I got the Alpine Type R components 6.5 inch and Alpine PDX 4.100 amp. I am still looking for a subwoofer and another amp for the sub.

Was wondering if this speaker wire kit would work for my set up?

Do you need 20 feet of RCA cable?

Your better off finding an amp kit that does not have RCAs, [buy RCAs that are the correct length] and make sure the kit has an ANL fuse holder, not an AGU.

Unless your amp power lead is going to be longer then 8' you can use 8ga power cable for the 4ch amp, add a 4ga power cable when you add the sub and amp. 94

 

AGU fuses break very easily, especially when they are running in the engine bay of the car.
