RCA Wires
Amp Wires
Adapter <- Which I can pick up at any store

Is it worth buying these online, considering they're good brands for a good price, or should I buy it at any local store?

 

i would check local stores before i buy online. you might be able to find an audio shop that will cell you the 0ga by the foot. it could end up being cheaper but then you still need to get some odds-an-ends connectors that an amp kit would normally come with. you dont really need the distro blocks or the 4ga wire though...

you dont neccessarily need a two channel RCA kit either. 1 pair of RCA's will work and 23 ft is pretty long. all 3 of mine are 17ft and i still have wires bundled up in the back.

and, dont forget about the wires from the amp to the subwoofer.im not sure what size you would need. my local radioshack hada 20ft spool of 12ga wire for like $4.75. however i only have a 750w amp... the hifonics amp may need a larger wire to the subs

 

I was looking at the stuff at Circuit City but everything was so pricey so I didn't even bother checking Best Buy. I didn't think of checking radioshack, I should definitely check them out. There's a local shop near me called Sound Conecpt that he told me to check out. I might stop by there and just tell them to give me everything needed. I'm gonna buy the amp that I picked out right now though, just so I pay for it. It's the Hifonics BXi1606D
