my opinion is that a trunk with seats folded down sounds the best cause no rattling(im talking firing inside)but there is no comparison in a spl evel a hatch wins easily
ya hatches are louder generally unless you do some major customization of a vehicle w/ a trunk( cutting a port through the rear deck) but vehicles w/ trunks may sound better b/c you don't hear the reverb of the subs b/c they're right behind you. its pretty much the same thing as a truck and SUV.
my buddy has a 1230 with about 240wrms going to it, and I have a R with about 500wrms going to it, and his is at least twice as loud. BTW, he has a small precida hatchback and I have a corolla
yeah. hatches are basically just like SUVS. and SUVs in my opinion sound the best. trucks sound good as well. but SUV's are awesome. the only thing is with a hatchback it's easier to get your stuff stolen obviously. in a car. if your seats don't fold down, they have to put the trunk. they can just break a window in a SUV or hatchback to get in there.
Yea or you can just make a sub wall in the car facing towards the front of the car and no matter what you have itll be crazy loud. If you want it to really be as loud as possible
