My amps are running hot

[Lazyace1975 0]

Both my 1500D & 100.2 is getting hot under normal operation. Not so hot I can't touch 'em but pretty warm.

The 1500D is pushing my SS RL-p D2 at 1ohm & my 100.2 is pushing my comp set at 4ohms.

I run 1/0 wire to both & they are in an area where they should be getting a sufficient amount of air for cooling.

Is this normal or should I be concerned?

Thanks guys.

MY saz-1500d only generally gets warm when I push it, but it wasn't too bad even right after bass race. It was very warm, but that was with some clipping going on.

The heatsink being warm is normal, it's purpose is to dissipate heat into the air and it is doing that Only be concerned if it is extremely hot and you can barely touch it.

Thanks Jacob. Just wanted to be sure I wasn't hurting my amps.

To much invested in them for that.

Have a safe & happy Memorial Day weekend guys. Later

No problem!

Hoss' has been making his 1500Ds and 100.2s hot enough to cook eggs on since he first got them in August of 2006... and they are still going strong If you are running at a regular impedance and they aren't hot enough to go into protection, you are good to go. He is the guy with 8x 12" BMs in a truck if that rings a bell.

My 100.4 gets a little warm but both my 1500D's have yet to raise in temp. I was wondering how being surrounded by carpet was going to affect them but they are surpassing all my expectations.

The multi-channels will almost always run hotter due to their Class A/B construction. The thing with a Class A/B design is that it is always extremely inefficient at low power levels. Generally as low as 20-40% at lower to mid output levels up to a theoretical maximum of 75% (which is almost never achieved). I can get an SAX pretty hot on my test bench in a hurry if I want to, the SAZ-1500D, SAE-1000D, and SAZ-3000D take some work to get warm
