After much research, anxiety and general farting around I've decided it's time to put a decent sound system into the Ranchero. As such, I'm going with this setup: RetroSound Zuma headunit JL Audio C2-690tx coax three way speakers JL Audio JX360/2 amp Absolute 2SW6X9 speaker boxes for behind the seats All total, this will come in at right under $500 which is not bad given the JL Audio gear which is top notch. Here's my questions for anyone who may have already gone through this. 1. What route have you taken to tie in the amp cabling to the battery? 2. What size alternator are you running and did you change that out? This is of particular concern since now that I have my voltmeter working I have noticed that there is a drop in voltage when the headlights and turn indicators are on while idling. Maybe this is normal. Currently I have a 55amp alternator. 3. What exactly did you have to do to tie in your head unit? Did you bypass factory wiring or use it? As always, thanks is advance and feel free to comment.
