Feedback on build requested - SQ goal

I just got back a quote for my 2018 Honda Accord 2.0t Sport. I'm sensitive to highs and really like a warm sound signature, so went with Morels.

Full front door sound deadening treatment. Rear speaker deck treatment. Trunk treatment. License plate. Rear wheel well treatment (cabin side). Treatment under spare tire / trunk bed.

Stock Head Unit with DSP/PS disabled and ANC disabled **Hertz S8 DSP** (my local shop doesn't carry or support Helix, or I'd have gone the mini route) **JL RD900/5** 5-channel amp 75x4 + 500x1 (at 2 Ohm) **Morel Hybrid mk2 62 front components (2 way)** **Morel Tempo Ultra 602 Integra rear (Coax just for fill and rear passenger)** **Skar "stealth" 1.06 cubic feet sealed enclosure for Honda Accord** **Image Dynamics IDQ12 V.4 D4 subwoofer**

They will time align and neutral response EQ using a dedicated HQ microphone.

Anything you feel is missing in this equation? Any problems jump out at you? Anyone use the Hertz S8 DSP? Like it? Don't?

Thank in advance!
