for the 6 speaker base (either w/ANC or without) I highly recommend taking audio directly out of radio sending it to a JL Audio FIX 86 processor which does a really good job of flatting out levels and provides nice clean signal for your choice of Amp(s).. This is nice set-up retaining all your factory radio controls giving an aftermarket effect.. When installing aftermarket speakers, the radio will need to see a load specific to factory speakers.. I used this Harness
https://www.netaudiowf.com/product/2013-18-dodge-ram-radio-t-harness-with-load-resistors/ with load resistors, which also gave me an easy way to splice into my speaker outputs.. Trust me folks.. the factory radio will perform at a professional level. Build it right and you will be happy
I will update my final layout in this post when I’m done but
@kirkelli is right. Short(ish) story.
I have the stock six speaker speaker. No amp. No sub. But I do have a hemi, therefore I have the ANC.
Upgraded all the speakers to infinity ref. Much happier. Ran into ANC problems. Decided I didn’t want to be bothered with it and didn’t need it, so I unpinned the ANC mics (plus at that point I knew I wanted to add an amp and a sub)
Was still looking for more punch and more bass so I decided to add a pioneer amp to drive the speakers and a self powered sub (built in amp) for some more bass.
For equipment I wanted to keep costs down, didn’t need anything too elaborate, wasn’t looking to get crazy. Otherwise I would have run all new wire, added mids/tweets, etc. Since I wasn’t interested in going that route and only adding some power and bass I decided on a Pioneer A-GM6704. For a little over $100 this gives me high level inputs so I didn't need a separate Line Out Converter (LOC) and given it’s just the base system and wasn’t adding mids/tweets etc, I decided I didn’t need anything with DSP or summing. Some would argue this was stopping short of doing it right but again I wanted to keep costs down and things as “simple” as possible. This amp also has a Bass boost function which should handle any bass roll-off. Not sure if our base 6 speaker systems roll off the bass when volume increases but just in case, this adds the bass back (like the Lc7i and Fix, etc).
I then went with a Kicker self powered (built in amp) Hideaway sub.
Neither of these will fit under the front seats so I am removing the rear seats and mounting them to the rear walls.
The most frustrating part of the long process so far, I’ve gotten frustrated and sidetracked with this process for months, wasn’t the speaker install or disconnecting the ANC (which were both a pain at times) but it was the wiring of the amp due to what was mentioned above. Since I no longer needed the ANC, I decided to just remove the unit entirely and just tap into the two harnesses that are left once it’s removed. One for the speaker inputs (from the head unit), one for the outputs (to the speakers). These will feed the new pioneer amp. This next item is what frustrated me and got me hung up so excuse the caps YOUR AMP WILL NOT WORK UNLESS THE RADIO SEES “A LOAD” WHICH MEANS YOU NEED RESISTORS ON YOUR WIRES/HARNESS. I can’t tell you how much time I wasted not paying attention to certain posts here and not understanding what that meant. So you either have to use a harness like the one kirkelli posted OR solder in some resistors to each of the speaker wires coming out from the head unit (large white harness under driver’s seat). I will post the ones I purchased below and will try and post a more complete write up when I’m done. For now it’s tested but now I have to button everything up.
EDIT: one other bonehead mistake I made that cost me tons of time troubleshooting. You can’t just test one speaker (two wires) with the resistors. The head unit has to see a load on all the speakers otherwise it won’t put out a signal (only distortion/buzz). So put a resistor in-line on each speaker wire coming from the white harness, into your amp, 8 in total (or just buy the harness kirkelli referenced above which already has the resistors built-in.
