No but I plan on buying one very soon

Good idea. Once you do you'll know exacty where it's clipping at and it'll probably help with the sub heating up so much

Do yours ever get hot. I have mine on 1.5k an it heats up the dust cap alot

you got issues brah, 4in coil getting hot on 1.5k is a FEAT. clipping, distortion, something is going on.

and if you have to ask, dont do it. it is rated for 2500wrms, run it at 2500wrms or less.

Thank you. I didn't want to be the first to say it but somethings is really wrong there. The old UFO BTL's with a 3" coil can take twice what your putting to that sp4 all day and not get hot.

I though it was common for a speaker to get warm. Heat is heat. I believe the high temperature is playn a role. My car is park in the sun basically all day. I just played my system for about a hour an it barely got warm. But I will purchase dd-1

all speakers gain heat and warm up, BUT the surface area of the coil is there to dissipate the heat and cool the coil along with pole vents/pole plugs, etc. The sub is built to cool down as fast or almost as fast as it heats up. a 4in coil should take 4k thermally all day on a clean signal, possibly more. I feed 3in coils 2-3500rms clean and they dont even get warm, not a clamped number so... you know.

edit, beginning of summer, houston texas, 102 degrees, 111 in my truck, ripped on a level 5 (3in 8 layer) for 20 minutes straight on 3k, barely warm after, btw no AC either.

Edited for whatever the hell that rambling drunk jibberish I typed last night.

OP, I'd just hold off on adjusting things until you pickup that DD1 or scope.
