Bass Subwoofer Package 5th Gen Under-Seat 1 Pair 12″ Ram 1500 Crew Cab & Quad Cab | 5th Generation New Body | 2019–2026

Ram 5th Gen Under-Seat Dual 12″ Bass Subwoofer Package Ram 1500 Crew Cab & Quad Cab | 5th Generation New Body | 2019-2026 The fully redesigned 5th Generation Ram 1500 — introduced for 2019 — brought a wider, more open under-seat cavity that finally gives serious car audio builders the room they need for a dual 12-inch under-seat bass system without compromising rear passenger comfort or legroom. This complete package was hand-curated by the experts at Breakers Stereo and Performance — with over 50 years in the car audio industry — specifically around the 5th Gen Ram 1500’s new interior architecture, using a vehicle-specific down-firing dual 12″ enclosure with 1.75 cubic feet of precision-tuned air space that fits clean under the rear seat with zero modification required. Pair that enclosure with the Alpine S2-W12D4, the Memphis Car Audio PRX1000.1v2 monoblock amplifier delivering 1,000 watts at 1 ohm, and the Memphis 4GKIT complete wiring kit — and you have a turnkey bass upgrade that installs cleanly, sounds exceptional, and disappears completely beneath your rear seat. ✅ Vehicle Compatibility — Confirm Your Ram Before Ordering This package fits the following trucks: Ram 1500 Crew Cab — 5th Generation New Body — 2019, 2020, 2021, 2022, 2023, 2024, 2025, 2026 Ram 1500 Quad Cab — 5th Generation New Body — 2019, 2020, 2021, 2022, 2023, 2024, 2025, 2026 �� This package does NOT fit: Ram 1500 Classic (2019–2026) — the Classic carries over the older 4th-gen interior and requires a different enclosure. See our Dodge Ram 2002–2018 & Classic Bass Package. Ram 2500 or 3500 (any year) — the Heavy Duty trucks use the older interior architecture regardless of year and are covered under our separate package. Ram 1500 (2002–2018) — pre-5th-gen trucks use a different under-seat configuration. �� How to confirm you have the 5th Gen New Body Ram 1500: The tailgate or door jamb sticker reads “Ram 1500” — no “Classic” designation The interior is noticeably modern — larger available infotainment screen options (up to 12″), updated dash design, and a wider center console Under the rear seat, the space is flat and open all the way across — no carpeted side storage bins or wells on either side The rear seat bottom cushion lifts or folds as a single wide unit, not as two separate side sections Not sure? Contact our team with your VIN and we’ll confirm the right package for your exact truck before you order. What’s Included ✔ Vehicle-specific under-seat dual 10″ enclosure — engineered for the 5th Gen Ram 1500 new body interior (2019–2026) ✔ Alpine S2-W12D4  12″  subwoofers (1 pair) ✔ Memphis Car Audio PRX1000.1v2 — 1,000 watt monoblock amplifier (1-ohm stable) ✔ Memphis Car Audio 4GKIT — complete 4-gauge amplifier wiring kit ✔ All supplemental hardware and parts needed for a complete professional installation Enclosure: Vehicle-Specific Under-Seat Dual 10″ Subwoofer Box — 5th Gen Ram 1500 New Body (2019–2026) The 5th Generation Ram 1500’s redesigned interior opened up a wider, flatter under-seat cavity — and this vehicle-specific dual 10″ enclosure is engineered to fill it perfectly. Unlike the 4th Gen / Classic trucks that use an up-firing orientation, the 5th Gen enclosure uses a down-firing driver configuration, pushing bass energy toward the floor and using the truck’s interior as a loading surface for maximum low-frequency efficiency. With 1.75 cubic feet of total sealed air space — a significant volume advantage over many under-seat enclosures — both subwoofer options in this package have the room they need to breathe and perform at their best.

This dual 12″ package from Breakers Stereo is one of the strongest available for the 5th Generation Ram 1500 new body. The vehicle-specific down-firing enclosure provides 1.75 cubic feet of sealed air space — a generous volume for under-seat fitment — the Alpine S2-w12d4  subwoofers deliver excellent performance in that alignment. Powered by the Memphis PRX1000.1v2, this is a complete, professionally matched system built specifically for this truck. How do I know if my 2019 Ram 1500 is the new body or the Classic? Look for the word “Classic” on your truck’s tailgate, door jamb sticker, or owner’s manual. If it says “Ram 1500 Classic” — that’s the carryover 4th-gen body style, which requires our separate 2002–2018 & Classic package. If it simply says “Ram 1500” with no Classic designation, and the interior has a modern dash with larger infotainment screen options and a flat, open under-seat area — that’s the 5th Gen new body, and this is the right package. Still unsure? Give us your VIN and we’ll confirm. ALSO if you have cup holders in the middle of the rear seat then it’s more than likely the “Classic” Does the rear seat still fold after the enclosure is installed? Yes. The vehicle-specific enclosure is designed to fit under the rear seat without interfering with seat fold function. No modifications are required for installation in the 5th Gen Ram 1500 Crew Cab or Quad Cab new body trucks. Does this fit a 2022 or 2024 Ram 1500 Crew Cab? Yes — as long as it is the new body 5th Gen Ram 1500, not the Classic. The 5th Generation Ram 1500 maintained the same interior architecture from 2019 through 2026, so this enclosure and all components are confirmed for all new-body model years in that range. Will this work with the Ram 1500’s factory Uconnect or Harman Kardon audio system? The Memphis PRX1000.1v2 can accept RCA signal from an aftermarket head unit or speaker-level signal via a line output converter. The 5th Gen Ram 1500’s factory Uconnect and optional Harman Kardon system use amplified, processed output that may benefit from a DSP or LOC for optimal signal quality. Our installation team handles this integration correctly. Ask us about the right interface method for your specific Ram trim level before ordering.
