burning smell from sub
ok so i have a visonic 1802a amp and a Rockford Fosgate p3sd410 sub which has the dual 4 ohm coils. i have my sub wired + to + and then to the + on the amp...and - to - to - on the amp so it is at 2 ohm (right?) and the sub is 300 watt rms and my amp puts out 600 watt rms at 2 ohm...i have the amp turned down to about 1/2 of its power. i have 8 ga wire for ground, power, every thing in the box and "monster cable" speaker wire which i think is 8 ga also but it doesnt say. now somtimes when i play my music pretty loud for a wile i start to smell a burning smell. it is a weird smell that i cant describe but then if i turn it off for a wile it goes away and doesnt come back till i have it up pretty loud....it doesnt sound weird and my stereo goes up to 40 and at like 25 (which is plenty loud enough to hurt ur ears) it will get the smell after like 30 mins of play time....the sub is only about 2 weeks old and it is my second one with this setup and my other one started to get a rattle sound when ever it was on...but i had my amp up all the way when that happened....so now i have it a little less than half way. any way just trying to figure out what the burning smell is. thanks

My 12" L5 use to do that, its a weird smell. It was my sub too not the amp. It did it any time I had it hitting really hard for to long at a time. I guess its the resin that holds the voice coil together getting to hot. It never seemed to cause any problems, I always just turned it down low so it could cool off when I smelt it.

even though your gain is turned down on your amp your still puting 600w to it. the gain just adjust the amount of volume put out. the sub will get the 600w still. i would wire your sub to 8 ohms and see if that helps. that should at least get the power down on the amp to were it should be. to do that you have to hook (-) of voice coil #2 to the (+) of voice coil #1. then take the other (+) and (-) and run those wires to the amp.
by playing it like you have you could have already blown the sub. so double check each voice coils ohm load. they should read anywhere between 4.2 and 3.6 ohms.
is it a mono or a 2channel amp that you have?
