by the way the whole box thing, you can have it all in one box as long as there is a center divider to keep them separate, looks like u've done everything good, juss make sure the boss amp has lotsa cold air near it cuz they do have a tendancy to heat up a fair bit.

Yeah on hot days, I bring the split fold seats down to keep the amps cool with the air con, cause I mounted the amps on the back of the seats for that reason. :)

correct me if i'm wrong, but i read somewhere that liquid nails isn't good for box making as it dries hard like nails and can shatter under extreme pressure (sub thumping in a sealed box).

If you are really worried, there are more flexible options then liquid nails. rubber cememt for example. Of if the glue is not structual (you're using nails/screws to hold the box together), regular silicone will seal it up good.

it says 2-ohm stable. So as long as the two subs are identicle and the boxes are the same internal dimension, you should be able to run them briged at the amp and in parrallel. ie, take +'ve and -'ve line from amp to first sub, then from that sub run another line to the other sub. By doing this your amp will work hard so ensure good ventilation, and decent size power cable as well. if its the only amp in the system 8Ga will do. Subs really work better when under a LPF, clarity and punchyness is noticable


Ok, so the amp is 2 ohm stable, so does that mean that the subs haft to be 2 ohm's as well? cause I know for sure that the subs are 4 ohm's

usually a spray can foam, personally i've never used it, but i'm guessing joolz is telling you to use it as just another form of sealant kinda
