Wanting to get some advice from the pros and oldschool junkies in the hobby. I'm doing a wall in a 92 Bronco with 8 12's and I have been getting mixed opinions on whats best for audible loudness purposes. I was told a bandpass would be my only option for a wall because of what I'm wanting. And a bandpass has self internal loading walls therefore putting the pressure and audible loudness by the time the wave comes out at my ears in the seats.
If I was to do a regular wall with all subs and port firing forward in any position, will cause the subs and port to load off the front windshield, dash, and firewall and putting all the sound and pressure out the windows and scattered everywhere else but at my ears.
The subs I'm going to be using plot well in a 4th order with .8cu per sub @44hz tuning and 1.4cu sealed per. The response is as flat as anything musical should be from 26-70hz before any +/-3db. Also without taking into any account for cabin gain.
