Next install is a Lotus Elise. The stock setup is 5 1/4" in the rear wall and 4" point source in the dash. The cars are known for terrible audio and having zero space for a sub (I've been looking and have never seen one with a ported box or with more than .6 cu. ft sealed).
My goal is midbass with serious impact. Here's what I'm planning:
Rear wall will be HAT L6SE on 150W/side
Dash will be Morel Virtus 402 on 75W/side (probably will keep passive xover)
Sub will be JL 10TW3 on 600W in ported enclosure (.6 cu. ft.)
So I have a couple questions. First, the 6.5 in the rear wall are in very small sealed enclosures (body is fiberglass and speaker pods are molded in). This could be very good, since I can rework the enclosures however I want. Since I don't have to deal with leaky doors and can run these as dedicated midbass drivers, what is my best option? WinIDS shows significantly better response (3-4 dB) if I port and tune to 50-ish Hz. Any reason not to?
Second, any tips for tuning? Where should I start in crossover between sub and L6? How low can I safely play the Morels to keep as much of the stage in front of me as possible?
Thanks for the excellent advice I always get.
