im new to the whole audio terms thing. i know what subs i want, but they are available in either 2 ohm or 4 ohm. same price for both. what is going to be the difference between the two? and which would be better to get?

it all depends on how many subs your going to get, if they are dvc's, and what kind of amp. Let say your just going to get one SVC sub and a mono amp, you would go for the 2ohm one beacuse you then would get the most power out of the amp. If your were to get 2 svc subs and a mono amp, go with 4 ohm subs then you can wire in parrell and get 2 ohms, unless you have a good amp that can handle 1 ohm in wich case you would get 2 2ohm subs. Do you get the picture? Anymore questions just ask

two svc 4 ohm subs wired in parallel = 2 ohm total load
two svc 2 ohm subs wired in parallel = 1 ohm total load
two dvc 4 ohm subs wired in parallel = 1 ohm total load
two dvc 4 ohm subs wired in parallel/series = 4 ohm total load
two dvc 2 ohm subs wired in parallel = .5 ohm total load
two dvc 2 ohm subs wired in parallel/series = 2 ohm total load
two dvc 2 ohm subs wired in series = 8 ohm total load

Keep in mind that amps that are .5 and 1 ohm stable can be extremely axpensive. A mono amp that is 2 ohm stable is a good investment in my opinion. Even though mono amps only have 1 set of outputs, you can still wire multiple subs to it, making it extremely versitile. Some people prefer to go with a 2 channel amp that is bridgable for max power, but I prefer a mono amp over a bridged 2 channel amp any day. I'm running a Rockford 500bd (mono amp) powering two 4 ohm svc HE 12's. It's close to a 150 db system at near 700 watts. I plan on doubling it in the near future...
