Default Wiring Help Plz...

Ok, so I have 2 DVC 400w RMS @ 2ohms subs, and a 2 channel amp rated at 800W x 1 @ 2ohms. I wired the subs by taking the 2 positive wires (and 2 negatives), twisting up the ends, and using a connector to attached them to the terminals in the box.

My question is, should I wire them a different way? (I saw a diagram of attaching one positive to the other positive terminal, then only running one wire to the terminal) If I should do it another way, diagrams would be appreciated. Thanks.

This is how you should wire it up to get 2 ohms: http://akamaipix.crutchfield.com/ca/...2-ohm_mono.jpg

ETA: You can disregard my questions/comments in the other thread because this diagram should be a better representation of how your subwoofers should be connected to your amp!

That connection uses the amp in 2 channel mode, presenting one ohm to each channel. How is the amp rated for 2 channel mode?

If you have a two channel amp, you should wire it like this: http://akamaipix.crutchfield.com/ca/..._2-ohm_2ch.jpg

Unless your amp is 1 ohm stereo stable.

Please provide a link to the amp you are trying to do this with so you don't send it up in smoke by accident. Also, some monoblock amps have two sets of speaker connections so be very careful that you don't present a .5 ohm load to your amp unless it can take it.

Yeah give us a link to the amp manufacturer's page for your model and we can look at the specs.

If it is one of those that gunz mentioned which is mono but with 2 sets of speaker terminals, the way it is connected now is probably going to overload your amp.

Wire your subs series/parallel. then bridge the amp.

I can't see the the12volt diagram without subscribing to that site. I'll assume it is stil hooked up like your hand-drawn diagram. That wiring is not correct for the equipment you have. The amp is loaded to 0.5 ohms and it is not designed for that.

You need to wire the subs series-parallel. This means the two coils in each sub are in series, then the two subs are in parallel (which is done at the amp because the two sets of output terminals are merely connected in parallel internally). This gives you 2 ohms at the amp, in which case it is rated for 800 watts. The power will split evenly between the two speakers, 400 watts each.

If you had four ohm DVC subs, you could use parallel-parellel wiring (like your hand drawn diagram) and have one ohm at the amp, so it could deliver 1200 watts. But you don't. The two ohm coils must be wired series-parallel to not overload the amp.

I used 16 gauge wiring, and I just read the manual sayin 12 gauge minimum :@
