That is simply beautiful, and there is still room for occupants. Do you run a subwoofer as well or are the two door woofers enough? What frequency do you cross the two woofers and the MTM unit over?

Impressive

I have a love-hate relationship with kickpods...I love the way they sound, but if I'm driving any significant distance, my foot just naturally wants to go to that dead pedal space. Maybe someday when I can dedicate a vehicle just to audio projects.

Nice work. I'm sure it sounds great!

So would the midrange be equivalent to the 4" Morel, or are they smaller?

Neat project, I'd be wanting to try an IB sub for sure. Anyway just thought I'd suggest some guys are talking about coax, but not auto made coax. They are running the ones from seas, hi-vi, and the like.

A BP box could work, but without large midrange/midbass they have such a narrow band.

You can run something like an icepower alpine pdx 4ch its all class d takes less power.

Otherwise my old rule is go larger drivers for more sound. When I was installing in boats (offshore vees) I'd always try for two pair of 6x9 to start with and 7x10 were better yet....could get away without subs with four of those. Open air sound is different than closed car, no doubt about it. (lot of them didn't want subs due to extra weight and lack of room.) It sounded a lot like a very good dj/sound system in a smaller bar.

Currently i dont run a sub, but i plan too look into it as soon as some substensial work to the car itself are finished (suspension and brake repairs)
The problem with this car (85 929 (Cosmo) Coupe are that the gas tank steals as much luggage space in the trunk as a large sub box would do, so a quarter panel installation migth be a solution.

X over betwin tweets and mids are 3200hz/18db oct and betwin mids and woofers are 200hz/18db oct

I use a Alpine CVA-1000 with a PRA-H400, so i have on screen adjustment for x over frequenzies and time correction

The speakers are powered with a RF 400x4 wich feeds the tweets 50Wrms each
and the mids 50Wrms each (100W a pair due too 2ohm load)

The woofers are powered with a RF 200x2 @ 100Wrms each (200Wrms a pair due too 2 ohm load)

They are identical too Morel car 4"`s (i belive their outside dia are 102mm) but have a sligthly smaller flange than Morel home versions



Inner baffle with cutout for mids



Mids are sandwiched betwin inner and outer baffle (grills are sligthly smaller than the mids themselves)

You have some pretty serious money tied up in those kick panels!

4" midrange with 2" voice coils? I assume they easily deal with 50W each.

901Fixer:
With 6" Morel woofers, you could bypass the mids and use a stout tweeter that can reach 2kHz or so. Those woofers are good down to about 50Hz and handle (also require) hefty amounts of power.

Or the 4" Morels in MTM with a larger woofer or two would be reasonable.
