on the road since April and has blown the rear left speaker twice. Bass on the head unit is set right in the middle & Treble is set 2 higher than middle setting.

I have maybe had the volume up between 1/2 & 3/4

Any suggestions what may be causing the issue. The shop that installed my system has done many of these kits with no other complaints.

Thanks,
Pete

What are the amp settings? I'd start there. RF has recommended settings for the amp. I'd check and see if it's even close.

Also, who did the flash and was it the correct flash? It is my understanding that there are 4 different options for the HD tech to flash and if they chose the wrong one it could cause issues.

start with this. I turned my RF amp down compared to what RF recommended after I blew a speaker the first day.

Thanks for the replies. I pulled the amp yesterday & adjusted the settings to less what RF recommended. Hopefully that solves the problem. The flash flattened out the head unit eq & added fade ability

Just a follow-up in here. Rockford Fosgate did revise its amplifier setup recommendations based on the number of users that are driving their system at full output and blowing-up speakers. You can find the summary here:

Funny I am reading this post. Today I noticed my left rear was toast. Is there any kind of factory warranty on the speakers? I had my kit installed at the Myrtle Beach rally May 2018.
