Recoil PST12 Review: Passive Spare-Tyre Subwoofer, Wiring and Fitment Limits
The Recoil PST12 is a 12-inch passive subwoofer that sits inside the spare-wheel rim, so you get bass without giving up boot space. Recoil rates it at 350 W RMS and 700 W peak, with dual 4-ohm voice coils that wire to a 2-ohm or an 8-ohm load, and it has no amplifier of its own. Its Indian MRP is ₹34,000. Of the two Recoil spare-tyre subwoofers we list, it is the passive one; the active alternative is the RST11. It suits a buyer who wants a clear boot and doesn't mind choosing a separate amplifier. You can see it on our PST12 product page.
Key takeaways
Passive means no built-in amplifier. Budget for an amplifier, power cable and speaker wire on top of the ₹34,000 MRP.
The 700 W in our listing title is a peak figure. The rating to match an amplifier against is 350 W RMS.
Recoil says it fits only vehicles that store the spare inside the vehicle on a removable post, not a welded one.
We found no owner reviews to summarise, so this post sticks to what Recoil and our listing publish.

Figures come from Recoil's PST12 page and Recoil's US store page, both promotional material, plus our own listing. Recoil doesn't say which of the two profile measurements is the diameter, and the PST12 page's additional-information table prints a different 16 x 15.8 x 7.1 in without saying what it measures, so we have used the US page's profile.
Inside the PST12: driver and enclosure
The driver is a 12-inch fibreglass IMPP cone on a butyl rubber surround, held in a cast-aluminium housing shaped to drop into a spare wheel. Recoil says the spare tyre is turned upside down for installation and that the unit mounts inside the rim.
A quick-release feature gives access to the wheel. Recoil's published response is 52 Hz to 150 Hz. That low end sits above the deepest notes in some electronic music, so judge it against what you actually listen to.
Wiring the PST12: 2 ohm or 8 ohm?
Two 4-ohm voice coils give you a choice. Wired in parallel they present 2 ohms; wired in series they present 8 ohms. Many car amplifiers list their ratings at 4 ohm and 2 ohm only, so 2 ohms is usually the practical route unless an amplifier's page lists an 8-ohm rating.
The number to match is RMS. Our listing title shows 700 W, the peak figure, and an amplifier sold on a max number can be a poor match. Look for a labelled RMS output at your chosen load in the region of 350 W. Recoil's ATC500.1, for instance, lists RMS figures at 2 ohm and 4 ohm, which makes that comparison easy. If you are starting from a factory system, our guide on whether you need an amplifier covers the basics.
What owners and reviewers say about the Recoil PST12
When we checked in October 2026, Recoil's own PST12 page showed no customer reviews, and its US store page showed no ratings either. Beyond those promotional pages 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.
So there is no verified consensus to report, and we would rather say that than guess. If you have fitted a PST12, tell us how it went in the comments; it will help the next buyer.
PST12 vs the active Recoil RST11
The Recoil RST11 is the second Recoil spare-tyre subwoofer we list, and the choice between the two is mostly passive versus active. The RST11 is an 11-inch unit with a built-in Class D amplifier, listed at 200 W RMS and 1000 W peak, and its MRP is ₹50,000.
The two sets of numbers describe different things. The PST12's 350 W RMS and 700 W peak are what the driver can handle; the RST11's 200 W RMS and 1000 W peak are what its amplifier is listed to deliver. Once you add an amplifier, wiring and fitting to the PST12, compare complete system costs rather than the price tags alone.
Who should buy it, and who shouldn't
Buy it if your car keeps its spare inside the boot on a removable post, you want the boot floor left free, and you are happy to choose an amplifier yourself. It also suits a staged build: a modest amplifier now, a stronger one later, up to the 350 W RMS rating.
Look elsewhere if your car has no spare wheel, carries it on the tailgate or underneath, or uses a welded post: an under-seat unit such as the Recoil RLS10 does not depend on the spare. If you want everything in one box, the RST11 puts the amplifier inside the unit.
Installation notes for Indian cars
Start with the spare. Open the boot floor and check that the centre post unscrews rather than being welded, and that the car carries a wheel at all; if yours has only a tyre-repair kit, there is nothing to mount the PST12 in. Confirm fitment for your car with the maker before ordering.
Run the speaker wire from the boot to the amplifier, and the amplifier's power cable to the battery through a fuse close to the battery, keeping both clear of the wheel well where they could chafe. Check the well stays dry through a monsoon, and practise the quick release once so you can reach the wheel on the day of a puncture. VA3 Car Studio in Ghaziabad offers professional installation.
Price and where to buy
The Recoil PST12 carries an MRP of ₹34,000 in our listing. VA3 Car Studio often sells below MRP, so check the current offer on the PST12 product page. We list it as a genuine Recoil product. For warranty, Recoil's published warranty page describes one year from the date of purchase under US terms, so confirm India terms with the maker before you buy.
The bottom line
The Recoil PST12 is a direct way to add a 12-inch driver without a box in the boot, as long as your spare sits inside the car on a removable post. Its ratings are clear once you read the RMS line, and the real cost is the amplifier and wiring you add. With no owner reviews to lean on, confirm fitment first, then size the amplifier to 350 W RMS, not to the 700 W headline.
Recoil PST12 FAQ
Does the Recoil PST12 need an amplifier?
Yes. It is a passive subwoofer with no built-in amplifier, so it needs an external amplifier matched to its 350 W RMS rating at the 2-ohm or 8-ohm load you wire it for.
Is the PST12 really a 700 W subwoofer?
Not in RMS terms. Recoil gives 350 W RMS and 700 W peak, and the 700 W in our listing title is the peak figure. Match your amplifier to the RMS rating.
Will the PST12 fit any car with a spare wheel?
Not necessarily. Recoil says it is only for vehicles that store the spare inside the vehicle and have a removable spare-wheel post, not a welded one. Confirm fitment for your car with the maker before ordering.
