Earlier today I had it bumping pretty hard for roughly 25 min down the highway and upon returning home I went back to check on all the hardware. The amp was burning hot to the touch with a decently strong burnt smell all throughout the trunk, the sub's cone and dust cap were also hot to the touch and I'd imagine the magnet/coils etc. probably were too although I didn't check. Question is, did I do something wrong when pairing these two? I have seen most reviews say this particular amp usually runs very cool and it's specifically advertised as capable of running a sub at 1 ohm, additionally the sub's max rated wattage is barely equal to the amps RMS rating so I don't believe the sub's overpowering the amp. I would prefer to keep the 1 ohm setup as the bass is amazing but also don't want to risk catching on fire in the middle of the road lol, any help is appreciated.

You can also get a two sub box to match that amp, that gets way louder. |

Also setup your subsonic filter on the amp, that can save power. |
