So i recently have purchased some 6-1/2" Alpine Type S components to replace my front two speakers, and 5-1/4' Alpine Type R's for the back two, but have no idea how to go about this job or what to do about the factory mounting brackets. I want to do the job myself, about 6 months ago i installed a Pioneer Premier head unit, an alpine V-Power 450W mono amp, and a kicker L5. I have another Alpine V-Power 4 channel amp for the speakers, a rockford fosgate farad capacitor, and speaker wires. has anyone done this job themselves and have any tips/things to watch out for/ or even how to go about this at all?
