Recoil RLS10 Review: 150 W RMS Under-Seat Subwoofer Only 75 mm Tall
The Recoil RLS10 is a powered under-seat subwoofer with a 10-inch driver in a case that stands only about 75 mm (2.95 inches) tall, driven by a built-in Class D mono amplifier rated at 150 W RMS. Its Indian MRP is ₹20,000, the lowest of the five powered Recoil subwoofers we list. It takes RCA or speaker-level inputs and comes with a wired bass remote. It suits a buyer who wants to add bass to a car without touching the boot, and who accepts that Recoil publishes only the RMS figure for its amplifier. Details are on our RLS10 product page.
Key takeaways
150 W RMS from a built-in Class D mono amplifier is the only power rating Recoil's page and our listing publish. There is no peak rating to confuse it with.
The case is about 351 x 264 x 75 mm (13.8 x 10.4 x 2.95 in), so the height is the number to check against the gap under your seat.
Recoil lists auto signal-sensing turn-on, RCA and high-level inputs, a wired bass remote, and adjustable low-pass filter, bass boost and phase.
We found no owner reviews to summarise.

A 10-inch driver in a 75 mm case
A 10-inch subwoofer is usually a box. The RLS10 is a flat case with a footprint of roughly 351 x 264 mm, so it is wide rather than tall. Recoil's own copy calls it suited to larger vehicles and says it fits under most vehicle seats, but it names no car, and under-seat clearance varies a great deal between models.
So the check is simple and cheap: measure the gap under the seat at its lowest setting and compare it with 75 mm, adding room for the brackets and the cable that leaves the case. Confirm fitment for your car with the maker before ordering if the margin is thin.
Auto turn-on, inputs and the wired remote
Recoil says the RLS10 turns on when it detects an audio signal, with no separate remote wire needed in auto mode. That helps with a factory head unit that has no remote turn-on lead. The unit also takes both RCA and speaker-level inputs, and the in-box harness is a high-level one, so a stock radio with only speaker outputs can usually feed it.
A wired bass remote is included, and the low-pass filter, bass boost and phase are all adjustable. Recoil does not publish the ranges, so you will set these by ear, and the listed contents include mounting brackets, Velcro, the harness and hardware but no power and ground cable kit.
What owners and reviewers say about the Recoil RLS10
When we checked in October 2026, Recoil's RLS10 page showed no customer reviews. We did not find an owner thread, retailer review or published test that we could open and read, and several large retailer and video sites would not load for our research. That is a gap in what we can verify, not evidence that nobody owns one.
We would rather say that plainly than make up a consensus. If you run an RLS10, leave a comment and tell other buyers how it fits and sounds in your car.
RLS10 vs SL1708 and LAS10
The Recoil SL1708 is the closest like-for-like on thickness: it is listed at 80 mm, so the two are about the same height. The SL1708 pairs an 8-inch driver with a round housing of 245 mm diameter and lists 120 W RMS and 500 W peak at ₹27,000; the RLS10 offers the bigger driver and the bigger footprint at 150 W RMS and ₹20,000.
The Recoil LAS10 lists 200 W RMS at ₹27,000, but gives no dimensions at all. If you want the higher RMS rating and can confirm the space, it is worth a look. If the height must be known before you order, the RLS10 is the safer pick.
Who should buy it, and who shouldn't
Buy it if you drive a car with room under the seat, want the lowest-priced powered Recoil subwoofer we list, and are happy with a single published power figure. Auto turn-on and RCA plus speaker-level inputs make it flexible with different head units.
Look elsewhere if you need peak power, impedance or filter ranges on paper, want a power cable kit in the box, or have shallow seat clearance that you cannot confirm. The SL1708 lists a wiring kit and more of its filter ranges. If you have boot space to spare and want more RMS, the boxed Recoil SW10P is rated at 300 W RMS.
Installation notes for Indian cars
Treat the Velcro as a helper, not the anchor: use the brackets too, so the case stays put over potholes and speed breakers. Keep it clear of the seat rails and of any wiring running under the seat, and move the seat through its full travel before you close up. A powered case needs air around it, so avoid wrapping it in carpet.
Since no power cable kit is listed, buy one. Neither Recoil's page nor our listing gives a fuse rating, so confirm the correct fuse rating with the maker before you wire it. Route the cable along the floor, away from the seat mechanism. VA3 Car Studio in Ghaziabad offers professional installation.
Price and where to buy
The Recoil RLS10 carries an MRP of ₹20,000 in our listing. VA3 Car Studio often sells below MRP, so check the current offer on the RLS10 product page. We list it as a genuine Recoil product.
The bottom line
The Recoil RLS10 is the lowest-priced powered Recoil subwoofer we list, and a sensible one if your seat clearance allows a 75 mm case. Its published detail is thin, with one power figure, no peak rating and no owner reviews, so measure the gap, plan for a separate power kit, and treat the 150 W RMS as the number that counts.
Recoil RLS10 FAQ
Does the Recoil RLS10 turn on automatically?
Recoil says it has auto signal sensing, so it switches on when it detects an audio signal from the stereo, with no separate remote wire needed in auto mode. Confirm fitment for your car with the maker before ordering.
How tall is the RLS10?
Recoil lists the case at about 75 mm (2.95 inches) high and about 351 x 264 x 75 mm (13.8 x 10.4 x 2.95 in) overall. Measure the clearance under your seat before ordering.
Is the RLS10 rated in RMS or peak watts?
RMS. Recoil gives 150 W RMS for the built-in Class D mono amplifier, and neither Recoil's page nor our listing publishes a peak figure for it.
