ALWAYS IN LUDICROUS MODE! P90D>P100D Upgrade
I went with REUS. Very Very nice. No issues. They came to Hawaii for install. Give them a call and see when they might be in DC area next. They travel all over the place.
If you plan to go all out, then I'm certain the Reus and @Dickerns suggested would probably be best, but for the $ I don't think you can do better than the LH, especially considering there's no wiring modifications when you do the LH option.
BTW I'm not affiliated with them in any way (as you can see on the 59 page thread, I'm constantly lambasting them)
Cliff @ Reus is coming to the DC metro area in January. Call him, or PM me and I'll put you in touch with him. Cliff goes over and beyond for his customers.
What system did they install for you? I've heard people rave about Reus, but I have yet to see the specific details about their systems.
I'd also recommend Reus, like you I drove around with the factory HiFi audio to get a baseline then went for the upgrade, I'm quite happy with the the result. I would definitely call it an audiophile level upgrade!! I went with what they call the 2.5 system it uses most of the components of there high end 3 system, and is basically just lacking the 2nd sub and extra amp for it. As it stands the 2.5 system has more then enough bass to overpower the system with the sub knob turned all the way otherwise it's quite ballenced. One of the other benefits of Reus is there willing to migrate your system to another car for just labor cost and possibly travel costs in your case...
