Convertible sub woofer install options

[ProTouring442]

There are som seriously shallow 8" and 10" subs out there you can work into the doors. This is probably the route I will take with my '72 442.

would you be putting in a mid in the door as well? or are you expecting the door sub to play high enough up to blend with a tweeter?
also, the performance may not be optimal since you really can't seal a door. I'd shy away from this approach. maybe an 8" mid in the door but leave the sub in the trunk .

Although I've never did a stereo install in a convertible, I have set up a few in commercial panel vans that would ride a lot with the doors slid open on the highway.

You need a setup to put the actual sub air pressure up front. This could be ported from trunk as mentioned, firing into backseat, mounted in rear deck ,or small compact design subs in small custom boxes under seat. Bazooka tubes could be an easy option if you could fit under or behind front seats .Downfiring could be good for under seat, sound is more naturally dispursed.

As far as sound quality, subs made for tiny traditional boxes tend to have more of a peaky one note sound & are less efficient where larger sealed boxes produce more natural clean tones.
Google interiors by Shannon, I think some of his cars had perforated aluminum grilles worked into the rear interior for ports.

Also necessary for any great convertible stereo is very sufficient clean amp power for all speakers & a good eq setup. Don't want others to hear your cheap distortion.

Just my thoughts.
