Few Wall Qs 4x Massive Audio Dmx15s


Recommended Posts

Hey,

Just a few quick Qs if someone can help out.

I'm putting in a wall, 4x15"s.. My car has a sunroof. What would be the best way around this without welding a metal plate to the roof? Would the sunroof make a huge difference in my db readings? will it begin to leak? would I be better putting in a MDF roof? if so how would I secure this?

And.... whats peoples opinions on the DMX15 from Massive Audio? each pair is being run off the P3000.1 amp..

Never done a wall, so any hints and tips from the Pros would be gratefully received! :D

Is this going to be a competition only car, or do you need to drive it everyday?

I'm pretty sure theat when the sunroof glass lifts, it's gonna cost you in SPL, but if its a daily driver, why not keep the roof and enjoy it once in a while. ;)

A kid round here had 2 of those amps on one of those subs, I didnt really care for it... The amps they look kool n all but they dont do there rated power and are slightly overrated..

Would be a daily driver, but would like to compete in our regional SPL comps.

I say keep the sunroof then. If it gets to a point where you are gonna break it, then look to replace it.

It's just like another door or hatch on the car, it's gonna flex in it's rubber seal.

I don't see 6k watts tearing the metal roof or breaking the glass, so I would keep it.

oh ok thanks for that..

Kinda disappointed to be honest.. Is Massive Audio gear not that loud?

In relation to sound deadening - I'm building a wall, is there any need to sound deaden behind the wall? or should I just concentrate from the wall forward as in theory the wall should be sealed from the back of the car correct??

We did an install in my dads truck with 4 of the 12" DMXs and two clarion dpx11500s...Its loud. No wall, pulls 46s and 47s on TL...heres a vid

. So if you do it right they will get loud, good subs man. But not a big fan of the amps.
