Weekend Fun - MJ-18M + SD-12k

[mrogowski 5,000+ posts]

Say 10-15 cu ft @ 32hz with a couple 6" aero's. I know its hard but I was asking more so if its possible for the MJ's to take it. I ran 1200w RMS to one and it was great but that wasnt an MJ-m.

This guy under test was tweaked fairly heavily and probably wouldn't do too well at that low of a tuning. But let me get the BassRacing done on it and we'll take things from there.

I'll post the results here if you wish.

so those power ratings are at 16V+ //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gifvery nice indeed...

curious to see what they would be at 14v in a standard street set up

minus the battery bank //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

good stuff

Yeah I suppose. I assume you are referring to the raw output of the amp at that voltage?

I was truely suprised by this driver. It was quite the evening test session.....Oh and Murilo is crazy! //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

That looked like fun what kind of box would the new mj's work in.

Ok, so we did some BassRacing with the unit today. It held up to 4kw over the 30 second duration, but was stressed. We concluded that 3kw is a good number to apply to them.

The rest would of course be up to the install. The output we saw in our setup would make this a good 139.9 driver.

is there any modifcations to the motor of the mj?

same size?

Hello George

Actually those bats are pretty dead.

When the amp outputs 16kW the batteries drop to 14.5V, with 2 amps 30kW and 13V.

I can say that now that is the main reason why the van is not doing 59.9 with one amp, but after rounding the box and new door panels I think will be done.

Looks like you modified the top plate quite a bit as well...looks pretty interesting to say the least.

 

[mrogowski 5,000+ posts]

Yeah, much has been "adjusted" on this unit. I'll be doing up a few more tweaks - who knows, maybe after that it could take 4kw easily...

Holy ****, floating... charger?
