Hi,

I've got one of these for my car:

http://www.gumtree.com/london/75/52231875.html

It's rated at 550w RMS and 1600w peak so I was wondering, do I need an 8 gauge or 4 gauge wiring kit.

I like this:

But this is 4 gauge but says it only works with 1200w - will this be suitable for my subwoofer or should I get something else?

Thanks!
