Two quick questions and your plan is ready.
This is how I tailor the picks and the budget — no long survey, I promise.
2020 Ram 2500
Your 2020 Ram 2500 comes with 6x9s up front, small dash and center drivers, 6.5s in the rear doors, and no sub — running off a factory-integrated dash you can't replace. Factory amp status is unconfirmed. For a full system build at a premium budget, you're replacing every speaker position, adding proper amplification, and putting a sub in your truck's cab. There's no trunk to work with — bass lives under or behind the rear seat in a compact enclosure built for the space. An integration kit connects the factory dash to the aftermarket amp so the signal path is clean. Front 6x9 components up front, matching rear 6.5s, an amp sized for all channels plus a mono sub channel, and a cab-mounted sub is the complete build for your 2020 Ram 2500.
The upgrade path
4 steps · ordered by impact · with DIY difficultyYour 2020 Ram 2500 has a factory-integrated dash, so a head-unit swap is off the table even on a premium budget — the controls and display are built into the panel. For a full system build with no compromises, a high-quality integration adapter or DSP is the piece that matters, extracting a clean signal from the factory unit so the front stage, rears, amplifier, and subwoofer can all be dialed in around it. On a build this complete, the DSP is what ties the system together and gives you the tuning control to blend every stage precisely. Whether a factory amp is already present is unconfirmed, so confirm it rather than assume. Done yourself, it's a doable step since the adapter interfaces with the factory harness rather than cutting into it.
Why it’s the pick: This is the converter I reach for first on any factory deck that isn’t already amplified. It takes the speaker-level signal off the back of the radio — up to a hot 40V/400W per ch…
Building a true full system in your 2020 Ram 2500 means treating the speakers as one job, not two. Both the front and rear speakers in your truck's cab are 6x9s — see the Best Car Speakers by Size guide for options built to that size. On a no-compromise budget, replace the front and rear 6x9s together now; a full system build doesn't hold any part of the speaker set back for later, and there's no reason to run a mismatched pair in the cab when the goal is the full concert-like blend of bass, mids, and highs. Since this is a DIY job, either pair is a straightforward, connector-based swap with no fabrication needed in the cab. With both pairs matched and in place, the bass and power steps that follow have a properly balanced foundation to build the rest of the system on.
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…
Your 2020 Ram 2500 has no trunk and no factory subwoofer, so the sub goes in the cab — under or behind the rear seat in a custom enclosure built to that driver's specifications. Shallow and slim-mount drivers are made for this placement: they deliver real low-end without requiring enclosure depth that would eat into seat travel or cab usability. At a premium budget, a proper subwoofer in a properly tuned custom enclosure is the correct choice — not an all-in-one powered box. The enclosure volume and port tuning (if ported) make a real difference in how the sub integrates with the rest of the system. The Best Slim / Shallow Subwoofers guide covers drivers built for this exact install.
Why it’s the pick: Shallow subs used to be compromises. Not anymore. Hertz re-engineered the MPS for the slim form factor rather than shrinking a standard design, which is why it behaves like a “rea…
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 2020 Ram 2500 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 2020 Ram 2500'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,…
2020 Ram 2500 audio — common questions
What size speakers fit a 2020 Ram 2500?
The 2020 Ram 2500 uses 6×9 front speakers and 6×9 rear speakers.
What is the best subwoofer setup for a 2020 Ram 2500?
No trunk, so bass lives in the cab — a shallow/compact sub fits under or behind the rear seat, or in a truck-specific enclosure.
Can you replace the head unit in a 2020 Ram 2500?
The 2020 Ram 2500 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.
