Help me finish this build .. I'm lost

[Search 10+ year member]

I am new to this and am learning as I go. Here is where I am.

Got my hands on one of Kickers Loaded Enclosure boxes for CVRs. Got two 12" Kicker CVRs after hearing they were a good bang for the buck.

The box is made to where you wire each sub to one terminal. So I will only have one wire running to the amp.

Each sub is wired in parallel. According to the manual if I wire a dual voice coil sub in parallel it will be 1 ohms.

So.. I went out and bought a Kicker DX 1000.1 which will be here tomorrow (Thursday) night via UPS. It's rated at 1000 watts at 1 ohm on the website. I was thinking, great, now I can hit maximum RMS at each sub and my amp will be safe.

Well.... found out tonight that if I have TWO subs at 1 ohm each it will be a combined load of .5 ohms on the amp. Ok, I'm not an electrical engineer but I can tell this isn't going to work.

So I realized if I wired my sub in series (4 ohms each), there will be a 2 ohm load on my amp. Jump back to google and a few websites say this amp does 500 watts at 2 ohms. So I wasted my money on the amp.

Well I checked Kickers website, and checked their online manual.. This amp is rated there at 1000 watts at 2 ohms. So is this a mistake on some retailers part, or am I missing something?

From what I can gather, based on Kickers information (which is probably right), if I re-wire my subs in series, hook my amp up, and pull my multi-meter out and adjust the gain so I'm getting 800 watts out of it (400 to each sub), I will be exactly where I need to be.

Correct?

I am sure I just answered my own question, but I can't afford to screw anything up so I'm just double checking that everything is done right.

Are the subs Dual 4 or dual 2? The12volt.com has a very good diagram.

Are the subs Dual 4 or dual 2? The12volt.com has a very good diagram.

Dual 2 ohm. I made 2 mistakes:

1) Didn't realize that 1 dual voice coil sub @ 2 ohm = 1 ohm load on amp and 2 dual voice coil subs @ 2 ohms = .5 ohms

Having both subs wired @ 4 ohms would yield a 2 ohm load on my amp.

and

2) The Kicker DX 1000.1 amp is 1000 watts @ 2 ohms.

Where as I was under the impression it was 1000 watts @ 1 ohm.

So now I think I'm good, I just wanted to double check I wasn't missing anything.

So yea, re-wire my sub in series which = 2 ohm load @ amp and wait for the brown truck so I can finally turn this thing on.

Now I just need to find a manual for how to tune the amp.

I don't really know where you are going with this but I will say if you wire the 2Ω coils in series you get 4 Ω's. With resistance in series the resistance values adds up where in parallel the equation is product over sum (2 x 2 divided by 2 + 2 = 1). Basically, if you have two like value resistances in parallel your effective resistance is approximately half the value of one resistor. Two 2Ω coils in parallel = 1Ω. If interested you can go to 12volt.com and read about ohm's law. More resistance = less current flow, less power.

Back to your issue, like you said I hope you did get it figured out.

If you wire them series on the subs then run the two subs parrellel for a 2 ohm load if the amp is 1000 @ 2 ohm u should b fine. I wouldnt put 1000 on them though. I have2 10 inch cvrs great subs but mine r older was running those at 600 rms sounded ok for a truck.Trying to upgrade to 2 l7 12s.
