i am new at this whole car audio thing, so i need some advice and guidance. i was ordnally looking into jl w7 12 inch with 1000/1 amps but then someone told me they were over priced and not that great. so i looked into FI's. first off, i was looking into the BTL's 15 inch (probably n2). im not sure if i should get one or two, im not sure if one is gonna cut it. but i also need some advice on good amps, i know which wire kit im getting and i know the high output alternator im getting. and im a little confused on what some of the ohm and what ever do. what does ohm mean and what do they do? i have a choice of either dual 1 or 2. and all i want is someone to point me in the right direction in what i should get. im planning on using theise subs daily, no competions. but i also want these things blowing my windows, while at the same time keeping a budget. and if someone knows a website that make custom boxes for fi subs please list it because i found a website that makes custom jl boxes and they are pretty cheap.
