IA 40.1, optima, nsb90, 250A alt, still not enough,

When referencing the 20.1 only having one and the 40.1 having two, those are for the power and ground wires. You only need to hook up one but the amp will be more efficient if you use both.

The 40.1 has dual 0 ga inputs since it will draw in excess of 450 amps. 0 ga is usually only good for 300 or so amps. (yes short run, blah, blah, blah) that is why there are two power inputs.

Mono does mean one channel that is correct.
Your 40.1 is a monoblock. Says so right on the box. The only reason there are two speaker inputs is for convenience of wiring multiple subs. They are internally bridged together.

If you hook up two ohms to each channel the amp will see one ohm.

If you hook 4 ohms to each, the amp sees 2 ohms.

1 will see .5. Make sense yet?

Explains completely. Thanks alot bro. So I need to wire them to 4 ohms and then it will see a 2 ohm load.

But I wish I would have know that b.c that is only 1800 watts. I could have gotten that out of my mmats..

Anyone want a 40.1? lol

Or I could buy them 4 ohm recones and use them to make a 1 ohm load.

Just series ur subs wiring and run them to the amp like normal....BAM.....2ohm

Get a voltmeter and mount it to the dash. If you see that voltage dropping too low, it's probably smart to go a little easier on the volume knob.

That is still only 1600 watts though.... I was wanting more like 4000

It will be more than 1600 watts assuming box rise isnt too out of control. I promise. It may not be perfect but its the best option for right now.

But seriously. Get the dds reconed to dual ones. You will be happy.

Well if u werent having problems id say .5 it asap....i would but im not u

I think that was a combination of no big 3 and a shitty ground for the rear battery though.

I could do the dual ones and let the amp see 1 ohm or dual 4 and let the amp see 1 ohm. I can just get dual 4 recones for 100 dollars..

Yea I think the ground was to long plus it was just on the seatbelt bolt.

Yeah at the very least ground it directly to the frame. Drill hole in floor, bolt directly to frame rail with bolts and lock washers. Or run it to the front battery.

Yes dual 4 would work as well.

If your wire is properly sized, a ground with a little bit of extra length on it isn't going to hurt much at all. That current has to flow a pretty good distance to the front battery anyways.

Correct. But grounding to a seatbelt bolt isnt a good ground no matter how long the wire it.

With that much current anyways. You can probably get away with it on under a 1000 watts but I still wouldnt recommend it.

No big 3 wouldnt kill an amp

Prolly just beat the crap out of it and excessive low voltage killed it, big3 wouldnt have helped nor did it hurt not having it
