All i know is when it went, there was something rattling inside the sub(when bass should be coming out, not something loose without the bass but something rattling when the sub should be pounding...), and when I unscrewed it and took the sub out of the box... damn there was a lot of smoke... Now, if i were to push in the sub and let it come back out, its reallly really rough and doesnt go in much.

Honestly I dont want something to big. But im not sure what to big would look like. Its going in a 2003 Eclipse so the hatch should make the sub a little louder than the tradional sedan. I like loud bass but dont want to replace the entire system, just the blown sub. I'm not sure what sub would be best and I def. dont know what size box to use, nor sealed or ported. With my old type r in, I had plenty of room for a bigger box. Because I valued my money, I never put anything in my trunk/hatch. So I guess whatever you think would sound the best. Your the experts thats what im looking for...

Ok. So from what I've read on here is that a loudish sounding sub for my 1000watt amp would be the 12" Q in a ported box, at about 2 cuft.

Ok. So i just read that the Alpine CDA-9857 has 3 x preouts . So your saying the gain should be matched to that being '3' . I love how I paid Tweeter to install the entire system. Ended up costing $1,038.71 for the install and wiring and Ipod wire and that crap. And they can't even set it right. And for the new sub issue. I was edging toward the 12" Q. But I don't have any professional knowledge of any of them. With the 1000watt amp and most likely a sealed box, i'm guessing on what i've read that the Q would sound 'louder' in bass.

The Type R is 4 ohms. When the Alpine MRD-M1005 operates with a 4 ohm sub it powers it with 500 Watts. Thats as far a I know.

My current box was made custom from Tweeter for the Alpine Type R 12". The box is a single layer MDF box. If I were to get the SSD being the lower model i'm assuming it would work. If I were to get the 12" Q, would that need a double layer of MDF on the front of the box? The box I have is 1.2 cuft.

Yeah I have no idea what did it. I have a complete alpine system. I have Alpine Type R component speakers, Type R 6x9's the Alpine 4 channel MRV-F345 amp the Alpine MRD-M1005 amp, the alpine CDA-9857 headunit and the 12" type R. I figured they would all work well together. Obviously not. The only thing I could think of that would have blown the sub would be overpowering it with the gain up to high. But the gain is set to .7 out of a possible 8. So i'm not sure and I don't know to much about this stuff anyways to diagnos the problem. When it blew, I was listening to my Ipod at volume 25 out of a possible 35 and the bass was working fine. I pushed the next button and I'm Shinin' (a bass song) came on, but not one note a bass came from the sub. I dunno what happened.. It sucks...
