I have one amp that recommends using a 4 gauge power wire and ground (Alpine PDX-F4), and another smaller amp that i would prefer to use 8 gauge power wire on.

Can I split a 1/0 gauge power wire into a 4 gauge and an 8 gauge wire? If so can I use the 1/0 to 4 distribution block and just use a smaller 8 gauge wire in one of the output screw holes? Or how should I do it?

Also, will a large power wire like a 1/0 gauge cause more of a drain on the car's battery or alternator than a 4 or 8 gauge wire would? My current car has a weak factory alternator/battery setup, so I'm concerned about using the 1/0 gauge power wire for that reason.

And finally, is it really important to use the manufacturer's recommended 4 gauge power and ground wires on the Alpine PDX-F4, or would 8 gauge be fine?

Thanks

Yes. You can find D blocks with 4 and 8 gauge outputs. 

No larger wire will not cause more draw.

Pretty important to use the correct size wire. Don't want to draw too much amperage and cause a fire because the 8 gauge wire couldn't handle the amperage.

 
Thanks for the response, I should have searched for D blocks before posting. Looking now.

Awesome thank you 1aespinoza. It seems simple but I just wanted to make sure I was going about it the right way.

Nope, just purchased and received it for my brothers "74" Ford Currier truck resto build. Small 4 cahnnel taramps and a set of nice 6.5" Pioneer Z...
