Ok so my parts all came in and I got the speakers wired, battery and ground to the amp wired, just need to connect it to the stock radio but I don't know how. It's a 2014 Mazda 3 with the touch screen.
You need a LOC. You can get a cheap one but you will have to deal with the factory EQ and low end cut off. Or you could get a Audiocontrol LC-2 and it will override it. That is your best bet. Look up the LC-2 on their website and it will show you what it does.
I don't know exactly, speakers are 2 dual coil pioneer ts-w310d4.
The wiring kit came with battery positive and negative cables, an rca cable, a cable that's exactly like the rca but without the rca endings, and a thin blue wire. I installed everything except the rca, one that looks like it, and the little blue one so pretty much just power cables. Are they two versions of the same cable and I'm only gonna use one?
