Long time since I been here, but I need some advice on a new install Im going to be working on. Right now Im thinking about doing everything in spring when this **** snow melts so I got some time.
My new install is going to consist of two 12 inch dual 4 ohm DD 9512's, with a DD Z1 amp. Thats the only thing I know so far on whats going into the car. The car is a 1990 Ford Thunderbird Supercoupe 35 annerversory 3.8L V6 Super charged.
What I am wanting to do since I have fold down seats is have the box firing foward into the passenger area/cabin of the car. The trunk will be completly closed off from the cabin of the car. The box dimensions I have to work with is 38" w X 15" h X 40" d. The box will be made out of 1" thick MDF and braced internally. Comes out to about 9.5 cubic feet internal, not including port space, or bracing.
I drew a quick little pic in microsoft paint, but neither did I have the time or will to do a good job, plus Im lacking on them paint skills..
A couple questions I have after looking at this pic are:
~Should I give each sub its own encloser having a extra board dividing them down the middle with a vent for each sub, or should I run one big vent and have the subs share the box space?
~Which ever way I go what size should I make the vents?
~I wanted to notch out the back of the box so I had a place for mounting the amps and everything, will this notch in the box mess with the sound performance of the subs?
My illistrations are to help you understand what I mean by notching etc so please look at it, and also read the captions I wrote in so you kinda know what your looking at... LMAO.
