box problem for a 85 cutlass...too close?

[900blk 0]

ok well i have a 18 q im going to put in my trunk .theres plenty of room . my box will be about 8 cubes tuned to 28. the problem is i can only mount the sub on top because the trunk height is only 19 inches...is itgoing to sound right with the speaker up close to the trunk lid...besides major outside rattling would there be any other problems?.thanks

really close like an inch or two

you'll probably want at least a couple inches of clearance. Not only to allow for the excursion of the sub but also to give it some room to breathe and allow the sound to travel out laterally.

I also have a 87' cutty myself and actually u dont even have 19" of trunk height. G-Body trunks are built very short but wide. And yes, with a sub bigger than a 12" in a G-Body ur going to have to do subs up/port back or port up. Really Id sell that 18 and get 2-12s. Then u could go subs and port back. Really u shouldnt go any higher than 14" of enclosure height in that car and thats if ur doing 12s and subs back like I said. If u do use your 18 then Id suggest u do subs up/port back and make your enclosure height about 12.5" and as wide as u can get it....which is about 58-60" before u run into the trunk supports on the side. Trust me I have that same vehicle and I know it inside and out.

that will give u about 2.5" between the sub and trunk lid which is still too close in my opinion but u have to have a lil gave inside the enclosure between the motor and back wall for the sub to breathe. really like I said Id sell and do 12s. Really for that car even 15s are too big due to the height. Dont get me wrong Ive seen people get them in there but I know their parameters were nowhere near right. they were either sealed or tuned like a flute (some bs).

u can still use it but sub up is the only way ur going to get it in there, even if u angle the baffle...its still going to be too much of an angle on the enclosure and then u'll be running into problems with the build because the magnet on the sub will be hitting the floor of the enclosure and probably wont fit. Subs up/port back is the chit in a suv or hatchback but its a maybe in a trunk?

my friend had a car like that, I forget the year but it was close. Anyways he had 4 12's straight across the back in a sealed box and......yeah it got loud enough. They were only Orion XTR's too.

i have a 89 caprice do you guys think i will be able to get four ported 15's in the trunk???

not properly

so what will be a better choice 4 ported 12's or three ported 15's

Id say 2-15s all day. U have plenty room and I use to own a 79 Buick as well so Im pretty familiar with Box Chevys. And to the guy who said his friend had 4-12s in a sealed enclosure that got loud enough....I bet if that guy had 2-high end 12s in the proper ported box.....it would have sounded just that much better too. Im also a East Coast Ryder and its like I tell alot of guys who ask "Can I fit this particular rim on this particular car?" with a bullsh*t lift. Yea, but just because it fits or works doesnt mean its right. If u go ahead and do it correctly from the start then it will save time and money in the end.
