Maybe try asking here?....hamm...no mark? I will PM hem in a lil bit
will I tried to post a link to a box that I made but it did int work but hear R theJeremiah, what are you trying to achieve? Why don't you post the maximum dimensions of what you can tolerate in your vehicle and which driver you plan to go with. Folks here can then come up with a properly tuned box and shoot you the plans to build it. No more problems.
BTW, the MAW-15 has a displacement of 0.4cu. ft.; the MJ-18 displaces 0.47cu. ft.
Best,
Mark
