You have four 12" subs and your looking for SQ over SPL? Seems like overkill on the low end for SQ.

Yeah, I have two downfiring under my backseat, and I went to my local shop yesterday and the had the ia 187 12"s buy one get one half off so I bought two more lol.

you bought two more because they were on sale, or because you felt like you needed more low end in your system?

well the port needs to breath, so is forward your only option on that part?

Both kinda, but i had already planed on using four of them and two elemental designs nine.1 amps, so I got them and I am the kind of person to overkill things, I am in the process right now of putting a r6 street bike motor on my yfz450 fourwheeler lol

definately DONT do side firing if its real close to the wall. It messed up my sonaces :/ but i have alphas now bc of it //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif so were good. I vote take the back seat out and do a 8cu ft box tuned @ 30hz subs up port up //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

He hasn't said anything about a ported enclosure, or about it firing forward.

His enclosure right now is downfiring, since you haven't given much info I'll assume that right now your still planning to use the rear seats and that the downfiring box is sealed and under the seat.

Well no crap? That's why my down firing design the port is 7" off the floor and it can face forward and up also?

I'm more SPL than SQ, but I would think that with a real SQ system you wouldn't want too much on the low end. You want just enough of the low end to keep everything sounding really nice and not overpowering the mids and highs.

Oh my bad and the box is ported under the seat and I plan on taking the back seat out and using a ported box for the four of them.

if your using 4 of em, SQ is not your goal...

suns up and port up

In that case you'd want to go ported. Tune it low, around 30-32 Hz and port facing the roof.

subs up and port up

that was pretty much my point from the beginning. The SQ systems I've seen have one sub, maybe two at the most.

guy around here has 3 15's in his trunk for his SQ setup. Sounds amazing...but he knows what hes doing and has a lot of money in his ride.
