I was on my way to the river when all the sudden my bass control **** light shut off after 1 hour of driving, I took it to an audio shop and he told a capacitor would help the amp from not using as much power, thus overheating.

any other suggestions

 

How high is your gain? What kind of amp is it? What is the sub and the specs of the sub and amp.

 

You don't need a cap. You need better ventilation or a fan.

 

I had an old Alpine 3554 amp that started overheating, right before it went tu. Usually excessive heat indicates a transistor is going bad or something. That said, some amps just run hot. You could try installing a little fan over it to get the air circulating over the heat sink ridges. I had to do this to an old Fosgate amp I had in my '66 Bronco. They are cheap and don't make enough noise to notice. It sucks when you are bumpin and your amp cuts out 'cause of overheating.

 

All great suggestions, but hard to diagnose without knowing where the amp is located.

If this is the only amp in the truck, no CAP is needed. A fan may not be needed pending where it is located and even that, how much of the gain is up. If you are over driving, then yes, it will go in to protect mode.

Can you give us more specs on where, what, blah blah blah?

BTW, Family Force 5 has some wicked bass in it....turn your amp down is a good guess.

 

im gonna have to say that a cap isnt going to help at all. if its a heat problem find a way to ventilate, if its a power shortage, then add a second battery, do the big three upgrade, and look into a new alternator with higher output.
