How to wire two 4 ohm DVC subs down to 1 ohm?

[middlemaniac 10+ year member]

Can someone give me a really good diagram showing how to make two 4 ohm DVC subs go down to 1 ohm. Thanks. PS i've looked on the internet, and different websites have different diagrams for the same thing for some reason. So I just need a legit diagram that will work. I am wanting to connect two 4 ohm DVC subs down to 1 ohm into my Polk PA600.1 mono amp. Also it is ok(maybe not the best) to use good quality 8 gauge wire to power the 600 watt RMS amp right....?

It's fairly simple

Each woofer has two positives, two negatives, right?

JOIN the positives together, and the negatives together on each woofer

Run a jumper from pos to pos and neg to neg on each woofer, got that. Next, run one pos one neg from each woofer and join the two woofer's positives and negatives together then wire them to the amplifier. One ohm load.

is this a good diagram? http://www.rockfordfosgate.com/rftech/woofer_wizard.asp?submitted=true&woofer_qty=2&woofer_imp=4

and it is ok to use 8 gauge wiring to my amp right....

yes, and 8guage for speaker or power wire? and what amp?

Polk PA600.1 mono amp

8g for power will probably not do.

well the thing is that everything is already all wired up in my car with 8 gauge wire.....the wire says it can handle up to 1500 watts, it is by audiopipe.....can someone else give me there opinion on using 8 gauge

8 gauge for power wire is a no-no, at least bump it up to 4 guage

is it that big of a deal to change it if it is already at 8 gauge? Will the 8gauge work????

For only 600rms it should be ok, but you would be better off upgrading to 4 gauge.

will there be a big difference in sound? What is the major benefit to going to 4 gauge if the amplifier is only putting out 600 rms? Is it worth the hastle of switching it?

Well without actually looking around for the voltage drop calculator, if your running too much power for the wire to handle, you'll experience a significant voltage drop, which will result in a db loss. But like I said, I didn't actually look for the calculator so I have no idea if you'll be seeing a voltage loss.

I had a place wire my car already.... would it be a hastle(exspensive) for them toswitch out 8 gauge for 4 gauge? Is it easy to switch out?

found it anyway...

number 16 has the calculators you need

EDIT: 8 gauge is borderline too small. If your alt charges at 13.8 the calc says it's too small, if it charges at 14.4 then it says it's ok. This is assuming a 15ft length, with a class D 80% efficient amp.
