It depends, if u get a BTL you are goign to have a bigger amp, aswell as upgraded electrical... overall if you need a budget friendly ssytem in a stock car, gt the RE SX becasue of the fact that there wont be nearly as much power running through your vehicle, so you would avoid having to get a bigger alt, or extra batts not to mentiona bigger amp. But if you get the SX if you find an efficient amp, you could get away with stock alt (depending on car) a good batt undr the hood, and the big 3.
