Ok in 2007 i bought 2 fully loaded 18bls. and had them in my 95 deville. but now i have a 03 and the trunk is a little smaller. right i just have one in with a 6. 75 ft3 box tuned to 32hz. well my other one is just sitting in my room wanting to be build. Ive blown both of them but reconed one couple months ago. but i want to put both in my 03 .the max size in my trunk is 41x40x15. if i keep it at 32 hz the ft3 will be 7.55, i know many will say that would be way small for 2 18s but i already got might as well just make a new box and put it in. My question is would both of my 18s at 7.55 ft3 be louder then just one at 6.75 ft3?

Thats over 1 cuic ft. smaller than the minimum recommended. It would definitely not be ideal for the subs to be placed in a box that size and could end up sounding terrible just so you can get a little increase in output. I would say either sell them and step down to 15's or just stay with a single 18.

how the hell did you blow both of them?

one in an optimum enclosure will be better than two in a tiny enclosure

BTL? or like he said step down to 2 15s BLs
