mid bass speaker in door
I recently did the b14 seat belt conversion in my b13 coupe which freed up a ton of space. I was wondering if anyone has ever cut a hole in the panel where the seat belt assembly used to sit, and mounted a midrange/ other type of speaker. I was thinking of mounting a 8 inch midrange speaker connected to an amp that I have. any thoughts?

I think it could be done well. Although I don't like to half-ass things so I would use Dynomat, sound deadening material, and a carefully chosen sub for the door size, a mid, and tweet ...I believe the mid is necessary for the frequencies in between the sub & tweet.

I used a Boston mid/tweet setup w/a crossover in the doors and some 6" mid bass + tweets on the rear deck and a single JL 10" sub in the trunk...amps are a 4 channel Alpine and a Phoenix Gold MS250, also have an Epicenter by Audio Control...I think it sounds excellent and I'm pretty picky.

It would work good,and theres a ton of airspace with the seatbelts removed.If I was gonna do a higher end system,I would do it for sure.

I have mounted 8" midbass drivers in the rear side panels before. I have done them with and with out a enclosure.

How did they sound

the speakers sounded good but the sound stage was wrong due to the placement of the speaker.This was in a show car so eventually I convinced the customer to have custom door pods made so I could fit a good sized mid bass driver in the door. Even though it was a 6.5" speaker the sound stage was better due to speaker placement.

I would rather put it in the rear quarter next to the seats. For a true mid-base driver you want it to be omni directional much like the subwoofer so you do not know where the sound is coming from. You will need a nice bandpass cross over from 80hz-150hz range, too high and it becomes directional. You also want it in a precise enclosure, which is difficult to do in the door. A good 6.5" will accomplish this, no need to go to 8". Make sure you put some power behind it as well to control the coil. Too little power is almost worse as it can not control the movement of the speaker and you end up with more distortion.

One thing i am going to test is a 6.5" under the front seats pointing up. Then a 5" and tweet in the door.
