So you're not running the tweeters off the amp and connecting direct to the head unit? Will you run all the wiring through the raceway on the drivers side sill?

A better head unit would be nice, door and dash speakers are original and work fine.
Yes, thats the biggest hurdle to overcome with convertibles for sure!

And 200,000 color choices for the display and buttons let you match perfectly to the interior.

I'm sure your custom install will sound fine with the Kenwood - but the Pioneer app and the plug-and-play of the Pioneer was worth the $100 spend.
When I purchased this Kenwood KMM-BT322U, the Pioneer MVH-S512BS was not available yet. I don't really need many features, I do like the simple design with symmetrical layout, 6ch preout is a must, DTA is a must, adjustable illumination is a must and BT is a must. Kenwood fell right in. With that said, and now I've had it for over 6 months - NOT a unit I would recommend. Integration with Windows phone or Android phones is very very unstable. It does however, control Spotify and Pandora perfectly well, DTA is perfect. Night illumination is spot on with Orange1 and fairly easy to see during the day.

Now that these Pioneers are out, flat, simple layout, has all the features I needed and more, If I had to do it allover again, I would deviate from Kenwood for sure (would be the first time in many many years)

Those Focal tweeters will indeed be running of that 5-channel amp via 2 way supplied x-over, other 2 channels to rear 6x9 and last mono channel to 10" sub. My current tweeters (temporary old Bostons) are running off the head unit only, and small mono amp is powering the Acoustimass bass driver in the factory Bose enclosure, basically same speaker as factory, just 4 ohm instead of factory 2 ohm (if I remember correctly). I just didn't want to stress the little amp

Identical drivers

And analog bass control for now in this compartment (but will be relocated to the center console ashtray

A little progress today, rear speakers are fitted!

Under mounted them

Covered the grill inserts with grill cloth

I had to modify some of the mounting points of these custom grills, but well worth it. Low profile, all metal, very sturdy, painted the outer frame mate black

Overall, very happy with the look and fit

Do we know the largest size speaker that will fit in the rear? Like a small two-way?

By my measurements under 2.8" in overall diameter. On SL320 I used Dayton Audio Reference drivers throughout, rears are RS75-4, these are 2.83" overall diameter and you can see here that it is "max" and that is with trimming frame few millimeters. Mounting depth is very VERY restrictive as well https://www.benzworld.org/forums/r12...l#post15560817

To make these Dayton driver's a true 2-way rear fill, I've added a pair of tweeters at the corners just above the factory drivers and both covered both in matching grill cloth
