Is this a decent kit?

StreetWires 4 Gauge ZN1 Series Single Amplifier Installation Kit

Its for an AQ 1200d. I just want to make sure this wire is real 4 gauge and will work with 120amps. Its the cheapest kit I found with a 150amp fuse included besides those cheap ebay kits. I hate to spend 60 bucks plus another 10 for shipping for the KNU Kolossus kit.
