So I have a pair of the Shelby Kicker 8" door subs going to a Cadence 300.2. The amp puts out 300 watts at 2 ohms. The subs are reading at about 2.9 ohms on my multimeter. I've checked and double checked all the wiring, and nothing I can find wrong there. The amp gets so hot that it just shuts off after about 30 minutes of playing.
