2019 Ram 3500
Your 2019 Ram 3500 has a factory-integrated dash screen that's part of the vehicle's control architecture — it stays in place. What's behind it: front 6x9 door speakers, 3-inch dash tweeters, rear 6x9 door speakers, and 3-inch headliner speakers, all on factory power. For a full system build at a premium budget you're doing yourself, every zone gets upgraded in one pass. The integrated screen gets a signal adapter to pull a clean line-level output; an aftermarket amp drives all four channels plus a dedicated mono channel for the sub; and the front and rear speakers both get replaced with proper aftermarket sets. The sub goes in the trunk — your 2019 Ram 3500's sealed trunk is purpose-built for a sub enclosure, and it keeps the bass load entirely out of the passenger cabin. Build it all at once and tune it as a system.
The upgrade path
4 steps · ordered by impact · with DIY difficultyThe 2019 Ram 3500's dash screen is factory-integrated — it handles audio, navigation, and climate in one unit, and a head-unit swap would break those functions. The right move is a vehicle-specific integration or line-output adapter that taps the factory system's audio outputs and converts them into a clean signal your aftermarket amplifier can use. Metra, Scosche, and iDatalink make kits specifically for setups like this — many also preserve steering-wheel controls so you keep full factory functionality. Because the factory amp status is unconfirmed on your 2019 Ram 3500, check whether you need an active or high-level input adapter versus a passive line-out converter; your installer or the product compatibility listing will clarify. Get this step right and the rest of the build — speakers, amp, sub — all connect cleanly downstream.
No head-unit swap here — your factory screen stays. The right vehicle-specific integration adapter for your build is matched in a later step of the rollout.
A full system build on a premium budget means all four positions now — no half measures. Your 2019 Ram 3500's door openings take 6x9s front and rear, with 3-inch fills in the dash and headliner. For a proper build, go with a component set up front: separate woofers and tweeters give you the ability to aim the tweeters for a focused soundstage, which is where a full build separates itself from a basic swap. In the rear doors and headliner, solid coaxials round out the system. Since you're doing the work yourself and you're building this out completely, do every position in one session so you can set up the whole system as a unit — crossovers, placement, everything. See the Best Car Speakers by Size guide for the specific picks.
Why it’s the pick: If you want a “drop-in and immediately better” upgrade, this is the one I keep coming back to. The RCX-690’s airy highs and tight, realistic mid-bass make factory systems sound mo…
A full system build in a sedan needs real bass foundation, and the 2019 Ram 3500's trunk is the right place to build it. Skip the all-in-one powered sub — choose a quality component subwoofer, have an enclosure constructed to its manufacturer's recommended specs, and drive it with a dedicated mono amp. Done right, the bass from the trunk integrates cleanly with the front stage instead of just thumping independently. As a DIY install, keep the mono amp in the trunk near the enclosure to minimize power and signal cable runs. Getting the enclosure volume right for the sub you choose is the single most important factor in how it performs.
Why it’s the pick: JL’s W7 has been the reference standard for two decades because it blends control and command: deep extension without bloat, slam without smear. Its W-Cone assembly and OverRoll s…
For a full system build at a premium budget, an aftermarket amplifier isn't optional — it's the engine of the system. The factory amp status on your 2019 Ram 3500 is unconfirmed, but the answer is the same either way: the new speakers and subwoofer need clean, properly rated power, and the factory system can't deliver it reliably. Plan one channel for each speaker in the build plus a dedicated mono channel for the subwoofer. That can be a single multi-channel amp with enough channels, or a stereo amp for the speakers and a separate monoblock for the sub — both are legitimate depending on the power ratings you're matching. Because the 2019 Ram 3500's head unit is integrated, signal gets to the amp through an integration adapter. Match the amp's RMS output to the speakers' ratings and you'll have clean headroom across the board.
Why it’s the pick: If you’re keeping the factory head unit or a factory-amplified system, the D-Series makes life easy. Active speaker-level inputs and signal summing handle odd factory crossovers,…
2019 Ram 3500 audio — common questions
What size speakers fit a 2019 Ram 3500?
The 2019 Ram 3500 uses 6×9 front speakers and 6×9 rear speakers.
What is the best subwoofer setup for a 2019 Ram 3500?
For the trunk, an all-in-one powered sub is the easiest big win; a slim/shallow sub keeps more trunk space, and a component sub + box delivers the most output.
Can you replace the head unit in a 2019 Ram 3500?
The 2019 Ram 3500 uses a factory-integrated screen, so the move is to keep the screen and integrate a clean signal with the right vehicle-specific adapter — not a head-unit swap.
