Default Ohm / Resistance

If I have a 1 channel sub that puts out 2000 watts RMS at 1 Ohm, and I want it to power 2 10 inch subs, what Ohm-rating should I look for on the subs?

Would 1 ohm be the best bet so I could get 1000 watts to each sub?

Also, the subs are DVCs.

So would Sub1+ to Sub1+ to Amp +, Sub2+ to Sub2+ to Amp +, and the same way for the negatives give the correct outcome?

Your sub amp puts out 2000 watts RMS @ 1 ohm....correct??

If you want to use 2 subs...assuming single voice coil each...you need to order 2 ohm subs. Wire them + to + and - to - and then connect to your amp. That is wiring in parallel. That would bring your load down to 1 ohm so the amp will put out it's rated wattage.

If your subs are dual voice coil you have a couple options. Get dual 4 ohm subs and wire each sub in parallel...+ to + and - to -. That makes each sub a 2 ohm load. Then wire them together + to + and - to - to bring the load down again to your 1 ohm load.

You could also use dual 1 ohm subs. Wire each sub in series...+ to - between coils. That turns your sub into a 2 ohm load. Then wire each left over + and - to the other subs + and - and that brings them both down to 1 ohm load.

Series option is most difficult if your new into this. My recommendation would be SVC 2 ohm or DVC 4 ohm...wire in parallel and you'll be set.

The power from your amp will essentially be split between the subs. Your subs should be able to handle 1000 watts RMS each. Tough to find 10's for this but 12's are pretty easy to find with that power handling capability. Kicker CVX's and L7's both will do it.

Hope that clears it up....

Hahaha...i had actually found that and was going to try it...

question regarding that...

how do I need to split off the + or - from the amp?

running 2 wires from the positive wouldn't work would it?

I would just pre-solder a harness out of speaker wire.
