I want to upgrade my sounds due to the alpine system lacking ear numbing quality lol. My plan is to install 2 amplifiers(one for highs and one for subs). In order to do this is the factory amp eliminated? I'm sure the stereo shop where I'm going to take it to get it done should know but I would like to know what's going on before hand so they don't try to scam me adding stuff they don't have to(never trust anyone). Any suggestions to do along the process?
Ps. I will also be adding an epicenter
