new to the forum here and looking for some help. Im looking to get the Q 12". I have a reg cab truck so really limited on space. The max dimensions i want to go are 48L x 14H x 7BD x 4 TD so my max volume is 1.345ft3 MAX. This means i will need to invert mount it between my seats. (ive done this with an alpine type r 10") want to get a 12" tho now. I am running an alpine MRX-M100 with 4awg power and ground. 130amp alt and stock battery. Should i make the sealed enclose slanted as stated with the dimensions above? or make a rectangle box 14x48x5 (1.117ft3 before displacement of inverted sub) and have room to mount my amp on the front of the box between the seats? (done this before with no overheating issues) Also what upgrades should i add/ what are some of them for? i.e the high QTS? any help or comments are appreciated
