That's the setup I have... It's powered by a JL Audio XD 300/1. The output is spectacular without knocking the doors off. I had it professionally installed for $250. After the install, I checked things out and it's actually quite an easy install as the battery is in the rear and the access to the wires for the HK amp are right in the back as well. Probably took them 90 minutes to do the whole thing.

I see you PM'd me, but I thought I'd share this as it may help others. Looking at the install, it seems they tapped the purple and yellow wires from the HK amp (no idea what speakers they lead to, however). I installed a line driver to improve the signal from the stock amp as it was a bit low (cost $100). Additionally, they used a fuse tap, which runs across the spare tire well where the batteries are held, to act as a a power on source. The setup is clean and easily accessible.
