Thought I blew my sdc2.5 on 1k daily. Amp cold, dust cap cold ??? Ended up being my shitty crimp on the quick disconnect melting. Swapped to wire nuts and bigger wire. Bass on!
The dust caps will always be cold on our woofers, we won't feel the heat. I guess there is a dust cap (or something else) underneath. Can't remember it's exact name
