Built in HP Filter?

My $0.02
I'm thinking the drivers are dipping below 4-Ohms much more than expected, and overheating the amp. Hope this wasn't mentioned already, I didn't read every post.

Now that I've learned where to look for there spec's (which could be embellished) this amp is rated at 350 watts with a 2 Ohm load using the EIA watts per channel, 1 kHz, 1% THD criteria. However with the condition of the thermal compound and the quiet fan, dipping low certainly could not have helped the situation.

To quickly summarize this thread the amp now works fine.
Down the line I may tinker with it some more but for now I'm good.

To quickly summarize this thread the amp now works fine.

An update to the summary is that I got the strain relief from Walter's
Carver to go on some 14 AWG conductor and stabbed it back into the hole.

I was kind of lazy about it and simply wire nutted the old to the new.
I didn't want to take it apart to solder in the new.

The 14' of 14 ga replaced 4-1/2' of 18 ga and probably 15' of 16 ga extension cord.

... and now I use that for those subs. No fan. Quiet.

I have a different strain relief solution but this works for now ... probably for ever.
