Wire for Big 3

[aarunt1 10+ year member]

I want to do the Big 3 but don't have a car audio shop close by and they are always expensive. I went to home depot and lowes and they pretty much have the same kind of large gauge wire. They have a copper wire THHN that goes as big as 3/0. I was thinking about getting the 1/0 which is rated at 120 amps but it actually looked more like 4 gauge in terms of actual wire and the strands are super thick. They also have this other wire called aluminum urd which comes in 4 gauge and is rated at 200amps. Looking at other large subwoofer wiring, it is always a silver color like this: Elemental Designs

So should I just go with the aluminum urd 4 gauge?

Let me know. Thanks!

mostly anything like that will be an upgrade from stock but why not just order online???

It's not worth it to me to buy it online with shipping when I can just get the stuff at home depot for half price. I'll have to check eBay.

knukonceptz.com They have every thing you need shipping is really reasonable and fast. Every time I placed an order I received it within 2 days.

They're wire is a pretty good price but I was expecting the ring terminals to be cheaper : /

i'd like to see a link to AL 4awg rated for 200A. AL wire has lower ampacity than CU wire.

Ouch. How is that 1/0 rated for only 120A? And the 4 rated for 200...?

I used KnuKonceptz KLMX for my big three. Very inexpensive and I only used 4 gauge since my alt is rated for only 90 amps.

I wouldn't use the Knu ring terminals; first, because they are expensive, and second, I find traditional ring terminals difficult to work with. I prefer lugs, such as these... Impulse Electronics - Eyelet Terminals

They make soldering very easy.
