My roomate has a GMC Jimmy and his sub box sometimes smells like rubber/plasticy when its pushing. He said that it smoked once. He just got a new deck, and when he had the stock deck on it, it would only smell when it was really working hard. With his new deck it sounds fine, its just the smell that is a problem. Does anyone have any idea what is causing this?
i would say it's probably in your head or something else causing it
but what is his setup like?
only thing a new deck would change is the distortion level would decrease

Its probably moving some smelly air from in the back up to the front.

Solution: Unscrew the speaker, stick hand in box, remove old dead smelly fish your friend put in as a gag, throw in a box of armor all and spray febreeze, screw speaker back together, turn stereo up loud... problem solved.

A. The smell is from the sealant inside the box.
B. One of the subs has a damaged coil and is burning.
C. One sub is already blown and the other one is on its way out.
You cant really tell when a bandpass sub system is working 100% efficiently. 1 could be blown and is working against the other one, both move from the air inside the box. Just take it apart and check whats wrong, if anything at all.

how old/new is the sub? how many subs?
some subs have a burnt kinda plastic smell to them when they are warmed up or pounding...some times a problem sometimes it isnt...
like it was mentioned, in a BP box it is very hard to hear distortion since the design masks it...but the VC could be burning up from it...
smoking subs are very bad...and are more then likely damaged...
i would definately take the sub out and visually inspect it for any signs of damage...apply a little bit of even pressure on the cone to mimic excursion and see if it squeeks or sratches...<---bad sign...blown VC...
if the sub is DVC then wire the voice coils up separately and check the resistance across them one at a time...(unbridge the amp so you dont smoke the sub with crazy power though..) see if both coils work properly..
i had a DVC in a BP box once and it smoked and stunk like a SOB...i took it in and they said i had blow one of the coils...the other was still working fine for the time being..:shrug:
either way it can hurt to look at it...

yea sounds like 1 is blown and the outher is woukin to hard. thats y i never liked bandpass boxes cause the run off the same airspace. i like mine to run in sepret airspace so i dont have that prob
Noting in my system is blown and when I push it hard it begins to smell like band-aids in the car. Yes that is weird but thats what it smells like. haha
could be the same " rubber/plasticy" smell
