fosgate = dirty power from their amps. Use 1/0 and trim the wire. That way it'll save you money in the future if you have to upgrade.

 

For a custom box with nothing fancy you are looking at under $200. Go ported, built to spec.

 

You live in the GTA, have someone on here build you a box, much cheaper and same effect. Run 0 gauge, then there is room for upgrade later on and you dont have to cut wire, just buy reducing adapters. I got mine from Tsunami and cost me 8 bucks a piece.

 

also, does anyone know what kind of wire/how much of it/any good deals i would require to do the BIG 3 upgrade? i got a quote from selective sounds,150$ for the big 3 upgrade and 250$ for 50 ft of 0 gauge wire for the big 3? is there a better price? and also does anyone know any good shops that install alternators? im getting a 200 amp alternator from Nate @ excessive amperage

 

I would do the 1/0 as well... then a distro block (1/0 in to several 4ga. out) your 4ga will only be short runs... if you can afford to it is also a good idea to run another 1/0 for a ground directly back to the battery (I was lucky enough to have someone toss me a piece for free). If you want a better price on the wire, check with a welding supplier. I think the last I priced it was $3.49 a foot for 1/0. Buy the raw cable and maybe put out a call for some used top posts/ fuse block/ distro block and 1/0 ring terminals (you'll need a bunch to get the big 3 done anyway)

And remember, the reason you are laying the bones down properly in the first place, so that you won't have to do it twice once you realize you want to add more amps to help your high end keep up with the low.
