Hi,

I'm planning on installing my speakers soon and have 2 amps in my setup (1 purchased, 1 pending purchase). I will be going with 1 12" sub (not sure which brand) for my vette, and have the HAT Clarus 61-2 for the front components. I am planning on running an Alpine PDX 1.600 and PDX 1.150 or 4.100 (bridged). I had previously purchased 4ga power cable and would like to use this for the install.

Question: Can I run 1 run of 4 ga power and ground to a distro block and then 4 ga outputs to the amps? I understand that the amps won't really be splitting the power delivered to the distro block, but I just don't feel like buying more wire for this project - I just want to make sure it won't mess anything up.

Thanks for helping - perhaps it's a stupid question, but I'd rather ask first and be stupid than mess something up.

Dave

It never hurts to run oversized wire.

Check out this fun website. Insert the numbers for your equipment and see what it says about the required wire size for your system.

http://www.bcae1.com/wire.htm

If it says 4 ga. wire from the batter is okay, then you dont have to buy new wire. Then look to see what it says for after the distro blocks to the amps. It will always be smaller. I would "think" (but do not know) that using 4 ga. after the distro block would be okay if it says you CAN use 4 ga before the distro block. You will find that the distributed wires are smaller than the main (of course).

The good news is that if 4 ga comes up as satisfactory for the main, then the smaller wire afterwards will be MUCH cheaper to purchase, should you elect to actually purchase any. Much better than if the website tells you that you need to purchase 1/0 ga. for the main.....then things get $$$$.

I run 4 gauge main and 4 gauge to the pair of amps, without problems. The issue is distance. A 4 gauge wire that is somewhat short is going to have the same resistance properties of a longer 0 gauge. How much longer? There's some math there, but you're probably OK as-is w/ 4 gauge.

If the 4 gage wire from your battery is large enough to handle all your amperage then there is absolutly nothing wrong with running 4 gage wire from your disto block to each amp if that is your question.
