Every Kenwood amp I've seen in the last 5 years (about 5-6) goes into Thermal
Protection after 6-7 songs at very high volume . Coincedence , I think not . Korean made junk? I think so .

Check out some of the 3 or 4'' computer fans. They run off 12v DC

no fan will help you if you cant get the air to pass by the heat sinks.....trim out the foam so your amp doesnt touch the seat and you will be fine without fans....

I'm working on upgrading my speakers and 2-ch amp, but have been running the same Kenwood for over a year now. It's a few levels down from yours (and much older) --- the KAC 7204. I haven't had any issues with it. I've taken numerous four/five hours drives as of late and run it pretty hard. It doesn't shut down on me. I agree with a few of the others--sounds like an issue with the amp itself.

I believe I may have found the issue, the power wire was loose in its terminal at the battery, but not due to a bad crimp. It seemed to have corroded - when I pulled it out, fine sand (I assume the metal of the wire) and some intact strands almost poured out of the end of the connector. I cut about 1/2" back on the wire and then stripped off a 1/4" and put nice shiny new wire in a new ring terminal and hooked it up and have had zero problems since, and I ran it very hard for about an hour continuous yesterday.

That wire had been in there for a year, guess I shouldn't expect much more from $1.50/ft 4 awg from the local shop...

Hi Chris.

When ya get a chance, you may want to go over all yer connections, and take the time to tin them with solder, and then solder the wire to the ring terminal(s). This helps keep the corrosive influence of the air at bay.

Good luck sir - and thanks fer posting that

I used to listen to 128-131 DB daily for hours, I have yet to notice any hearing loss.

Growing up, my dad regularly hit 110-120 DB.

Thats on a high quality sound meter too, and also louder than a jet taking off.

Not trying to start an argument because I could care less, but that's not a claim you can make. Hearing loss would be so gradual you wouldn't notice it. Not to mention that you can't hear from other people's perspectives, only your own. The only way to tell would be to get your hearing tested several times throughout your life.

its ok, I know you are just saying.

Last time I had a physical after having that car, AND after working underground for a few months, I have near prefect hearing, but I never had perfect hearing to start with.

I had a physical before working in the mines, and one for my current job, I am pretty sure I came out the same on both tests.
