I want to put in a descent system in my car. I have a 2.0 cubic ft box for 2 10" woofers. I need a 2-channel amp. I'm looking to get 2 subs that are 700-900watt RMS. I don't know what kind of amp and subs to get. I am confused on the ohms for amps and subs. Do the ohms on the speakers and amp HAVE to match? i'm looking at 2 audiobahn amps
1600watt amp(audiobahn) * 2 x 200W RMS @ 4Ω
* 2 x 400W RMS @ 2Ω
* 1 x 800W RMS @ 4Ω
& 1600 watts RMS @ 1 ohm bridged mono
(whats all this mean? 400 watts RMS x 2 @ 2 ohms
200 watts RMS x 2 @ 4 ohms
and i am looking at a 2 450watt RMS subs that are 4 ohms.
what kind of subs can I get? should i try to get 2 ohm woofers instead? whats the difference? will it be cheaper for me? I plan on spending up to $300 on an amp. Can this work if i plan to spend that much. Can anyone help? I would greatly appreciate it.

The best way to learn is to research what you want to know. Have you done any? By the way don't say the audiobahn word too loud around here.
A "decent" sound system would require, at the least, a good head unit, component (or good coaxial) front main speakers, a two channel amp for those speakers, one sub (or two if you wish), and a class D mono amp to power the sub. Match the sub total wired impedance to the amp's output rating: such as, two SVC 4 ohm subs wired together to make 2 ohms connected to a mono amp that outputs enough power into 2 ohms to power the subs. Look along the left side of this page for info on wiring configurations, links to other info, etc. Take your time...don't make hasty decisions (esp. getting rushed by Ebay time limits!)...buy as much quality as you can afford now instead of later...
We all have inferior gear sitting around that we installed and removed when we realized their shortcomings.

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.
