Recoil RL680.4 Review: What the 680 W Adds Up To in a Pocket-Size Amp
The Recoil RL680.4 is a pocket-size full-range Class D four-channel amplifier from Recoil's L-3 series, listed at 95 W x 4 at 4 ohm and 170 W x 4 at 2 ohm (14.4 V), with 250 W x 2 bridged at 4 ohm. Neither our listing nor Recoil's main-site page labels those figures RMS, peak or max, so we quote them as listed. The Indian MRP is ₹17,000, the lowest of the four-channel L3 amplifiers we list. The full listing is on our product page for the RL680.4.
Key takeaways
Listed output is 95 W x 4 at 4 ohm, 170 W x 4 at 2 ohm and 250 W x 2 bridged at 4 ohm (14.4 V), with no power label on our listing or Recoil's main-site page.
The 680 W in the name matches four channels at 170 W, the 2 ohm total. At 4 ohm the four channels add up to 380 W.
The listing gives a 35 A fuse rating, a 9 to 16 V operating range and 750 mA idle current, but only a low-level input range, so plan on RCA signals.
One dimension is listed as both 108 mm and 3.97 in, which disagree. We found no owner or reviewer write-ups.

The figures come from our store listing and agree with Recoil's own RL680.4 page, which is promotional copy. That page marks the 1 ohm output, the bridged 2 ohm output, high-level input, bass boost, subsonic filter and bass remote as N/A.
What the 680 W in the name adds up to
Four channels at 170 W make 680 W, so the name fits the 2 ohm output across all channels. Our listing says only that the amplifier is rated at 680 W, and Recoil's main-site title gives 680 Watts with no label, so we do not call any figure here RMS.
Most door speakers are 4 ohm, where the listing gives 95 W per channel, 380 W in total. Recoil's page marks a 1 ohm output and a bridged 2 ohm output as N/A, so the lowest loads listed are 2 ohm per channel and 4 ohm bridged.
Matching it to door speakers
With 95 W per channel at 4 ohm, the usual jobs are a front pair and a rear pair of door speakers. Because the 95 W carries no label, we cannot call it RMS, so compare it with each speaker's own labelled RMS rating and keep the gain low until you have checked for clipping.
As an example, our listing for the Recoil RLM65 6.5 inch component set gives 80 W RMS and 160 W peak for the pair, or 40 W RMS and 80 W max per side. Next to 95 W per channel, that gap is why the speaker's labelled RMS rating, not the amplifier's headline figure, should guide your gain.
Bridging, and why a subwoofer wants another amplifier
Bridging joins two channels into one stronger output, and the listing gives 250 W x 2 that way at 4 ohm. Neither our listing nor Recoil's page says how the channels pair up, so confirm that in Recoil's documentation before planning a layout that bridges one pair for a subwoofer.
A subwoofer usually wants bass controls. Recoil's page marks this model's bass boost, subsonic filter and bass remote as N/A, while the Recoil RL680.1 mono amplifier lists all three.
Inputs: low level only on paper
The listing gives a low-level input range of 220 mV to 12 V and lists no speaker-level input, and Recoil's page marks high-level input N/A. Many factory head units have no RCA outputs, so they need a line output converter. Our store lists the Recoil RLOC46-LC, which its listing describes as taking four speaker-level inputs, giving six RCA outputs and providing an amplifier remote turn-on output.
Size: 108 mm or about 101 mm?
Our listing and Recoil's main-site page both give 108 x 125 x 51 mm and, in brackets, 3.97 x 4.92 x 2 in. The 125 and 51 mm figures convert correctly to 4.92 and 2 in, but 3.97 in is about 101 mm, not 108 mm. The Recoil RL880.4 is listed at 3.98 in for the same dimension, yet neither page says which RL680.4 figure is right. Measure the space with a few millimetres to spare before you cut a panel or fix a mounting board.
What owners and reviewers say about the Recoil RL680.4
When we checked in October 2026, we found no owner or reviewer write-ups we could read for the RL680.4. Recoil's main-site page shows Reviews (0) and the model is not on Recoil's US store, so there is nothing from the maker to quote beyond promotional copy.
Compared with the RL880.4 and RL1200.4
The Recoil RL880.4 (₹18,000 MRP) lists 45 W, 50 W and 130 W more at 4 ohm, 2 ohm and bridged for ₹1,000 more at MRP, plus speaker-level inputs, but its listing omits the fuse rating, operating voltage and idle current that this one gives. Recoil's main-site page puts RMS on the RL880.4's 880 W figure but gives these figures no label at all, so the two are not strictly like for like.
The Recoil RL1200.4 (₹30,000 MRP) lists 300 W x 4 at 2 ohm and 520 W x 2 bridged with no 4 ohm per-channel figure. The Recoil RL1100.5 (₹28,000 MRP) adds a fifth channel for a subwoofer.
Who should buy it, and who shouldn't
Buy the RL680.4 if your head unit or processor has RCA outputs, you want four speakers powered from a small case, and you like a listing that states the fuse rating, voltage range and idle current. Our guide to the need for an amplifier in car sound systems covers the basics.
Look elsewhere if you want to use a factory radio's speaker wires without a converter, as the RL880.4 listing allows, or you need subwoofer controls on the amplifier, which the RL680.1 lists.
Installation notes for Indian cars
Run the RCA cables away from the power cable, ground to bare metal and fit the fuse close to the battery. The listing gives no cable gauge, so take that from Recoil's documentation. Monsoon water can collect under mats and in boot wells, so mount the amplifier off the floor. VA3 Car Studio offers professional installation in Ghaziabad and builds speaker pods and door baffles when your speakers need them.
Recoil RL680.4 price in India and where to buy
The RL680.4 carries an MRP of ₹17,000. VA3 Car Studio often sells below MRP, so check the current offer on the RL680.4 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 RL680.4 is the lowest-priced L3 four-channel amplifier we list, with a listing that gives its fuse rating, voltage range and idle current. Its weak points are unlabelled power figures, RCA-only inputs and one dimension given as both 108 mm and 3.97 in. Size speakers from the 95 W per channel at 4 ohm, not the 680 W in the name.
Recoil RL680.4 FAQ
What power does the Recoil RL680.4 deliver?
Our listing gives 95 W x 4 at 4 ohm, 170 W x 4 at 2 ohm and 250 W x 2 bridged at 4 ohm (14.4 V), with no RMS, peak or max label.
Is the Recoil RL680.4 really 680 W?
Four channels at 170 W add up to 680 W, but that is the 2 ohm total. At 4 ohm the four channels add up to 380 W.
Does the RL680.4 have speaker-level inputs?
Our listing gives a low-level input range only, and Recoil's page marks high-level input N/A. Use RCA outputs or a line output converter.
How big is the RL680.4?
It is listed as 108 x 125 x 51 mm and as 3.97 x 4.92 x 2 in, but 3.97 in is about 101 mm, so the first figure disagrees. Measure first.
