Well let me start out by describing the system:
05 Mazda3 hatch

HU - Alpine IDA-X001
DSP - Alpine PXA-H701 / C701 combo
Amp-1 - JL 300/2 front stage
Front stage - CDT M6 / US-200 / DRT 25/26
M6-front doors, DRT-25 - Kicks in front of the m6 angled toward dome light, DRT-26 way foward in A-pillar 45 degree angle toward windshield

Amp-2 - JL A2150
Rear fill - CDT HD-62 / Memphis mclass tweet combo
HD-6 in doors, mclass tweet right above the hd-6 in door

Amp-3 - JL 500/1
Subs - ED 11KV2's in 30 HRZ ported enclosrue

Review:

The m6's are nothing short of awesome! real big difference in the m6 as compared the HD-6. Midbass, never knew what it was until now!!!!!! And I have no even tuned the h701 yet! No TCR nothing yet. The tweets are awesome very warm and smooth, replaced the JL XR's with the DRT 25,26 upstage combo. The US-200 x-over is soooo adjustable.

Thanks Don Isaland Sound labs for all your help and product choice. I got the entire m6/us-200/DRT 25-26 set for $365 brand new in box.
