My 2nd JBL MS-8 goes into protect mode? Any help

[npcout 10+ year member]

This is my 2nd MS-8 that has tanked in less than a year. The first unit went into protect mode 9 months after install. I contacted JBL who said it is not fixable and they replaced it for free. Now after a few months, my new one went into protect mode. Again jbl said it cant be fixed.

SETUP: OEM Headunit to the ms-8, which goes to a 4 channel amp and mono amp.

THE PROBLEM: I turn the car on, and within 5-30 seconds it goes into protect mode. Per jbl who was quick to say, the issue can't be fixed.

Does anyone have any suggestions?

Sounds like your not setting it up properly. I have had mine for a couple years with no issues.

I'm not familiar with ms-8. but check this-

What is your typical DC voltage your vehicle is seeing while on? Are you running externally regulated?

What OS does the MS-8 run on?
