i have a 300x1 @ 4ohm and 600x1 @ 2ohms, i wanna hook it up at 2 ohms what gauge wiring kit should i get?
well,i didnt know what kind of amp that you have,so probably its true 300w or not. but my suggestion is for your own equipment safety you should use min. 4 ga with 50a, coz i see here you try to bridge it. try tsunami they good and real 4ga if they said 4ga.
if it is a class d then 4 gauge should do up to about 18-20 feet. I don't know of any other type of amp but that should do it.
Your link isn't complete. One thing I do know, many cheap speakers come with speaker wire that is about the size of a hair and practically impossible to do anything with. I just buy 18 or 24 guage wire in a spool to hook up the speakers. Using the next size wire doesn't hurt, but smaller wire will reduce performance.
I am pushing about 1000 watts through my wires...I use the lowest gauge (biggest wire) i could find, which was 2 gauge. Before, i used 8 gauge power/ground wire and 14 gauge speaker wire. I re-wired my truck with 2 gauge power/ground wire and 8 gauge speaker wire.... MUCH more punch and substantially louder playing levels. I lost lots of power through my previous wiring. Lots of ppl argue with the wire size, but i say go lowest gauge possible. I mean, its makes sense.....the bigger the wire, the easier the electrons can flow through.
