Slide a 10-inch powered sub under the driver seat. The built-in amp means zero extra boxes in the cargo area.

Rear-Seat Entertainment, No Tablet Needed
Android headrest monitors stream 4K video over WiFi. Pair two screens via HDMI so both passengers watch the same movie.
Parking Radar That Beeps Before You Bump
PDC sensors trigger progressive audio warnings as obstacles close in. The 1080P camera keeps recording while the radar measures distance.

What Seventour Gear Actually Does in Your Car
Drop a 10-Inch Sub Under Your Seat and Keep Every Inch of Trunk Space
A 2.5-mile daily commuter picked the ST-1000 enclosed sub at $94. The carbon-fiber-reinforced enclosure cleared the seat rail by half an inch in a Civic sedan. Low-pass filtering adjusts between 50 Hz and 150 Hz, so kick drums punch without muddying vocal frequencies. Bass boost tops out at 12 dB at 45 Hz.
- Built-in amplifier powers the 10-inch driver directly. No second box, no extra wiring run to the trunk.
- Adjustable input sensitivity accepts both RCA pre-outs and high-level speaker wires from factory head units.
- Thermal protection circuitry shuts down the amp before heat damages the voice coil during a two-hour highway cruise.
Watch Six Camera Angles on One Screen While You Park a Trailer
A truck owner wired six 1080P cameras to the 10.33-inch IPS touch display in a Saturday morning. Front bumper, tailgate, both mirrors, cabin, and trailer hitch each occupy a tile on the split-screen view. DVR loop recording saves the last 48 hours to a micro SD card.
- IP67-rated camera housings survive daily car washes and winter salt spray without fogging the lens.
- 170-degree wide-angle lenses eliminate the blind corridor between the bumper and the first parking sensor.
- Android 11 head unit doubles as a CarPlay and Android Auto receiver, keeping factory steering-wheel controls active.
Stream Netflix on a 15-Inch Screen From the Back Seat
Two kids logged into separate Disney+ profiles on a pair of linked 12.4-inch headrest monitors during a six-hour highway drive. Android 13 runs the streaming apps natively over a phone hotspot at 5 GHz. HDMI input turned the same monitor into a PS5 display at a rest-stop parking lot.
- 4GB RAM and 64GB storage load YouTube, Netflix, and Disney+ without buffering stalls on a stable hotspot.
- MyCar Link app mirrors iOS and Android phones wirelessly. No cable dangling across the center console.
- HDMI output chains two monitors together so passengers in both seats watch the same 4K video in sync.
Tune Every Frequency From Your Phone Before the Engine Starts
A first-time DSP owner connected the P48E to a factory Honda head unit using high-level speaker inputs. The PC software mapped 31 EQ bands across the 20 Hz to 20 kHz range in under ten minutes. The TDA7850 chip pushed 4x50W peak through eight output channels with THD under 0.01%.
- 31-band graphic equalizer separates sub-bass, midbass, midrange, and treble into individually tunable slices.
- Bluetooth 5.0 streams music directly from a phone, bypassing the factory radio when you want a cleaner signal path.
- Wired knob controller mounts to the dash for one-touch preset switching without unlocking a phone mid-drive.
About Seventour
Seventour started as a car audio supplier and grew into a five-category electronics brand sold through Amazon. The product line now covers under-seat subwoofers, multi-channel backup camera systems, 4K Android headrest monitors, DSP signal processors, and coaxial car speakers.
Fifteen active products span $49.88 to $792.99. A Ford F-150 owner replaced both factory 6x9 speakers with a Seventour 180W RMS direct-fit pair for $99 and gained cleaner midrange across the cab without rewiring a single harness. That install took forty minutes.
Every unit ships with mounting hardware, wiring, and a customer support channel that replies within 12 hours.

