    The Fascinating Evolution of Automotive Wiring sorry if this has already been posted
  2. Fabrication, Tools & Tricks of the trade
    Here is a link to a ton of compiled information on mil-spec motorsports wiring. It also shows a lot of wiring tools that you probably didn’t know existed. Some of you will think this is completely overkill, but a lot of what we’re doing in SQ car audio is overkill anyways. I recommend that you...

    I've got an aftermarket HU going to a 4 channel amp split to front speakers and rears are bridged to a sub. I play the system loud as it's in a 4 season door/roofless Jeep Wrangler and it's always up against wind/road noise. After about 6 months with this setup, the amp has been shutting off...

    I need a little reassurance from someone smarter than I am. lol I'm currently in the process of wiring the Helix Director. I have an LLJ Custom Harness that comes from the factory radio that goes into the Helix V8. This harness also has a "Constant" 12v + Ground up to 7 amps and a remote wire...

    So, I looked into it a little bit and it seems like it should be possible to tap into the wires behind my head unit to power my door speakers and tweeters with an amplifier. My questions though, do I need to still connect those wires to the head unit? And will it cause an issue for the tweeters...

    Hi all - I have the above truck, it has an 8" touch display which comes standard in them, no Bose. I completely wired by 2008 Impala by myself. I put an aftermarket deck in it with three RCA outputs, easy. This Silverado obviously doesn't have any RCA's coming out of it and I need to use a LOC...

    I have done a forum search prior to posting and did not see any recent results relating to my question. Due to a new job and significant commute, I have both fortunately and unfortunately found myself in a 2013 Prius, a downgrade from my truck with a system that I loved. I am currently...

    Can someone please make this make sense? I understand that the type of signal transmission has a profound effect on sound quality and that being said based on popular opinion by degrees of quality it goes in order from LEFT(Most poor) to RIGHT(Highest standards) as follows...

    Hi, I just bought a new pyle subwoofer with a power akoustic amp. I changed them because my last setup was acting strange.

    New guy here. I recently installed a Rockville powered 12" sealed sub box in the trunk just to give my stock system a little missing low end. For what it is, it actually gets the job done. I got everything dialed in and it sounds pretty good. However, I can't run it too long before the thermo...

    I recently bought a new car (1988 Nissan Prairie) to eventually replace my 2002 E46 Estate. I bought a new radio to put into the Prairie and rewired all the plug to make it work. When plugging it into my BMW it fully boots and screen comes on allowing me to select different options, etc. But...

    Just had a quick question. I have always ran aftermarket head units but I am getting ready to purchase a 2017 Chrysler 300C and want to keep the factory touchscreen in the vehicle.
