The Deaf Bonce ASA-1500.2 is a two-channel Class D amplifier from the Apocalypse range, rated at 1,500 W RMS per channel into 1 ohm, 890 W into 2 ohm and 550 W into 4 ohm at 14.4 V, or 3,000 W bridged into 2 ohm. Its Indian MRP is ₹74,990, the smaller of the two ASA two-channels we sell. It is a subwoofer amplifier at heart: two subs on their own channels, or one big sub bridged. You can check today's offer on our ASA-1500.2 product page.


Deaf Bonce ASA-1500.2 Apocalypse two-channel Class D car amplifier

At a glance

  • Each channel is rated down to 1 ohm, so two low-impedance subwoofers can each get 1,500 W.

  • Bridged, it delivers 3,000 W into 2 ohm or 1,780 W into 4 ohm for a single subwoofer.

  • A 0 AWG power terminal tells you how much current it expects; this is not an amplifier for a stock electrical system.

  • No owner reviews or independent tests turned up when we checked in October 2026.

Figures come from Deaf Bonce's ASA-1500.2 page, which matches our store listing, plus the shared ASA series manual. Neither publishes a fuse rating or a 12 V power figure.


Reading the ratings: 1 ohm, 2 ohm and bridged

Most of the headline number depends on a 1-ohm load. Raise the load to 2 ohm and output falls by about 40%, to 890 W per channel; at 4 ohm it is 550 W, barely more than a third of the 1-ohm figure. So the wiring of your subwoofer coils decides whether you get 550 W or 1,500 W from each channel.


Bridging joins both channels into one. The minimum bridged load is 2 ohm, where you get 3,000 W, the same total as both channels at 1 ohm. Into 4 ohm bridged, the figure is 1,780 W. A subwoofer that can only be wired to 4 ohm therefore gets far more from the bridged amplifier than from either channel alone.


Subwoofer setups that suit it

The neatest match is two Apocalypse SA272 12-inch subs in their dual 2-ohm form. Each is rated at 1,500 W RMS; with its coils in parallel it presents 1 ohm, so one per channel lines up with the ASA's 1,500 W exactly.


A gentler option is two SA252 D1 subs, rated at 1,000 W each with dual 1-ohm coils. Wired in series they present 2 ohm, and each channel's 890 W sits just under their rating. For a single sub, bridge the amplifier into an SA302 D2 with its coils in series: 4 ohm, 1,780 W, against a 2,000 W rating.


Midrange is possible but not the natural job. Four 4-ohm mids per channel make 1 ohm, and each would see about 375 W at full output, more than the 300 W rating of a big mid like the AP-M81AC. For mid walls, a four-channel such as the AAB-500.4D is the better fit.


What it asks of your electrical system

Two channels at 1,500 W add up to 3,000 W RMS, and Deaf Bonce fits a 0 AWG power terminal to carry the current. Run 0 AWG copper for power and ground, keep the ground short and on bare metal, and do the Big 3 upgrade. Deaf Bonce publishes no 12 V figure, and an Indian car idling with the AC on can sit well below 14.4 V, so plan for a high-output alternator or extra battery capacity if you'll use the full 1-ohm rating. The operating range is 9–16 V.


The manual says to place the fuse holder within 40 cm of the battery's positive terminal and not to fit the fuse until all wiring is checked. It gives no fuse value, so size it to protect the cable.


What owners and reviewers say about the Deaf Bonce ASA-1500.2

When we checked in October 2026, we found no owner reviews or independent tests. Deaf Bonce's page has none, and the listing at alphardaudio.us, the website of the US dealer named on Deaf Bonce's site, carried no customer reviews.


The maker's own Russian store, alphardaudio.ru, is promotional but adds detail: it calls this a proven design with Korean circuitry, claims stable operation without overheating, good efficiency and a well-developed cooling system, says the two-channels were upgraded for efficiency and durability, and lists a remote gain controller in the box. A Steve Meade Designs forum search found Deaf Bonce subwoofer threads but nothing on the ASA-1500.2. If you own one, we would like to hear how it holds up.


ASA-1500.2 vs ASA-2000.2 and the Atom monos

The ASA-2000.2 (₹94,990 MRP) makes 2,000 W per channel at 1 ohm and holds on better as the load rises: 1,490 W at 2 ohm, almost this amplifier's 1-ohm figure. It also lists a higher signal-to-noise rating, 95 dB against 91 dB.


For a single subwoofer, a mono is worth comparing. The Atom 3.5K PRO (₹69,990 MRP) reaches 3,500 W at 1 ohm and lists a 12 V figure, but at 2 ohm it makes 2,200 W and at 4 ohm 1,210 W, less than the bridged ASA-1500.2. Choose by how your sub can be wired.


Who should buy it, and who shouldn't

Buy the ASA-1500.2 if you want to run two subwoofers at 1 or 2 ohm each from one amplifier, or one sub that wires to 2 or 4 ohm bridged, and your car's electrics are being built to suit.


Look elsewhere if you mainly want to power speakers, your single sub only makes sense at 1 ohm, or you plan to keep the stock alternator and battery. A four-channel or a mono will serve those cases better.


Installation notes for Indian cars

The manual describes RCA inputs and lists no speaker-level input, so a factory touchscreen head unit needs a line-output converter such as the Machete M6C or a processor like the M8-DSP. At 380 x 240 mm the chassis needs a solid mounting board, ideally where air can circulate rather than under a boot carpet that heats up in summer. Route the bass remote somewhere you can reach it, and use the orange clip LED while setting the gain. VA3 Car Studio in Ghaziabad offers professional installation and can build a custom subwoofer box for the subs you pair with it.


Price and where to buy

The Deaf Bonce ASA-1500.2 has an MRP of ₹74,990. VA3 Car Studio often sells below MRP, so check the current price on our Apocalypse ASA-1500.2 product page. Every amplifier we sell is a genuine Deaf Bonce product.

The bottom line

The ASA-1500.2 makes sense when you plan around its 1-ohm rating: two matched subwoofers, one per channel, with power wiring and charging to match. Wired at 4 ohm per channel it gives away much of its output. With no owner feedback yet, buy it on its published figures and install it carefully.


Deaf Bonce ASA-1500.2 FAQ

Can the Deaf Bonce ASA-1500.2 run two subwoofers?

Yes. Each channel is rated down to 1 ohm, so two subs can each get 1,500 W at 14.4 V. A dual 2-ohm sub with its coils in parallel presents 1 ohm; in series it presents 4 ohm and gets 550 W.


How much power does the ASA-1500.2 make bridged?

Deaf Bonce rates it at 3,000 W into 2 ohm and 1,780 W into 4 ohm when bridged. Do not bridge it below 2 ohm.


Does the ASA-1500.2 come with a bass remote?

The ASA series manual lists a remote control in the package and shows a REMOTE input for a bass remote, and Alphard's Russian store says a remote gain controller is included. Ask us to confirm the box contents.