This is a very good value for the money, and I was shocked by the installation kit that included everything I needed. The bass is punchy for the size. I drive a Honda Accord and this fits cleanly under the driver seat with zero rattle. The LED ring adds a nice visual touch at night. I've had it for two months now with no issues.
This little sub packs a huge punch if you have limited space. I installed this on my 2015 Jeep Rubicon and it fills the cabin with deep bass on highway drives. The RGB LED is a bonus. Seventour reached out proactively when I had a minor issue and sent a replacement within a week. Customer service is top-notch for this price range.
Hilariously massive roll surround but insane excursion. Double-stacked magnet. This thing handles its rated 600W RMS without breaking a sweat. I paired it with a Taramps amp in a sealed 0.8 cu ft box and the low end is tight and clean. Build quality surprised me at this price point. The dual 4-ohm coils give you flexible wiring options.
I needed cameras for my RV and this system covered every angle I cared about. Five cameras, one clean touch screen on the dash. The night vision is surprisingly clear on unlit campground roads. I contacted support about a cable length question and they responded within hours. For under $260, this replaced a $600 quote from a local installer.
Great product, sound is awesome. I have it in my Wagoneer and you can hear one TV in the whole car. My kids use it for Netflix on long drives. The 14-inch screen is bright, crisp, and the touch response is snappy. Android 13 runs smoothly. AirPlay worked instantly with my wife's iPhone. One of the best upgrades I've done to this vehicle.
Excellent sounding speakers. I'm honestly impressed with the sound quality for the price. Drop-in fit for my 2019 F-150. The included adapters and harness meant zero cutting or splicing. Took me about 30 minutes per door. Bass response from the 6x9 coaxial design rivals speakers at twice the cost. Vocals sound clear at highway speeds.
Good product and the best customer support I came across. Had a little issue with the product and they resolved it quickly. Six cameras give me complete coverage around my truck. The Android system with CarPlay is a nice bonus. Touch screen is responsive and clear. I use it daily for backing up a 22-foot trailer.
Excellent value for the money. Once you get in and your EQ all dialed in, this thing bumps. Very crisp and clear bass. Easy install in my Ram 1500. I set the LPF to about 80 Hz and bass boost to 6 dB and it fills the cab perfectly. Great addition to the factory speakers without being overwhelming for daily listening.

What You'll Get
Unbox and Install
Unbox the sub, bolt the bracket under the driver seat, and connect two wires to the fuse box. Bass fills the cabin before dinner.
Dial Your Sound
Dial the low-pass filter to 80 Hz for music, 120 Hz for podcasts. Set bass boost at 6 dB. Your commute playlist sounds different on every road surface.
Build Muscle Memory
Muscle memory kicks in. You tap the phone app to switch EQ presets between highway and city driving without looking at the screen.
Warranty Still Active
The 6-month replacement window closes, but the 12-month repair warranty still covers any voice-coil or amp-board failure at no charge.
Problems Seventour Solves
Trunk is full. Where does a subwoofer go?
Traditional subs steal 1-2 cubic feet of cargo space. Seventour's under-seat models measure under 4 inches tall and bolt directly to the seat rail. The trunk stays full without sacrificing low end.
68% of top-10 sub best sellers are now slim under-seat models
Factory speakers went flat, but a full overhaul quotes $1,000+
A shop-installed amplifier, subwoofer, and wiring harness adds up fast. Seventour bundles the amp inside the sub enclosure and accepts factory speaker-level inputs. Total cost: under $95, installed by you.
Backing out with a cracked mirror and blind spots
A single backup camera covers the rear bumper. Seventour's 5-channel system adds left, right, front, and cabin views on one split-screen monitor. PDC radar beeps when an obstacle enters the last three feet.
Two kids fighting over a tablet on a six-hour drive
Tablets run out of battery, slip off mounts, and create arguments over screen control. Seventour headrest monitors bolt to the seat post, run Android 13 independently, and link via HDMI for shared playback.
Last year's budget sub rattled apart by month three
Loose enclosures and missing thermal protection kill cheap subwoofers fast. Seventour seals every enclosure with carbon-fiber-reinforced panels and wires thermal cutoff circuits into the amp board.
Built For You
Daily Commuter
You drive 25 miles each way in a sedan. An under-seat sub at $78 adds low end to your morning playlist without touching cargo space. Install takes one hour.
Safety-Conscious Parent
Bikes and scooters scatter behind the minivan every afternoon. A 5-channel camera system puts four exterior views and one cabin view on a single 10.2-inch screen.
Road-Trip Family
Six hours to the coast, two kids, one tablet. Dual 12.4-inch headrest monitors run separate Disney+ profiles or link via HDMI for the same movie.
Truck Owner Replacing Factory Speakers
Your 2018 F-150 factory speakers crackle above half volume. Seventour's direct-fit 6x9 pair bolts into stock mounting holes. 180W RMS fills the cab.
Not for: Competition-level SPL builders chasing 150+ dB at the dash. Seventour targets daily listening comfort, not trophy scores.
Expert Recommendation
Marcus Delgado
Car Audio Installer & Product Reviewer, 12 Years Experience
Budget under-seat subs have closed the gap on mid-tier brands faster than most installers expected. Three years ago, a sub under $100 meant flimsy enclosures and blown voice coils by summer. The current generation uses sealed carbon-fiber panels and thermal cutoff circuits that handle Arizona parking-lot heat. Seventour's ST-1000 line sits at the front of that shift.
- Start with the ST-1000 enclosed sub if you want bass in 30 minutes. No box building, no amp matching.
- Pair the 6-channel camera system with the PDC sensors for trucks and SUVs. The radar beep catches what mirrors miss at dusk.
- Run the P48E DSP tuning from a laptop first. Map all 31 bands, save three presets, then use the phone app for daily switching.
