So I just bought an Alpine Type-R 12" sub (dual 4 ohms). I had it wired at 4 ohms initially, because I was trying to "break it in" like I was told over and over. I wired it down to 2 ohms after a few weeks to get the full power, and after a few days, it took a shit. I'm not quite sure why. The wiring was done professionally too. My amp (Alpine MRP M500), is essentially perfect for the sub, and the box was 1.94 cubes (recommended is 1.0 - 2.0). I don't know what happened. So if anyone might have an idea why, I'd GREATLY appreciate it. This was my first sub; I'm 16, and I can't go out and buy a new one whenever I like. And this is off topic, but it's a big concern as well. I bought it from sonic electronicx, just because of the price. They say they don't replace blown subs. But the thing is, I didn't overpower it or anything, and it took a crap on me. Will they replace it? I was reading some of their forums, and the guys were saying they've had theirs replaced everytime, even when they were negligent with it. Anyone with experience from this website know what they'll do? Again thanks in advance. I'm really stressed about this.

If one's amp would be clipping, resulting in a blown sub, is it a permanent issue? Or does the gain, bass eq, and other filters need to be tuned to insure that it won't happen with the new sub?

It's a dual 4 ohm sub bro.

I had it at 4 ohms (using both coils). If it was wired at one ohm, does that do something bad to the sub, only incorporating one coil? Anyways, the clipping...is my amp ruined, now that the sub is? Or do I just need to go somewhere else to have the amp tuned when I get a new sub?

Jeesh, that's more than I knew by a long shot. My gain was on "nominal". It stunk like crazy (like a burning paint type smell). The sub grinds when it plays mainly. I applied the even pressure yesterday and it grinded.

So my subwoofer (Alpine Type R 12") is dual voice coil 4 ohm. Now what I'm confused with is it's wiring down to 2 ohms (for 500 watts RMS). I wired down to "2 ohms", but is that per voice coil, making it 4 ohms, thus leaving me with only 300 watts RMS? If so, does that mean I'd have to wire it down to 1 ohm, making it 2 ohm total? Basically what I'm asking is if the ohms are per voice coil, or total. Any help would be great! This would really make things clear.

I have an Alpine 12" Type-R 1242D subwoofer and I'm currently looking at an Alpine MRP M500 amplifier. The sub puts out 500 watts RMS (dual voice coil, 4 ohms), and the amp puts out 500 watts at 2 ohms. First, how do I bring the sub down to 2 ohms, like people say they do? Also, does the amp need to be more powerful? After measuring the power it can put out specifically, it came to around 600 watts. Is that too low or too high? I'm looking for a good, deep bass, mainly for rap, just for reference.

Thanks for the help man.

Well that's awesome, thanks. Could you link me to a good wiring kit?
