JL 300.2 running hot

[icnivad]

Hey, I have a JL 300.2 that seems to be running hotter than I would expect. It's not enough that I can't hold my hand on it for longer than a few seconds without having to pull away. Otherwise it seems to be working fine. I am pushing 8 6x9s with it wired into a 4 ohm configuration. It runs hot even when we're not pushing the volume particularly high.

Is this normal for this amp?

is it in your trunk? the heat will make the metal surface hot

it is not in the truck. This is mounted to the wall of my bus. near the driver seat. There should be plenty of circulation.

Pics of this bus and install?

How's your voltage?

 

[icnivad]

I don't have any pics on me. They are powering off a deep cycle battery. I think the voltage was around 13.5

You need to measure the voltage while playing the amp at your normal

listening levels.

Get some pics too, I'm curious.

 

[icnivad]

ok. What am I looking for while measuring the voltage?

Under 12v sporadically.

How would that make the unit run hot? If it's not getting enough power, wouldn't it run colder than normal?

my JL seems to run hot too, i mean to the point where i can barley touch it, I have an e4300. It only seems to do it when im pushing it for a while, a 6.5 inch component set and 8inch woofer. You may also be asking a bit out of it with 8 speakers hooked up to it. try running 4 or 2 and see if temps stay the same or get lower, with the same 4ohm load of course.
