I'm thinking that ur amp wire isn't a big enough gauge to take the consuption of the amp. And plus you could do what i've done.. run ur wire from ur battery back to a compasitor. Remember every 1000 watts is equal to 1 fared. Example 2500 watts = 2.5 fared. With this you will never have amp shutoff or dimming of interior or exterior lights.
Forgive me...I havent' read anybody elses post.
If your Alpine Subwoofer is Dual Voice Coil (DVC) then you MUST MAKE SURE IT'S RUN IN SERIES!!!!!
Bridged amps these days can only take a 4ohm load when bridged. That's it..final..done. You're lucky your amp has a shut off. If you don't have a DVC Sub we'll have to speculate some more.
Here's a diagram to help

Nope. Love the illustrations, but they don't really cover his setup. He should use both sides of the 2 channel amp. I suppose he could series the coils to the amp in bridge mode and get the same results. However, channeling each coil seems more natural, bypasses a couple of circuits inside the amp for a cleaner sound, and lets the natural impedance of the VC's compensate any manufacturing variances inside the amp. Plus the wires going to the coils carry less current individually, which is a plus, if like most people your just using 10-12 ga. for the speakers.
I forgot about the12volt com, haven't been there in ages.

I'll admit...I didn't expect RMS handling to be that low...but that's what setting gains properly are for
Majority of sub freq's can handle up to 10-15% distortion before an individual readily notices. Channel separation and "clean" amps aren't as big of a deal. That's why SQ oriented installs don't focus on the subs as much.
16awg wire is all he needs...not sure what he's running? I probably missed it in his post.

I'm of the opinion that caps don't help anything :/

well the type r are all dual voice coils but they made a dual 2 and dual 4 if its dual 2 you want to series the coils aka run a jumper from positive of one coil to the neg of another and run that to your amp ... or just take the amp back and buy a mono block and that should solve all your problems . The type r is a very good sub and try to buy the little alpine mrp-500 its only about 200 bucks and works great with the type r if its a dual 4 . but if its dual 2 ohm stick with the 2 channel you got
OP...was this ever resolved?
Quick summation...
Equipment
1)Dual Voice Coil Subwoofer
2)Two channel Pioneer amp
Fix
Bridge the amp and run the coils in series.
Reason
The Pioneer amp is stable at 4ohm when bridged. The Voice coils MUST be run in tandem. Meaning they must receive the same signal or else you'll jack up your sub [refer here: http:]//electronics.howstuffworks.com/speaker5.htm
Therefore, you must run the coils off the same channel. To get the most out of your Pioneer amp you would need to bridge the channels. BUT!!! You're Pioneer isn't stable below 4ohms when bridged. That's why you must run the voice coil in series. [refer here: Subwoofer Wiring Diagrams, One 2 ohm Dual Voice Coil (DVC) Speaker]
