Recoil DII700.4 Review: Compact 4-Channel Amplifier Rated 95 W RMS x 4
The Recoil DII700.4 is an ultra-compact Class D four-channel amplifier that Recoil rates at 95 W RMS per channel into 4 Ω and 150 W RMS per channel into 2 Ω at 14.4 V, or 300 W RMS x 2 when bridged into 4 Ω. Its Indian MRP is ₹32,000, the lowest of the four DII amplifiers we list, and it suits a door-speaker upgrade in a car with little spare room. You can see it on our Recoil DII700.4 product page.
Key takeaways
Recoil's RMS rows give 95 W x 4 into 4 Ω, 150 W x 4 into 2 Ω and 300 W x 2 bridged into 4 Ω, all at 14.4 V. The max figures printed around them are not RMS.
It takes RCA or speaker-level input, has a 2/4-channel input switch and offers REM, VOX or DC turn-on.
Recoil's page says DII series boards are conformal coated against dust and water, but it publishes no ingress rating.
We could not find an independent owner review, so the advice below rests on Recoil's published figures.

Figures come from Recoil's DII700.4 page and our store listing, which agree. Recoil's US web store page prints different power figures (110 W x 4 into 4 Ω, 160 W x 4 into 2 Ω, 340 W x 2 bridged) with no RMS label in the text we could read, so we have not used them. Recoil's general warranty page describes US terms and does not name this amplifier.
Reading the DII700.4's power figures
Three headline numbers sit around this amplifier. Our product name says 700W, Recoil's page text says 800 Watts Max Power, and its page title says Max 1,400 Watts. The RMS rows add up to 380 W across four channels at 4 Ω and 600 W at 2 Ω, below all three headlines. Recoil labels the 800 W and 1,400 W figures as max, so match speakers to the RMS rows.
Ninety-five watts of continuous power per channel is well above what most head units supply, and it is a comfortable level for many door speakers, so check each speaker's own RMS rating against it. The 150 W figure applies only to a 2 Ω load, so most buyers should plan around the 4 Ω row.
Inputs, turn-on and channel layouts
Recoil lists RCA and speaker-level inputs, so the amplifier can take a head unit's pre-outs or a factory radio's speaker wires. Its US page describes the 2/4-channel switch as being for stereo or four-channel source signals; in general, the two-channel setting lets a head unit with a single RCA pair feed all four channels. The REM, VOX and DC modes cover a remote wire, signal sensing and DC-offset sensing, and the US page says no dedicated remote wire is then needed. Test the turn-on on your own car before closing up the panels, because factory radios differ.
The common four-channel layouts are front and rear pairs, or a front pair plus a bridged pair driving a 4 Ω subwoofer at the 300 W RMS bridged rating. Recoil lists a high-pass and a low-pass filter, each 30 Hz – 300 Hz, but does not say how they are assigned to the channels, so confirm that in the manual before planning a front-plus-subwoofer layout. A dedicated mono amplifier such as the Recoil DII3300.1 avoids the question.
What owners and reviewers say about the Recoil DII700.4
When we checked in October 2026, we could not find an independent review, an owner thread or a retailer review page for the DII700.4. Recoil's own page shows no customer reviews, and neither does the matching page on its US web store. Some retailer and video sites block automated reading, so a review may exist that we could not open, but we have nothing from owners to report and will not guess at a consensus.
Noise floor, heat behaviour and long-term reliability are not documented anywhere we could read, so we make no claims about them. If you already run a DII700.4, tell us how the turn-on mode and gain setting worked in your car.
DII700.4 vs DII1400.5, DII3300.1 and the L3 four-channel amplifiers
The Recoil DII1400.5 (₹40,000 MRP) adds a fifth, mono channel for a subwoofer, so one box can run a front stage and a sub. Its power figures carry no RMS label on Recoil's page, so do not set them directly against the DII700.4's RMS rows. If you would rather run a separate subwoofer amplifier, the DII3300.1 (₹45,000 MRP) is a mono model with RMS-labelled ratings.
If four channels are all you need and budget matters, we also list Recoil's L3 four-channel RL880.4 (₹18,000 MRP) and RL680.4 (₹17,000 MRP). Compare each one's load, voltage and power label with the DII700.4's RMS rows before deciding which is stronger.
Who should buy it, and who shouldn't
Buy the DII700.4 if you want RMS-labelled four-channel power from a small box, you are driving door speakers or a front stage, and you are comfortable relying on Recoil's published figures because owner feedback is thin.
Look elsewhere if you want a subwoofer channel built in (the DII1400.5 has one), or if you will only buy after reading independent reviews, because we found none. Our guide on whether you need an amplifier in your car covers the basics first.
Installation notes for Indian cars
At 158 x 136.5 x 53 mm the amplifier is small enough to go under a seat or behind a panel, but leave air around the heatsink. Recoil lists efficiency as 78% at 4 Ω, so some of the power it draws still becomes heat. Recoil's page says DII series amplifiers use a conformal-coated board that protects against dust and water. That is relevant to dust and monsoon humidity but it is not a waterproof rating, so keep the amplifier clear of floors where water collects, and fix it firmly because rough roads shake loose a box that only rests on a panel.
The ratings are quoted at 14.4 V. In slow traffic with the AC running, the voltage at the amplifier can sit lower and the output falls with it. Recoil lists a 50 A (ATC) fuse rating but publishes no cable gauge, so take the cable size and the fuse value near the battery from the manual in the box. VA3 Car Studio in Ghaziabad offers professional installation, and we can build door baffles or speaker pods if you are fitting new door speakers.
Price and where to buy

The bottom line
The DII700.4 is a small four-channel Class D amplifier with clearly labelled RMS ratings: 95 W per channel into 4 Ω, 150 W into 2 Ω and 300 W bridged into 4 Ω. Ignore the 700, 800 and 1,400 W headlines, confirm the filter assignment in the manual, and budget for a careful install. We found no independent owner reviews, so judge it on the published figures.
Recoil DII700.4 FAQ
Is the Recoil DII700.4 rated in RMS?
Yes. Recoil's page labels 95 W x 4 at 4 Ω, 150 W x 4 at 2 Ω and 300 W x 2 bridged at 4 Ω as RMS at 14.4 V. The 800 W and 1,400 W figures on the same page are labelled max and are not RMS.
Can the DII700.4 run from a factory radio?
Recoil lists speaker-level inputs and REM, VOX or DC turn-on, which are the usual routes for a factory-radio install. Test the turn-on mode on your own car before you close up the panels.
Can the DII700.4 drive a subwoofer?
A bridged pair is rated at 300 W RMS into 4 Ω, so a 4 Ω subwoofer can run from two channels. Recoil does not say how its filters are assigned to channel pairs, so confirm that in the manual before you plan a front-plus-subwoofer layout.
