Recoil RST11 Review: Active 11-Inch Spare-Tyre Subwoofer With Built-In Amplifier
The Recoil RST11 is an 11-inch active subwoofer that takes the spare-wheel position and carries its own Class D amplifier, so there is no separate amplifier to buy or hide. Our listing rates that amplifier at 200 W RMS and 1000 W peak, and the Indian MRP is ₹50,000, the higher of the two Recoil spare-tyre subwoofer prices we list. It suits a buyer who wants the boot kept clear and prefers one self-contained unit to a sub-and-amplifier pair. One caution up front: Recoil's own page for it gives the same power and performance figures as our listing but no fitment rules, so confirm fitment with the maker before you order. You can see the unit on our RST11 product page.
Key takeaways
The amplifier is built in. Our listing gives 200 W RMS and 1000 W peak; the RMS line is the one to compare.
The listing says a remote sets the crossover point, gain, phase and bass boost, and the harness carries both high-level and RCA inputs.
Recoil's page for the RST11 gives the same power and frequency figures as our listing, but no fitment rules, so confirm size and fitment with the maker before ordering.
We found no owner reviews to summarise.

Every figure above comes from our store listing. Recoil's RST11 page, which is promotional material, prints the same power, response, filter, boost, sensitivity, distortion, signal-to-noise and size figures. Its separate additional-information table gives a weight and a size that look too small for an 11-inch driver, so we have not used that table.
What is built into the RST11
The listing describes a Class D amplifier with over-temperature and over-current protection. Protection circuits are safeguards, not a reason to ignore heat, and a spare-wheel well is an enclosed space, so keep the area around the unit free of luggage.
The remote matters more here than on an under-seat unit, because nobody can reach a knob on something buried under the boot floor. The listing says it adjusts the crossover point, gain, phase and bass boost up to +12 dB, but does not say whether the remote is wired or wireless, and neither does Recoil's page, so confirm that with the maker before you plan where it will sit.
Reading the RST11's 200 W and 1000 W
Our listing title says 1000W. That is the peak rating of the built-in amplifier; its RMS rating is 200 W, and Recoil's page labels the two figures the same way. Peak numbers describe short bursts and say little about everyday output, so compare on RMS. On that line the RST11 matches the Recoil LAS10 at 200 W RMS, sits below the Recoil SW10P at 300 W RMS, and is above the Recoil RLS10 at 150 W RMS and the Recoil SL1708 at 120 W RMS.
What Recoil's own page leaves out
Recoil's PST12 page spells out a removable-post requirement for the spare wheel. Neither Recoil's RST11 page nor our listing gives fitment rules for the RST11, so do not assume the PST12's rules apply, or that they don't. Confirm fitment for your car with the maker before ordering, and check the unit's size against your wheel well.
The size also needs care. Recoil's page gives the 360 mm by 144 mm size in its specification list but a much smaller one in a separate table, so check the dimensions against your wheel well before you pay.
What owners and reviewers say about the Recoil RST11
When we checked in October 2026, Recoil's RST11 page showed no customer reviews, and we found no owner thread, retailer review or published test that we could open and read. Several large retailer and video sites would not load for our research, so this is a gap in what we could verify, not proof that nobody owns one.
We would rather leave this section short than invent a consensus. If you have an RST11 in your car, add a comment below and tell other buyers how it behaves.
RST11 vs PST12 and LAS10
The Recoil PST12 is the passive 12-inch spare-tyre alternative, with a 350 W RMS driver rating and an MRP of ₹34,000, but it needs an amplifier and wiring you supply. Add those before comparing it with the ₹50,000 RST11.
The LAS10 lists the same 200 W RMS built-in amplifier at ₹27,000, but it is a shallow under-seat or compact-space unit, not a spare-wheel one. Between the two, decide by where the unit has to live, not by power.
Who should buy it, and who shouldn't
Buy it if you want a self-contained sub that hides in the spare-wheel position, your car's spare arrangement suits it (confirm fitment with the maker before ordering), and you would rather not choose and mount an amplifier yourself.
Look elsewhere if your car has no spare wheel or carries it elsewhere, in which case an under-seat unit such as the Recoil RLS10 does not depend on the spare. If you want fitment rules confirmed on the maker's own page before paying, the PST12's page publishes them, and the RST11's does not.
Installation notes for Indian cars
Plan the power run first. The listing says the harness carries power, ground, high-level input, remote turn-on and RCA, and neither Recoil's page nor our listing publishes a fuse rating for the RST11, so confirm the correct fuse rating with the maker before you wire it, and keep the fuse close to the battery. Ground to clean bare metal, and route the harness away from the wheel and any sharp edges.
Many factory touchscreen head units have no RCA output, which is where the high-level input helps: it accepts a speaker-level signal. Check that the spare-wheel well stays dry through a monsoon, and practise the quick release once so you can reach the wheel when you need it. VA3 Car Studio in Ghaziabad offers professional installation.
Price and where to buy
The Recoil RST11 has an MRP of ₹50,000 in our listing. VA3 Car Studio often sells below MRP, so the current offer is on the RST11 product page. We list it as a genuine Recoil product. Recoil's warranty page reads as US terms, so confirm India terms with the maker before you buy.
The bottom line
The Recoil RST11 is a self-contained take on the spare-wheel subwoofer: a powered 11-inch sub with a built-in amplifier, a remote and a ready harness. What it lacks is independent confirmation: Recoil's page gives no fitment rules and we found no owner reviews. Confirm fitment with the maker before ordering, and judge it on the 200 W RMS rating, not the 1000 W peak in the title.
Recoil RST11 FAQ
Is the Recoil RST11 a 1000 W subwoofer?
Not in RMS terms. Our listing gives its built-in amplifier as 200 W RMS and 1000 W peak, so the 1000W in the title is the peak figure.
Does the RST11 need a separate amplifier?
No. It has a built-in Class D amplifier, but it still needs power from the car's battery. The listing says the supplied harness carries power, ground, high-level input, remote turn-on and RCA connections.
Can the RST11 connect to a factory head unit?
The listing says the harness includes a high-level input, which takes a speaker-level signal, as well as an RCA input. Whether your car offers a suitable tap depends on the car, so confirm fitment for your car with the maker before ordering.
