Algiht by buddy had his system for about 1 year now and he just started having problems with it, his system was installed by a local Vision's shop so it was installed right... i think.

Anyway, he had a Alpine type S 1242D so it's a dual 4 ohm, he still has the amp and it's the kicker ZX300.1 (2007 modle) so it was hooked up to run at 2 ohms, one day he was driving and he smelt something and thought it was something else, kept driving and playing the sub and amp and before he knew it his sub was blowen and there was no sound coming out of it. then i tols him to get a Rockford Fosgate P2D412 considering that the amp is over powering the sub a little bit, i hooked it up and a week later he said he could smell it again. i have no idea what it is.

PLEASE HELP, any info is very much appreciated, thanks.
Bryce.
