Recoil RL680.1 Review: Pocket-Size Mono Amp Listed at 1, 2 and 4 Ohm
The Recoil RL680.1 is a compact Class D mono amplifier from Recoil's L-3 series, listed at 680 W at 1 ohm, 500 W at 2 ohm and 260 W at 4 ohm (14.4 V). Our listing and Recoil's main site give no label for those figures, but Recoil's US store calls the 1 ohm figure RMS. The Indian MRP is ₹18,000, the lower of the two L3 mono amplifiers we list. It suits a subwoofer system where space is tight, and it is the better documented of the two. The full listing is on our product page for the RL680.1.
Key takeaways
Output is listed at 1, 2 and 4 ohm: 680 W, 500 W and 260 W (14.4 V), with no label on our listing or Recoil's main site.
Recoil's US store calls the 680 W at 1 ohm RMS but does not label the other two, so we do not call any figure RMS ourselves.
The body is 105 x 125 x 51 mm, with a 50 to 300 Hz low-pass filter, a 10 to 35 Hz subsonic filter, 0 to 12 dB bass boost and a bass remote.
We found no owner or reviewer write-ups, and Recoil's pages show no reviews.

The figures come from our store listing and agree with Recoil's own RL680.1 page, which marks high-level input sensitivity as N/A and gives no weight. Recoil's US store page repeats the output figures with different labelling.
Three loads, one label
Output falls as the load impedance rises, so the load your subwoofers present is the first thing to settle.
The labelling is less tidy. Our listing and Recoil's main site give the figures at 14.4 V with no RMS, peak or max label. The US store says 680W RMS at 1 ohm and describes the amplifier as scaling down to 500W at 2 ohm and 260W at 4 ohm, with no test voltage. We attribute the RMS label to the US store alone, and none of the pages we read labels the 2 ohm and 4 ohm figures, so we do not call them RMS. Leave headroom when you size subwoofers.
Size, power supply and heat
At 105 x 125 x 51 mm it is small enough for under a seat or inside a compact subwoofer box, which is how Recoil's US page, in promotional wording, describes it. The listing gives a 40 A fuse rating, a 9 to 16 V operating range, 690 mA idle current and thermal, voltage, speaker and DC protection. It gives no cable gauge, so take that from Recoil's documentation.
Class D runs cooler than Class AB but still sheds heat. A closed boot or a carpeted gap under a seat gets very hot in an Indian summer, so leave air around the amplifier. At idle in traffic with the AC running, voltage can sit below the 14.4 V the figures are quoted at, and output falls with it.
Matching subwoofers to 1, 2 and 4 ohm loads
A single 4 ohm subwoofer sees the listed 260 W. Two identical 4 ohm subwoofers in parallel make a 2 ohm load, where the amplifier is listed at 500 W, so about 250 W each if they share equally. Two 2 ohm subwoofers in parallel, or a dual 2 ohm subwoofer with both coils in parallel, make 1 ohm and the listed 680 W. Check each subwoofer's own labelled RMS rating against its share. Recoil L3 options in our store include the single 4 ohm LW8S4 and LW12S4.
The listing gives no minimum load. The 1 ohm figure suggests that load is supported, but confirm it in Recoil's documentation before wiring below 2 ohm. The 50 to 300 Hz low-pass filter keeps the subwoofer to bass, and the 10 to 35 Hz subsonic filter keeps very low rumble out of a ported box.
What owners and reviewers say about the Recoil RL680.1
When we checked in October 2026, we found no owner or reviewer write-ups we could read for the RL680.1. Recoil's main-site page shows Reviews (0) and its US store page shows none, so there are no manufacturer-page reviews to quote, and both pages are promotional. If you already run one, we would like to hear how it behaves.
Compared with the RL1600.1 and ATC500.1
The Recoil RL1600.1 (₹27,000 MRP) is the other L3 mono amplifier we list. Its title says 1500 W at 1 ohm, but the figure has no label, there is nothing at 2 or 4 ohm and no filter, fuse or size information, so the RL680.1 is easier to plan around and costs ₹9,000 less.
The Recoil ATC500.1 (₹25,000 MRP) lists RMS 520 W at 2 ohm and 300 W at 4 ohm, a 1,000 W maximum and a 2 ohm minimum load. On paper its labelled RMS figures are 20 W and 40 W above the RL680.1's 500 W and 260 W, for ₹7,000 more at MRP. The RL680.1 lists a 1 ohm output that the ATC500.1 listing does not, while the ATC500.1 is listed as designed to mount directly in a subwoofer box.
Who should buy it, and who shouldn't
Buy the RL680.1 if you want a small mono amplifier for one or two subwoofers, you want output stated at 1, 2 and 4 ohm, and the filters and bass remote suit how you will tune it. Our guide to the need for an amplifier in car sound systems covers the basics.
Look elsewhere if you want RMS and maximum power stated separately, which the ATC500.1 does, or you need more than one channel. The Recoil RL880.4 and Recoil RL680.4 are four-channel amplifiers from the same series, and the Recoil RL1100.5 adds a fifth channel.
Installation notes for Indian cars
Most factory head units have no RCA outputs. The listing gives a low-level input sensitivity of 220 mV to 12 V and Recoil's main-site page marks high-level sensitivity N/A, so plan on RCA signals from an aftermarket head unit, a processor or a line output converter such as the Recoil RLOC46-LC.
Keep the RCA cables away from the power cable, and use the clip indication, listed at 1%, as a guide when setting gain. VA3 Car Studio offers professional installation in Ghaziabad and builds custom subwoofer enclosures to the volume your subwoofer maker publishes.
Recoil RL680.1 price in India and where to buy
The RL680.1 carries an MRP of ₹18,000. VA3 Car Studio often sells below MRP, so check the current offer on the RL680.1 product page. Our listing describes it as a genuine Recoil product and says Recoil's manufacturer warranty applies where Recoil offers one. Recoil's warranty page is a general statement, headed as a speaker warranty, so confirm the India terms with the maker before you order.
The bottom line
The RL680.1 is the better documented of the two L3 mono amplifiers we list: output at three loads, filters, a fuse rating and a body small enough for tight spaces, for ₹18,000 MRP. Its weak spot is labelling: of the pages we read, only Recoil's US store calls any figure RMS, and only the 1 ohm one. Pair it with subwoofers whose own RMS ratings are labelled, and confirm the minimum load before you wire to 1 ohm.
Recoil RL680.1 FAQ
What power does the Recoil RL680.1 deliver?
Our listing gives 680 W at 1 ohm, 500 W at 2 ohm and 260 W at 4 ohm (14.4 V), without a label. Recoil's US store calls the 680 W at 1 ohm RMS; we do not call the other two figures RMS.
Can the RL680.1 run a 1 ohm load?
Its listing gives 680 W at 1 ohm, which suggests that load is supported, but no page we read states a minimum load. Confirm it in Recoil's documentation before wiring below 2 ohm.
Does the RL680.1 come with a bass remote?
Yes. Our listing and Recoil's main-site page both list a bass remote as included.
