Two 18's/mini Wall/ Cavalier

[jonathancullen89]

alright im going to be getting two 18" mach 5 audio subwoofers and a clif designs amp. now i have to decide on a box.

i did not like my last wall, i like to be able to see out of the back window so i want to do a mini wall. im not sure what i should do about subwoofer placement though. should i do subs up ports up? or should i angle the subwoofers toward the rear more so they are more firing toward the back window. to get the airspace i need for two 18's i am going to rip out the back seat (exposing the trunk) and building the box into the trunk as well then mounting the amplifier in the trunk.

the subwoofers will together be seeing 1200wrms, that is if the clif puts out that much, so what should i tune the box to?

i was thinkin maybe 32-35 hz because i do want it to get reletivly loud and how much port area so i need for the two subs? is there a port to big? i was thinkin maybe a huge ass port would be best but i am lost.

i am open to suggestions on anything, thank you.

this is what we did with my cousins cavy , it sounded the best out of all the ways we tried it.

wall off trunk = red lines

box = green

that actually looks like it'll work good^^

i need at least 8 cu ft though, and also a huge ass port. i like that how it doesnt go above the rear window though.

do you guys think i will have to build the box into the trunk to get 8 cu^ft?

how big of a box did you put in there and what size subs?

thanks
