How To.... US Amps MD3D

Hi, I'm Aruman and I'm new on this forum and have some questions.

The problems is that I'm a bit confuse how to Wiring two US Amps MD-3D Using the MLT Wiring as shown in the Owner manual( pics,link below)The problem is that the owners manual says the lowest Impedance is 4ohm, so that means each MD3D should see min. 2ohm, now since I have 4x RE SX 12" Dual 4, 2 subs on each Amp at 1ohm, it confuse me, because if so than the min ohm should be 2 ohm for the MLT Wiring, but they recommend 4ohm min.

And if i wired the subs in series so the final ohm is 4ohms then the subs won't get the full power they should get.

So can I wiring them at 2 ohms final ( 1ohm each amp) and still using the MLT Master/Slave Wiring, or should a set each Amp apart, or there's other way?

Here's the link: http://s109.photobucket.com/albums/n47/Aruman/?action=view&current=USAmps.jpg

Anyways thanks,

Aruman.

 
Ok first of all I have wired these up many times strapped at 1 ohm, you need to make sure your electircal is strong.

Ok to strap the amps. Take a single RCA, from the master amp go from the MLT out to the MLT in on the slave. Ok next it does not show but do it, just trust me on this take a single run of speaker wire meaning a postive and negative and connect the 2 negative speaker outputs on each amp together, with the same gauge wire that you are running to your speakers, preferrably 10 gauge. Then the 2 positives on the master amp loop them together and that becomes your postive out to your subs then on the slave amp loop the 2 postives together and then that becomes your negative to your subs. Hope that makes sense..

 
ok thanks, I've just seen the one on SSA forums, now for wiring the subs in the box PIC 1 (link below)should be the best way to wiring them? If I wired them this way will each amp see 1 ohm automatically thus producing it's rated 2000wrms, thus using one lead wire for positive (master)and one lead for negative to the positive (slave) wire to the amps. is one run of 8guage enough for the 4 subs?

Or PIC 2 will work also or not?

PIC2:

thus using two lead for positive to the positive Master and two lead for negative to the positive Slave.

hope you guys understand what i mean since I'm not so good in English.

Anyways thanks.

Aruman.
