dual 10' s or quad 8's

[john253a]

Has anyone bothered to check the m/depth and does the ssd10 even fit the way he wants

If you want loud and can power them correctly the sa8v2 x4off ported at 32-33hz will do the job

If you don't plane to through 3k at them and drop $750 on subs alone the look for something else

Like 2x 10

If you using.a prefab don't go ported, stick to sealed

If your going sealed

4 off on 2k at1ohm

And they get loud for a sealed sub

SSD 10's are a tad under 6.5 inches from base of motor to the bottom of the gasket. I know because I have one. If you build your box with 1/2 inch wood then you can get away with a 4 inch top depth and 8 inch bottom depth as the outer dimensions of your box. Once again, I know this because that is how my box is set up. Price/performance, the SSD's are his best bet, then later down the road he can upgrade to a pair of BL's because BL's are also a tad under 6.5 inches top depth.

so the two ssd's or bl's would be louder than four sa8's?

It all depends on the box. SSD's or BL's would be a lot more simple and I think you would like them more. 4 SA-8's is cool to have but I think you would expect more out of them than what they would do. 2 BL's on 3.5-4k or 2 SSD's on 2-2.5k is my recommendation. My SSD is on about 900w when my voltage is good, tuned at 34hz, and it slams everywhere from 28hz-60hz. The 8's would probably have a bit more trouble digging down below their tuning, but it all depends on your box and power.

I got my sa8 at 33hz on 200rms each

And I play down to mid 20's no problem, high passed at -6db 24hz and a second at -24 at 20(built in to amp)

The serious fact of the matter is, you're not going to get TERRIBLY loud with an under the seat box in your truck. Built right, either setup you choose will sound good AND get decently loud. You'll spend a lot less on subs by going with 2 10s rather than 4 8s of the type you're looking into.

If you can fit 2 10s on the face(baffle) of the box, do that with a port in the center of the subs firing forward. Fi SSD would be a good choice, and so would a Fi Q as a VERY musical sub with tons of Xmax(Id run this option of you have room for a bunch of port, which might not be the case).

BTW, we can't tell you what we be l

louder in your truck, we don't know. You'd need someone that has EXTENSIVELY tried both serious in the same truck. We can guess and make assumptions, but there isn't a YES or NO. We can give you opinions on how we would do it, but at the the end of the day, it's your vehicle, build what makes you happy

I'm seriously thinking about have two enclosures one with multiple 15's or 12's and one for under the seat
