3- 8W7's in a ported Box can it get loud?

[davidtemple 10+ year member]

I'm designing a box for 3 8w7's in a ported box. Doing a SQ install but just wanted to be loud enough for MECA if needed.

[1] Can I use one port for all 3 subs ?

[2] What SPL can I expect in a SUV firing back at the hatch? ( SQ ) Install

[3] I want to use a JL HD750 on all three subs with the gains lowered, will this be ok?

Any Advice good or bad would be appreciated. //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

An HD750 on each of the 3 subs, or just one for all 3?

One Amp for all of them? Not good?

I thought you meant 1 HD750 for all 3 subs?? Or do you mean an HD750 for EACH sub??

Correct one HD750 running all 3 subs...

Not nearly enough power.

How much Power per sub would you use?

I think 300 RMS is max for these.

What amp would you if you use JL or any other brand?

Sundown SAZ-1500 would be good for all three...depending on the ohm load...or if you want to stick with JL, throw a 500/1 on EACH sub.

It would be a lot cheaper to use the Sundown Amp, Never use one are they good for SQ also? Reliable?

Incase you're thinking an 8" woofer will have better SQ than a larger woofer, you're mistaken.

Two 12W6v2's will sound better & get louder (given the same power) than the 3 8W7's. The 12W6v2's will also do fine on the HD750, but would be better off w/ a PDX 1000.1.

Two 12W6v2's in a 2.75 ft^3 sealed enclosure =//content.invisioncic.com/y282845/emoticons/drool.gif.b5e863e893038027711d4402f340dad0.gif

Eh, sounds good except for the PDX amp..those don't have any balls to them at all.

Go with a Sundown SAE-1200D if you decide to run two W6's...

Just don't know about these Sundown stuff.... need to ask around, I'm looking to get 140db with these 3 vented, if not I'll go with 10's or maybe 2-12's, I got a PM saying to go with FI Q's.

Any opinions?
