Do you have single voice coil, if its wired down to 2 ohms this may explain. What are the voice coils? Single 4 ohms, or duel 4 ohms, or duel 2 ohms?
657 watts RMS x 1 channel at 2 ohms,

Right, but if you have 2 subs the ohms will be 2 ohms

yeah i knew that.. but they arent bridged... i have 4 speaker terminals... (+)(-)(+)(-) and with all four wires in that should be four ohms... thats what the guy at best buy told me... he said if i twisted the wire and put it in one pos and one neg that then it would be running at at 2 ohms

dude that amp does 400wrms at 1 channel bridged, so if your running one sub to each channel at 4ohms your subs are only seeing maybe 100wrms each. so the smell is probally the VC getting hot from the amp clipping.

i got funny smell, when the wires melting when they get too hot, when the speaker getting way too much power, or plastic or sumthin else burning.
i make sure not to keep sub up oud continuosly, and i have much thicker wire to every thing eccept RMT.

If they are brand new, its not uncommon to have a weird smell. It might just be the subwoofer naturally burning off the glue that is on the voice coil...

first off that amp is seeing a 2 ohm load if your running 2 4ohm speakers on it, it is internally bridging the speakers, the 2 sets of terminals just makes it easier to wire., your sending more then rms to them subs.

This is the amps specs; 657 watts RMS x 1 channel at 2 ohms / 2
Thats what ive been trying to tell you. Each sub is seeing ~ 353.5 wrms each....No wonder you smell burning. Did you look at the link I sent you? Regardless of sales mans rambles, those subs present either a 2 or 8 ohm load no matter how you wire em.

ya ur running a 2 ohm load with those subs then. what rms are the subs?

if the subs are 350rms ones, then they are wired fine.

When I had my premier SPL 12's, I had a horrid smell come from them that I wasn't able to locate before I traded off the car. I just figured it was the amp getting to hot on the back of the seat, or the speakers heating up the glue on the boxes.

lol why would that matter. a sub can take more rms that it is. some can even take 2 or 3 times there rms like a treo...so what the hell are you talking about.

i think your amplifier is clippin, when aplifiers clip send a dangerous signal to your subs and gettin damaged, and make sure u got good ported box, the box can estress the woofer too, do the big 3, or replace your altenator and check your gains, cables and ground

my amp has a clip light on it.. and the manual says the clip light is supposed to blink when it hits the highs of the music... but not to stay on constantly.. and mine is jus blinking on the high points of the music. and what norris said.. my gain is only HALF... its really thr getting like 170 or sumting like that.. and my box is sealed... its in an f150 and with about .55 cu ft... we didnt really have many options on box building.... i do also have another amp in my truck its an alpine v-power for the infinity kappa door speakers.. would taht amp make a differece onthe subs performance.. they arent linked together they are jus run to the battery sepperatly... idk...

Its a mono amp. there are 2 sets of terminals for eaisier wire configs, but it is bridged on the inside. Mono, 1 channel. Personally, I bought a new infinity four channel, used it for a day and then returned it. Was not happy with its performance. and the clip light did just blink on high notes.
And Norris, I didnt say putting more rms into a sub was bad,Provided it is a good quality sub/amp combo. I am just giving amp/sub specs. I would be weary putting rated rms into any Pioneer, ecspecialy with a high distortion amp like Infinity.
Chase, did you try to wire em up at 8 ohms just to see if the smell goes away?

i cant wire it at 8 ohms. they are in seperate boxes underneath the rear seats. so it would be hard to wire it correctly... would it be easier jus to buy a premier amp thats the rms of both together at 2 ohms jus to get the worry out of the way???
