Relevant, but not brand specific info inbound.
One of my requirements when I got my ram was that it have bluetooth for music and calls, I frequently get calls after I drop my youngest off for school in the mornings, so it was almost a safety feature for me. I also had a problem of one of the on-speaker amps being blown - shit design IMO, but it's a 98 Dodge, so...
I ended up pulling new heavier gauge wire through the accordions at the doors, replacing all four speakers, bypassing the OEM tweeters, adding a five channel amp, and an 8" sub in a sealed enclosure that tucks under the driver's seat, and I did it on the cheap. I used kicker speakers with decent frequency response and decent power handling, a boss touch screen head unit with a floating screen - this let me keep the single DIN adapter that was in the truck, and I love that I have the adjustment on the screen, it angles at me, it's easy to see, low enough that it never glares, and if it does, I can change the angle. It fills the space really well.
I used this head unit:
Boss Floating Ten Inch Screen and a Planet Audio Five channel Anarchy amp. Be aware that the internal amp on the boss head unit is complete garbage, and couldn't get the kicker speakers loud without massive distortion. The Planet Audio amp is a bit overkill for my speakers, but it means I'm running it at less than 20% gain, and it gets louder than I want to hear it without any dirt coming through.
Recently, the bluetooth has started cutting out after three minutes on a call - read online and found it's a fairly common problem with Boss bluetooth decks, so I'm looking for a replacement that has a similar sized floating screen - I know it will cost more than the boss did, but I've really fallen in love with that feature. First pic is right after I installed the deck, and the second is after I changed the dash cover to the black non glare one, but shows the angle from closer to the seated view.
Right now I'm debating doing a rear seat delete on the truck, building a custom storage box with an integrated 10" sub in a small sealed enclosure, and a top deck spot for a pair of 6x9s. If I do that, I'll take the 6x9s out of the front doors and replace them with componant 6x9s in the front stage, with the tweeter set in the door card instead of the pillars, same place as the tweeter in the 94-97 trucks. I'd love to find a pillar gauges pod that included a grab handle for the drivers side, and I know there's not a hope for that with the OEM tweeter on the pillar and three gauges.
