Will an 18inch soloX kicker fit in a 2002-4 bmw 745i

Question

im thinking about buying a bmw and just to spice it up since im young would a 18 inch kicker fit in the trunk im not shure how big the trunk is and i only want one not 2 hat would be too much...but anyways thanx

Answer 1

yes it would fit but the bigger question is do you want it to fit, you are better off going with a set of 12s because when it comes to the amount of bass you get RMS wattage is important but not as important as cone surface area (and two 12s have more than one 18), the 18 will require a custom box and you can find a lot of prefab boxes made for your particular subs' specs

Answer 2

18 inch speaker are a waste of money..They don't sound any better than 12 inch,and also use to much air space in the box.

Answer 3

The recommended air space for that sub is 10 to 12 cubic feet vented.  That is a huge box.  Probably not a good choice for that vehicle.
