Try going to the Ma audio website. We would need exact model's of your subs to try to draw up a box. you could do four square ports at the center of the box for each chamber I wouldnt reccomend it but it would look good if pulled off right

How many bodies can you fit in the trunk? If less then three you probably don't have the room, especially for ported boxes for 15s.

well if your planning on a wall i hope you have alot of time patience and big pockets. I will see what I can come up with for each box on them, what kind of amps will you be running them with? where are you from also?

well from what I am reading the optimum for each sub would be 3.25 cu ft per sub, the vent would be 37 sq. in by 12.5 long.. as far as power goes you would be underpowering a little bit but you could wire 2 subs in parrallel to get an 8 ohm load then wire those sets of 2 in series to get a 4 ohm load, then bridge on the amp for full power. But i cant remember if you can bridge the 81000d. it might just have one output

are those subs dvc or single, if they are single then I agree with Jeff, If the are dual then I would series each sub woofer and then parallel the sum of them together. The MTX amp has two sets of termianals but is a mono block and bridged internally. So you can just hook up two subs to each set of terminals. BTW, walls arent all that expensive, just generally ugly, thats what I use right now in my S-10. Kinda fun to play with but SQ is absolute sh*t.

fair enough, if thats the case then that amp is a bad match for those subs. I would either get a second one or sell it off and get something that is either 1 ohm stable or get a couple of mono block amps that are 2 ohm stable.
