97 mustang...5x7 fronts. Its gonna need new kicker panels because of lack of depth. Thinking about getting alpine's newer type X series 6.5" components. My infinity kappa's up front are 90w rms, 270w max, 2 ohms, 46hz-21khz. The alpines are 100w rms, 300w max, 4 ohms, 31hz-40khz. What kinda sound upgrade would you think I would get? Worth the hole process? It also involves getting a new amp, which im ok with, cuz my backs are running on 2 ohm an needs 4 as well
