Overheating

[jLblazer620 10+ year member]

I just got a jl audio 1000/1 the other day and hooked it up to a 13w7. When I turn it up loud and run it for a while the amp gets very hot. Is this normal for these amps or is something wrong?

How and where is the amp mounted?

Right now its just sitting on the carpet flat, i didn't mount it yet.

It will get alittle hotter when run off lower voltage, so long as it stays under 85celcius it should be fine.

I dont know how hot 85 celcius is though lol. I have the amp hooked up to a 5 farad cap. You would think that would keep the voltage at a nice level, ya know?

A cap won't help voltage at all just current, the size of the battery and alternator will determin you're voltage under heavy load. Check the DC voltage at the battery terminals with a DMM when the system is bumping to see how low you're voltage is dipping, 14 volts with dips down to 11 while the engine is running is normal anything below 11 volts hints that a stronger alternator may be needed.

A DMM is a digital multimeter(if you didn't know).

The amp getting hot wouldn't have anything to do with a bad ground connection would it?

what size power gauge you have going into the amp....?

 

[jLblazer620 10+ year member]

4 gauge going in and 4 gauge going out. Jl audio 1000/1's only accept 4 gauge.

are you sure it's wired correctly??

 

[jLblazer620 10+ year member]

Power goes to cap then to amp. Cap and amp both are grounded. Would bad wiring cause the amp to get hot? I mean it runs fine and the power flows right through it.

It doesn't get hot until i turn up the volume and get the bass really bumpin' but that amp should be able to handle anything.... I just wanted to make sure the heat was normal.

my amp gets hot to the point that you'll burn yourself if you touch it... still runs fine

 

[jLblazer620 10+ year member]

Well if it could be because of bad wiring can someone let me know because I don't want to damage the amp.

I think you're worrying too much, if the amp is working fine and not cutting out then everything is OK.

That amp will have a thermal protection circuit in it that will shut down the amp as soon as it gets too hot, since you have not mentioned anything about it going into thermal protection I assume it must be running within specifications.
