2019 Chevrolet Silverado 1500
Your truck's factory audio runs 6x9 front speakers off a replaceable head unit, with no factory amp and no sub in place. On a premium, no-compromise budget doing the work yourself, the goal is the whole system at once: new front 6x9 speakers, a proper amplifier sized to power everything being added, and a subwoofer built into a custom enclosure sized for the cab since there's no trunk here. A sub tucked under or behind the rear seat, or built into a truck-specific enclosure, keeps bass tight without stealing cab room. There's no reason to defer anything on this budget; the head unit swap is straightforward here too since the dash isn't locked down, so the full build, speakers, amp, and sub, can go in together.
The upgrade path
4 steps · ordered by impact · with DIY difficultyYour 2019 Chevrolet Silverado 1500's double-DIN opening is the right starting point for a full system build — it means a direct head-unit swap with no fabrication. Since there's no factory amplifier, the head unit's preamp outputs go straight to your amp, so the quality of those outputs matters: look for a head unit with multiple preamp outputs at 4V or higher to feed front, rear, and sub channels cleanly. A vehicle-specific installation kit from Metra or Scosche covers the dash fit and wiring harness. Make sure the kit includes a steering-wheel control interface if your 2019 Chevrolet Silverado 1500 uses those buttons — losing them on a daily driver is a real inconvenience, and retaining them is a straightforward addition.
Why it’s the pick: The DMH-WT6000NEX is my big-screen value pick because it puts a current 10.1-inch 1280 by 720 floating display under four figures without gutting the feature list to get there. It…
The speaker stage is the front-line of your full build, and your 2019 Chevrolet Silverado 1500's cab layout gives you solid real estate: 6x9 front doors and 6.5 rear doors. Put component sets in the 6x9 openings — a woofer in the door, a tweeter mounted near the A-pillar — so you get a proper front soundstage in the cab. Coaxials placed low in a truck door don't image well; components with proper tweeter placement fix that. The rear 6.5s get replaced now too, not later. In a full build, all zones are upgraded before the amplifier wiring begins — you want to tune a complete speaker stage, not add speakers around a wiring job that's already done. Get everything in, confirm it, then run the amp wiring.
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 truck starts with the physical reality: no trunk, so the subwoofer lives in the cab — under or behind the rear seat in an enclosure built to that sub's specs. A shallow or compact sub is designed for exactly this constraint; the box tuning is what separates controlled, musical bass from a muddy cabinet resonance. Because you're doing the install yourself on a premium budget, build this step the right way — a proper subwoofer, a custom enclosure, and a dedicated amplifier. That combination integrates with the upgraded front and rear speakers you're already running to deliver a cohesive, full-range sound in your truck's cab. See the Best Slim / Shallow Subwoofers guide for truck-friendly picks.
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…
With no factory amplifier in the 2019 Chevrolet Silverado 1500, everything downstream depends on what you add here. For a full system build — speakers across all zones plus a subwoofer — the amplifier (or amplifiers) is the core of the system. Head-unit power isn't designed to run more than a basic speaker pair cleanly; adding a dedicated aftermarket amp with proper gain staging is what makes the speakers and sub sound like a system rather than a collection of parts. Size the amp to one channel per speaker zone plus a mono channel for the sub; a single large multi-channel amp or a multi-channel paired with a mono sub amp both work. With a replaceable double-DIN head unit, the preamp outputs feed the amp directly — clean and simple.
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,…
