So TommyC let me know about a little device called the alpine power pack (p/n ktp-445) and I looked into it, put it on my x-mas list awhile back and completely forgot about it. Well got it for x-mas and just installed it, and wow it is nice! The only downside was finding a place to mount it. For now it is in my glove box but I think I will probably end up mounting it somewhere else when I find a place to put it. They are giving my JLs a nice new full sound to them. So I highly recommend it to any Alpine owners out there. It is around $100 online from a quick google search.
There is a crap load of wires on this thing FYI:

Add higher output and more dynamic response with this easy-to-install head unit power upgrade. The KTP-445 amplifies the head unit power output, resulting in a 150 percent power increase over the original power from the head unit’s built-in amplifier.
The KTP-445 connects any 2005 and newer Alpine head unit that has a black power harness.
I actually put this in my civic, 4 speakers and a basslink in there....
Yep, it amps the speakers and is all just plug in play, you unplug the harness from the HU, and this amp device just plugs in in between the HU and the harness.
I did some googling and looking on the car audio forums, they said all headunits will really only make about 20wx4 RMS if that. Also they said that these really don't make much of a difference, plus you can buy a real 4 channel alpine amp for $30 more.
I've been looking at this unit for about a year now...I installed an Alpine CDA-9886. It's essentially a speaker level amp. There isn't much out there that tells you that, but that's what I've gathered. Anyway, I was thinking of using the stock sat. receiver bracket as the mounting point (sits behind the glove box below the passenger airbag) since I took out the stock headunit. The only problem is getting the bracket out. The top bolt/nut combo is a real "peach" to get a tool on. Anyway, before I start to ramble, I though I'd give my two cents.
It is a royal pain in the butt to mount there, just an FYI. You will have to have one person inside the bed tightening the bolts and one getting dirty under the truck. holding the nuts.
Well this gave me a noticeable difference, didn't cost me anything and was simple to install, loved not having to run more wiring to my battery as this was in my civic so don't have a lot of room to work in that thing.
