Mini Marty Sub Question

I built a mini Marty about 3 months ago, killer sub, I love everything about it. I have a iNuke6000dsp to power it, how many more of the mini Martys will thus amp push?
Also I built the sub and asked if I should use any polyfill,I was told no, so I didnt. Would asking some in make a difference?
Thank you all in advance!

The 6000 can run 2 easy, four would be pushing it. Don't think three can work since you can't bridge.

Not sure about the amp question, but if your build was one of the larger Marty variants, I would suggest you add either some poly fill, foam or pillows.

It depends on the drivers that you have. What do you have?

Should be able to Power 4 SI's,.. 2 SI D4 on each channel wired in parallel for a total of 4 ohm load . (3100W x 2 channel@ 4ohm), each sub will recieve 1500 (1100W) each.

If your Marty is similar to mine (which 24x30x36 WHD), then three regular-sized walmart pillows will be sufficient. Here is a picture of how I placed them in the sub. And not to worry, their position does not affect performance in any way.

If the above is your driver, its impedence is 4 ohms.

Assuming the manufacturer specs are accurate:

A single driver on each channel (so two total) would get 3100 W @ 4 ohms. You'd need to limit the output of the amp to protect the drivers.

You could hook up two drivers in series (4 ohms * 2 = 8 ohms) for 1600 W @ 8 ohms / 2 drivers = 800 W / driver. This is per channel, so using both channels, you could hook up four drivers.

You could hook up in parallel two sets of two drivers in series (4 ohms * 2 / 2 = 4 ohms) for an impedence of 4 ohms, you could hook up 4 drivers per channel for 3100 W / 4 = 775 W / driver. Using both channels, this could be eight drivers total.

You can mix and match how many you have hooked up to each channel since they're independent.

Thank you! That was really helpful, I think I'll start with 4 total, then maybe go to 8. Just never enough bass is there??

The 3000 was bench tested to put out 2000 watts bridged into 4 ohms. The 6000 is two permanantly bridged 3000s. So 4 SI would see 1000 each. That certainly should be enough to push them hard but I think you can run up to 1300 watts each. So 4 on the 6000 leaves a little on the table.

Here is a chart showing the actual rms numbers

http://music-group.force.com/PKB/art...fs=Search&pn=1

You would be fine running one more dayton with plenty of headroom but, 4 of those drivers on that amp would get 550 watts each. I would get a different amp or different drivers before doing that personally.

Either two UXL-18's or four SI 18 D4's

Atabea, do you have a build of your sub anywhere? Im looking at making my mini a bit smaller than spec and front ported like you and trying to research everything.

In my previous post I wrote the SI could handle 1300 but I think it is 1100 not 1300.
