Help - Box Build RE MT 15s


Recommended Posts

OK, I have 2 15 MTs. All the specs I have are:

Sub:

Dual Progressive Spiders

Flat Wound Coils

Dual 1.4 ohm

Dual Tinsel Leads

Electrical (plan):

350 Amp SP AD244 (adjustable VR)

Big wire throughout (1/0 or greater)

Kenetic 16v/12V batts (3 or 4 will add more if needed)

Amp:

SS XXX4000d ( @ 16+V )

Will double after initial install and testing.

I've tried emailing RE with no response...

PORTED:

I would like to know what kind of airspace these need. Looking to port Looowww like high 20's low 30's. Thinking 6" x 30" for port surface area then port length to the box for the target frequency.

Thanks in advance for any help...

/cheers

Congrats on the great sub! They are awesome aren't they?

Post a pic with your username written on a bit of paper in the pic so I know you actually have one and aren't just dreamin' on here.

I have 2 MT 18"s, and we just used the T&S parameters of the old BTL (non neo-mag one).

If you actually have that amp, get rid of it, if you don't have it then good, don't get it. New Soundstream is shit in general, but those amps are even worse.

Not to be an asshole but I'll help more if you prove you actually have one :)

Will Post an image tomorrow. I'll need to unbox them. I understand the request with my "2 Post" count :pardon:

As for the Amp. I have heard mixed opinions about it. It's what I have so I'm going to run with it for now.

Ok cool, they are beasts! Haha.

They aren't very photogenic though eh, they see to look smaller in pics.

Yeah, after having so many people come on here with a brand new account and ask for advice on their big build when they don't actually have any of the equipment you have to double check eh.

Ok, if you already have it then I guess it's fine, but consider swapping out for different ones.

So what kinda box were you thinking of, what car?

Car = S10 ext cab (1998)

Box:

I'm thinking either large ported or bandpass if possible. One problem with bandpass (4th order) in this truck is the bed dimensions...only allows for 16" total box height so the subs would have to be angled...not sure if I wanna do that.

If I go ported (leaning towards this) I plan on using the ext cab area to mount the subz...cut-through inside the box and additional box volume in the bed (yeah the cut-through will need special attention to be air tight). I wanna let the beasts breath! ported in the cab from the top of the box followed by 2 45degree angles into the bed. Something like this...

Hmm, yes, this idea could work and look very nice if thought through well. It could be tricky to get the extra volume in the bed to not be too restricted at the cut through point.

And might I say those 15"s look so beefy compared to the pics of my 18"s, I like the foam pads to stop tinsel slap too :)

This. I'd not recommend doing a box like that...just too risky depending on how small the cut-through is going to be compared to the normal size of the box.

Yeah I agree with both of you it is risky. The cut through is going to have to be huge to compensate for the short height of the bed. I would be using every inch I can squeeze out of it leaving enough room to glass and attach to the body...

Unless I can spec out a good 4th order BP in {16" X 39" X 60"} which will be tight with the 15.5 dia of the sub. I may be able to shave a bit off by removing the gasket though...and notch out a section in the top and bottom of the box.
