So recently I got my 99' D2 close to "perfect". I turned the radio on and noticed the front speakers were booming. I checked the Bass on the headunit and it was set to flat! What in the world? I thought my 2001 doesn't sound like that. My 99 window sticker shows it has a "320 watt sound system" and my front mids are tagged on the doors with H/K. I looked at the different amps at roverland parts. Mine was the XQK100210 model amp. Based on the prices I see online, I would think the XQK000050 would be the "nicer" amp due to the higher price. My 2001 doesn't show the H/K logo on the mids and the rear tweets say Philips. The other difference is my 99 has the spatial option under the settings. Based on what I'm seeing online and in my trucks, maybe this will help someone. I still have questions on the XQK000050 amp. Anybody have one? Here's my findings:

Your 01 doesn't have the spatial option? Is the Phillips logo you mention on the rear sticker of the tweets? I have a 99 / highline HK with the spatial and all of that, everything says HK on it - where did you find the model number of the amp?

It's strange - my friends 99 is ONE MONTH different than mine in production dates, yet it's totally different - the sunroof has a fixed shade (built into the glass) while mine has the split pull-visors that hook in place (front and rear sunroofs) there were a couple other things as well, theirs has the "99 SUV of the year" sticker on the rear windows which I've seen on a couple other '99 DIIs. This one also didn't have any cup holders on the center console, but those may have been added to mine before I bought it.

 

No spatial and yes it says Philips on the tweets of the 01. I got the numbers off the top of the amp and looked them up on roverlandparts.com.

 

It appears that the XQK000050 amp is for the sat nav option...
