Kenwood Excelon KDC-X997 has nice features and 3Pre 4.0V @ 600Ω and now the successor of the KDX-X996, while checking; some had the older 996 more than the new 997. Serious $200 -$240 tops is money well spent, I have seen it at $180 four different retailers remembering this a flagship line for KENWOOD, pricing as to the end user, you can vary and be patient you can get this nice unit average cost $200 and worth the price. That is if you like true HD 2.1, 2.2, 5.1, 5.2 any higher is pure waste, all BS of 7.2 or 7.1 as a car audio is what so you can say wow look at me, I have 7.2 but need Viagra. I will put my 2.2 audio HD sound system against any higher and certainly smoke any BS 7. Foolish surrounded by stupidity system offered OEM or aftermarket and it’s in a 92 SL AMG that does 209mph with great sound beat as I pass Germans on the autobahn at 180mph, all speakers are placed in the cabin, no subs in trunk, including both Subs are not flat styled and tuned vented. All 6 PW amps, one preamp are against metal plate separating fuel cell, two fresh outside filtered air vents with HC low speed fans, I do not use KENWOOD in this car, its a modified ALPINE, I post some pics in my profile. But back to a great unit meeting your 3Pre this is the one right at 200 buck if you.re not patient. $180, 30 to 45 days you'll see it 160 150, sure of it, stuff that sits on a shelf is a huge motivator to a retail outlet to get rid of it, the next new one is not far behind.
