Skar 2400 Watt Subwoofer Review
If you’re chasing that “windows buzz, rearview rattles” moment, this bundle makes it easy. The SDR-2X12D4 ported enclosure arrives pre-loaded with two SDR 12-inch D4 subs and is pre-wired to a 1-ohm final load at the terminal cup—pairing cleanly with the included RP-1200.1D Class-D monoblock. Translation: you drop the box in, mount the amp, run the included 4-gauge OFC kit with an ANL fuse, set gains correctly, and you’re in business.
On the road, it strikes a nice balance between party-loud and musically usable. That long kerf-style port and ~32 Hz tuning lend real depth without turning everything to mush, so kick drums stay tight and 808s feel thick rather than flabby. It’s happiest in sedans, hatches, and SUVs where the cabin can load the bass—monster, open cabins may want more power or additional electrical support (big three, AGM/aux battery) to keep voltage healthy.

At the heart of this package are two 12-inch Skar Audio SDR series subwoofers housed in a custom-loaded enclosure, paired with an amplifier engineered to push up to 2,400 watts. Here’s what makes this setup stand out:
All-in-one bundle that actually matches
You’re not guessing at box volume, coil wiring, or amp pairing—the enclosure, subs, amp, and wiring are designed to work together. That means fewer trips back to the store and way less forum-diving. Unbox, install, tune, and go shake some mirrors.
Pre-loaded dual 12s with smart porting
The enclosure arrives loaded and pre-wired, so you skip the messy part and get straight to bass. Its long, flared port is tuned to deliver real low-end weight without turning everything to mud. Translation: 808s hit deep, kick drums stay punchy, and your playlists feel bigger.
Matched monoblock power (the right kind)
The included Class-D amp is built for sub duty and plays nicely with the box’s final 1-ohm load. It wakes up the drivers without getting sloppy, and it runs cooler and cleaner than the “mystery power” amps you find in random kits. Set gains correctly and it’ll slam for years.
Real 4-gauge OFC wiring kit
Copper that’s actually copper—no flaky CCA surprises here. The kit includes the big stuff (power, ground, fuse holder) plus signal cables and remote wire, so you’re not waiting on a second order. Good wire = less voltage drop = happier amp.
Beginner-friendly install, pro-worthy results
If you can route a power cable through the firewall and find a solid ground, you can install this. The enclosure is pre-wired to the right impedance, so the “do I wire series or parallel?” panic never happens. Take your time with the routing and you’ll get a clean, rattle-free setup.
Tuning that favors music, not just noise
It’s easy to make bass loud; it’s harder to make it enjoyable. This box is voiced for both depth and definition, so you get cinema boom and musical groove. A quick tweak of subsonic, low-pass, and gain, and you’ll hear the difference between “boom car” and “built right.”
Factory-radio friendly (with a simple add-on)
Running a stock head unit? A decent line-out converter will feed the amp just fine. You keep steering-wheel controls and factory features, and still get the bass you wanted. It’s the best of both worlds when you don’t want to redo your whole dash.
Built to live in a trunk
The enclosure uses thick MDF and a reinforced baffle to survive bumps, potholes, and weekly grocery runs. Corners and carpet hold up to sliding cargo better than bare wood boxes. It’s heavy because it’s solid—and that solidity keeps unwanted rattles at bay.
Legit upgrade path
Start with the bundle and enjoy it; when the itch hits, you can add sound deadening, upgrade your “big three” wires under the hood, or step up to more amplifier if you ever want more output. The system is a foundation you can build on, not a dead end.
Daily-driver reliability tips baked in
Because it’s a matched kit, the gains and filters are easy to set conservatively. Keep the fuse near the battery, scrape paint for your ground, and mount the amp where it gets airflow. Do those three things and you’ll spend your time listening—not troubleshooting.
Sound Quality Deep Dive
What do the fans say about the sound? The vast majority of users seem genuinely impressed. The consensus highlights that the package delivers bass that doesn’t just fill a room — it fills an entire car, shaking everything within.
