    Mtx 8000

    Well i rescently purchased a MTX Thunder 8000, well actually lastnight i purchased one And i am set on building a sealed box because i have a extended cab truck and their isn't a whole lot of room. And i don't like the idea of alot of wood working. The manufacturers data report for the boxes tells me five diffrent sizes for sealed boxes. I'm wondering if i should use a recommended box or if a custom box would sound better and pump harded, Can anyone suggest something?

He is wanting good SQ and good SPL say a 50/50 or 60/40 split....about the biggest box we can squeeze out is 2.25-2.5(if we are lucky) ft^3.

    For a single 12", maybe 1-2 cubes sealed.

    You could go 2-3 cubes ported at around 28hz if you wish.

    If it's just temporary, maybe go 1.5 cubes sealed, or 2.5 cubes ported at 25-28hz.

    The sub is a long term temp sub hahah ,But the amp is short term temp. He will probably upgrade to around 500wrms...

    Re: Mtx 8000

    There's endless reasons as to why it doesn't sound like it should ...

    Box has a leak somewhere.
    Sub isnt sealed against the box properly.
    Sub is wired wrong to the amp.
    Box is too small.

    You gotta remember, it's a single 10" with little power ... if you're used to a different system with more drivers and more power of course it's going to sound weak and inferior.

    Re: Mtx 8000

    well maybe it's not sealed perfectly. it's wired to run at 2ohms, well according to the wiring diagram. It's runnin bridged. The amp was runnin two jensons before and it was louder then this so the box must not be sealed perfectly

    Well it's not the box being unsealed that's the problem cause it's sealed. maybe i need a bigger box.

    Re: Mtx 8000

    ummm...go like 2 cubes (after all displacement) ported at like 30hz. Send it 400-500 watts rms and it'll be pumpin...i've dealt with mtx 6000s and 8000s before...decent subs. Give them room and power and they'll do well. peace
