6 Dual 4 ohm subs, suitable amp?

[Gearstix 10+ year member]

I'm trying to find out how much it will cost me to get an amp thats either 2.67 or .67 stable (thats what they say it will be with 6 dual 4 ohm subs on another fourm) Or a amp that will work with what I got.

I'm thinking about running 6 8" AudioQue SD2 subs, with an amp thats 3000-3500W in a ported box due to space restrictions.

You could get a Mmats d3000.05. Its half ohm stable and will due a true 3k as long as your electical system is in line. Its kinda pricey but Mmats is quality stuff.

get my Solid Audio F2500D to run those at .67ohms //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

12 4ohm coils paralleled = 0.33ohms

series then paralleled = 1.33ohms

Its six subwoofers that are dual 4 ohm subs,

would that not make it .67?//content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif

dual four means there is 12 coils in all

I had a budget around 1500 for my amps, subs, alt, deck, etc, but I won't have it right away. I'm a student in highschool so I'm just working this summer.

The Mmats D3000.5 is $999.99 on WoofersETC.

I dunno what I should do because, I have a regular cab sonoma, I want good subs but I want space in the cab aswell (6' 1").

I found with my other setup in my car, it would kinda struggle on lows. I'm trying to do a loud stereo for my truck that will hit low.

Oh, yeah your right.

So I don't need a .5ohm stable amp or whatnot, could run a 2 or 1 ohm stable one?

x2, Problem solved here. Wire each dual 4ohm speaker in series, so you end up with (6) 8ohm drivers.

Then wire them together in parallel for a final load of 1.33 which pretty much any amp thats 1ohm stable can handle.

I know alot of people hate on Rockford but I have always been a fan. All of there BD amps are 1 ohm stable. With your budget I dont think your going to find a true 3k watt amp. You can get a P1000-1bd for under $400. Here is one pretty cheap:

I'm kinda thinkin it might be better to get either one 12 'large sub' in a ported box, or two or shallow mount subs.

maybe something like a Mmats Dreadnaut or P3 in a ported box, or a couple Kicker CVTs.

I've got a space thats 52" long, 23" tall, 8 1/4" wide.

I should be able to get around a 2-2.4ish cube box?

You could also look at getting 2 smaller amps instead of one large amp. Like 2 of the AQ 1200's or sundown 1500. Then wire the subs in groups of 3 to the amps to get a .7 ohm load which most 1 ohm amps can handle when taking in to consideration imp rise and the addition of a decent electrical system. Its just an option to think about.

Dreadnaut's are awsome subs man, a bit pricey again, but worth the quality. I had 1 Juggernaugt 15 and won quite a bit of trophies with it. Its worth a look.
