hot amp... why?

[timmyjimmy5150 10+ year member]

Okay...

I have a JL 450/4 amp pushing 4 sets of component speakers in my F-150 truck. The amp is located under the rear bench.....

Today, I had the radio turned up pretty loud --- probably 3/4 the way up..... I started to smell a "hot" electrical type smell from the rear of the truck........ I turned the radio down and later felt the amp --- It was very hot.

What causes this? Is it lack of air movement or something wired incorrectly? Please help with any advice.

More than likely the amp is not getting enough air across it to keep it cool.

Could be a combination of things, lack of ventilation, improper gain settings etc... What size wire you're running?

Running it hard = heat

Not enough air flow = heat

Try hooking up a fan to cool it down.

I just don't understand? My friend has the same truck as me and the same amp.....The amp is even located in the same spot..... He can run his system loud all day and his JL barely breaks a sweat.... Mine is red hot.....

Is it maybe impedance? Oh -- and he doesn't have a fan either

Are your gains set "properly"? maybe its time to re-check

Any update?

Not exactly sure about the gains......

I had a shop install the amp.....

Hmm...that might be the problem(shop) Can you get someone u know to check it for ya? it's not hard at all to do it your self. Read the sticky at the top of this forum section. I would def ask a second opinion about your gains settings.