Multiple users mention that the bass shakes their entire vehicle, with one enthusiast reporting it even rattles their rearview mirror. That’s serious low-end power, the kind that can turn casual listeners into bassheads.
Clarity and punch are also commonly praised. Listeners note that the bass doesn’t just thump — it hits hard while maintaining precision. This balance makes music sound richer and more immersive whether you’re blasting hip-hop, EDM, or classic rock.
That said, some owners mention the amplifier can be a mixed bag. While many are thrilled with its strength and how it amplifies the sound, a few users report issues with the amp functionality. This might depend on individual units or installation, but the vast majority of feedback is positive.
One subtle point worth noting is how this system’s intensity might not be for everyone. If you love that full-car vibration and deep rumble, this package will satisfy those cravings. But if you’re after subtle background bass, it might feel a little over the top.
Who Is It For?
The Skar12′ SDR Subwoofer is tailor-made for bass lovers who want to upgrade their car audio experience with minimal fuss. It’s perfect for beginners because of its all-in-one design and for anyone who craves a powerhouse bass system without spending a fortune.
If you’re someone who enjoys feeling bass as much as hearing it — the tactile thump that turns heads and shakes windows — this package will likely satisfy. It’s also a great choice for hobbyists who want a solid, reliable system that works right out of the box and is easy to install.
However, if your audio preference leans towards subtlety or if you’re worried about potential amplifier hiccups, you may want to shop around or prepare for some tweaking during setup.
Final Thoughts
Skar 2,400 Subwoofer Bass Package is a compelling option for anyone looking to inject serious bass power into their vehicle without drowning in the complexities of custom installations or overspending. It offers a potent combination of solid build quality, impressive volume, and punchy sound that even bass purists will appreciate.
Yes, it has its quirks — particularly around amplifier consistency — but most owners clearly think this setup is a crowd-pleaser. Beginners get a no-fuss package to kickstart their car audio upgrade, and seasoned bass fans get a robust system that genuinely shakes the ride.

FAQ
Q. Is the “2400W” number real?
A. It’s the enclosure’s peak rating. The included amp is about 1200 W RMS at 1 Ω, which is the meaningful everyday power number.
Q. Do I need anything else to install it?
A. You get a full 4-ga OFC kit, but you’ll still need basic tools, a clean chassis ground, and a path through the firewall for power. A line-out converter may be required if you’re using a factory head unit without RCA outs.
Q. Will it fit my car?
A. The box is big and heavy. Measure your trunk/hatch opening and depth before you buy, and be sure you can still access your spare tire if needed.
Q. Will this drain my battery or dim my lights?
A. At spirited volumes it can. Healthy wiring, solid grounds, and good battery condition help. If dimming persists, consider a “big three” upgrade or higher-capacity battery.
Q. How do I set gains so I don’t fry anything?
A. Start with the head unit at ~75% of max clean volume, turn the amp gain down, then raise it slowly until the bass is strong without distortion. Set the subsonic filter just below the enclosure tuning (~28–30 Hz) and low-pass around 80–100 Hz to taste.
Q. Is it just loud, or does it sound good?
A. Both—when tuned right. The enclosure’s port tuning and the SDR drivers give real output down low, but they also stay composed enough for rock and pop where bass lines need definition.
Q. Can I add more subs later?
A. Not to this exact pre-wired box. If you want to expand, you’d look at different enclosures/amps designed for multi-sub setups (and plan electrical accordingly).
Q. Will it work with a factory radio?
A. Yes, with a quality line-out converter feeding the amp. Many installs do exactly that—just make sure you tap a full-range signal.
Q. How “beginner-friendly” is it really?
A. Much easier than sourcing parts separately, but it’s still a real car-audio install. If running power wire through the firewall sounds daunting, a local shop can finish the job quickly.
Q. What music does it suit best?
A. Anything with low-end energy—hip-hop, EDM, trap, pop, metal. It adds weight to quieter genres too, but this package is built to move air when asked.
