First off, what exact year make a model.
Like me, a 2019 Bighorn night edition. 8.4 non-navi.
Under the drivers seat has the ANC on these trucks. (Which I thought most came with this) 2500 and 3500 are different. Under that seat you will have a harness available for your speakers an a easy tie in spot. You will have to take one side (feed side) an feed that to an amp, being very careful not to confuse the polarity.. positive an negative… other wise you’ll get speakers out of phase and sound hallow. (Out of phase meaning: you send a signal to all speakers, but one speaker will push out, while another will pull in to make the same sound. You want all speakers working together, meaning all push out an in at the same time)
They DO make small 4-ch amps… where I would advise running the doors off the amp at this point an front speakers off the head unit.
Picking speakers you do want something of quality, but making sure they are super efficient speakers for that dash. This is the whole 1watt gets you what SPL. Higher That number, more efficient speaker, meaning it takes less power to run them. Our factory decks only have so much power.
Something to consider… crossover settings. Your amp will have high and low pass, an it will cut the speakers at some point. You want to try an match this with your dash speakers. Being the 3.5 can only handle so much bass, running them full band would be bad. I advise getting base blockers or a simple cross over to keep the lows away from them. In the instructions for the 3.5’s you’ll also find a useable frequency range. Example 80hz-20hz. So, I’m essence you would want a quality capacitor to block 80Hz an lower frequencies. Or they will distort pop an fart. My guess is that they cut the lowers at around 250 or some place. I could be wrong. I don’t think these decks have internal networks (cross overs) to make this happen.
The factory deck should have enough power, an this way i mention is more easy then using 6ch amp an active stuff. But up to you. Using an active network like Rockfords DSR1. Which may not be a bad choice. Just saying.
Small foot print amps. Kicker makes some, Rockford fosgate makes some, wet sounds, honestly so many make small foot print amps. I personally have a 800 @ 2 ohm amp under my drivers seat, an it does not interfere with my seat at all. Base 6 does not have a subwoofer. So, I opted for the factory box! Yup, works great!!
Just need to match the ohm’s with the amp! In this case, at the 6 ohm load, I end up having about 190 watts. Which is more the. That sun will see off the factory amp. I do plan to install a custom subwoofer box when I find the time to make mine.
I can try my best to help, feel free to message me.
Three options… keep it stock, keep it simple, or go all out. I’m trying to keep it simple side of things for you. Audio file or not, Good sound is what we all are trying to achieve on our beast’s!
