I am going through the motions to installing a new system on my 98 tour. My Kenwood bandpass box, 2 Amps, Component speakers, New 6X8 and CD changer and head. But I keep running into new dilemmas every time. There is just so much to be covered! I want to know besides Gold and Silver what is the best metal conductor there is for sound. Also I want to know if my bass Amp pulls 30 amps of power and my mids and tweets pulls only 7. Do I need more than a 40 amp fuse to keep the power save but well powered?
