Deaf Bonce MMA-1100.1D Review: A Slim Monoblock That Publishes Its 12 V Power
Updated: Oct 7
The Deaf Bonce MMA-1100.1D is a mono Class D subwoofer amplifier from the Machete line, rated at 1,100 W RMS into 1 Ω at 14.4 V and, unlike the MLA monoblocks, also at 1,000 W into 1 Ω at 12 V. It makes 650 W into 2 Ω and 400 W into 4 Ω, and lives in a slim 132 x 305 x 47 mm chassis. Its India MRP is ₹26,990, between the MLA-1000 and the MLA-1500 in our range. It suits a single large subwoofer, or a pair of 8-inch drivers, where mounting space is long and narrow. Today's price is on our MMA-1100.1D product page.
Quick summary
1,100 W at 1 Ω (14.4 V), 1,000 W at 1 Ω (12 V), 650 W at 2 Ω and 400 W at 4 Ω.
Low-pass 40–180 Hz, subsonic 0–50 Hz and a bass boost at 45 Hz, with a damping factor of at least 120.
The manual lists a 6 AWG power terminal and no internal fuse.
A narrow 132 mm chassis that needs about half the mounting area of the MLA-1000.

Power, filter, damping, voltage and size figures come from Deaf Bonce's MMA-1100.1D product page and match our listing. Terminal sizes, the fuse note, the bass boost range and the installation guidance come from the owner's manual, which also covers the smaller MMA-550.1D.
Why the 12 V rating matters
Most amplifier ratings assume 14.4 V, the voltage a healthy charging system holds with the engine running. Real cars don't always deliver it. Sitting in traffic at idle with the AC and headlights on, or playing with the engine off, the supply drops towards 12 V, and an amplifier's output drops with it. Deaf Bonce's MLA monoblocks quote 14.4 V figures only; the MMA-1100.1D also tells you what to expect lower down.
Here the difference is 100 W, roughly 9 per cent of the 14.4 V rating at 1 Ω. That gives you a more realistic number for comparing amplifiers in a car that often runs below its charging voltage. The amplifier keeps running down to 9 V, so it should keep playing through voltage dips, though with less output.
Wiring it correctly
Two details in the manual shape the installation. First, the power terminal is listed as 6 AWG (13.3 mm²) and the speaker terminals as 14 AWG (2.08 mm²), smaller than the 4 AWG and 8 AWG terminals on the MLA-800 and MLA-1000. If you plan a thicker main run, you will need a distribution block or reducer at the amplifier end. Second, the manual lists no internal fuse for the MMA-1100.1D, so the fuse holder it places within 40 cm of the battery's positive terminal is the only protection for the power cable. Size that fuse to the cable, and if in doubt ask us.
The manual describes a REMOTE input for a bass remote control, but its box contents list only the amplifier, manual, warranty card and mounting kit. If you want a dash-mounted bass knob, check with us before ordering.
Subwoofer pairings
These are our own calculations from published ratings, not Deaf Bonce recommendations. A Machete MF-12R in its dual 2 Ω version, coils in parallel, presents 1 Ω and sees up to 1,100 W against its 1,200 W RMS rating, a well-judged match; the MF-15R works the same way if you want a 15-inch. For twin 8-inch drivers, two MF-08S in dual 4 Ω form, each wired to 2 Ω and then paralleled to 1 Ω, share the output at about 550 W each against their 600 W ratings.
What owners and reviewers say about the Deaf Bonce MMA-1100.1D
When we checked in October 2026, we found no owner reviews, forum threads or independent tests of the MMA-1100.1D that we could read and verify. Deaf Bonce's product page and manual carry specifications only. The only listing we found at Alphard Audio, the US dealer store named on Deaf Bonce's site, was for a refurbished unit, with no customer reviews. Large marketplaces and car forums were blocked to us or had nothing on this model.
So we can't report an owner consensus. If you have run an MMA-1100.1D, tell us how it has coped with heat and long sessions; it would help the next buyer.
MMA-1100.1D vs MLA-1000, Atom 1300.1 PRO and AAP-800.1D
The MLA-1000 (₹25,990 MRP) costs ₹1,000 less and makes slightly more at 2 Ω (680 W) but less at 1 Ω (990 W), quotes no 12 V figure and needs a 350 x 216 mm footprint. Its manual also lists a phase control, an RCA output and a remote in the box, none of which appear in the MMA-1100.1D's manual.
The Apocalypse Atom 1300.1 PRO (₹27,990 MRP) is the strongest alternative: ₹1,000 more for 1,300 W at 1 Ω, 1,020 W at 12 V and listed high-level inputs, in a 180 x 140 x 54 mm case. The AAP-800.1D (₹23,990 MRP) also quotes a 12 V figure, 700 W, if 790 W at 1 Ω is enough.
Who should buy it, and who shouldn't
Buy the MMA-1100.1D if you want around a kilowatt for one 1,200 W subwoofer or two 8-inch drivers, value a published 12 V rating, and have a long, narrow mounting spot, such as behind a seat back or along the side of the boot.
Look elsewhere if you want a 4 AWG power connection without a reducer, a phase control or a remote listed in the box, or the most power near this price. The Atom 1300.1 PRO deserves a look first for power, a 4 AWG terminal and a remote in its manual's box list; the MLA-1000's manual lists a phase control.
Installation notes for Indian cars
The manual asks for a mounting place that stays between 0 °C and 55 °C and warns the amplifier may reach 80 °C in operation. Its slim shape tempts people to tuck it into tight cavities; leave air around it, particularly through an NCR summer. Fix it firmly, because rough roads find any loose screw.
Keep RCA leads away from the power cable, confirm the final subwoofer impedance before connecting, and set the gain with a test tone. VA3 Car Studio in Ghaziabad offers professional installation and can build a custom subwoofer box.
Price and where to buy
The Deaf Bonce MMA-1100.1D has an MRP of ₹26,990. Check today's price and stock on our Machete MMA-1100.1D listing, which describes it as a genuine Deaf Bonce product, and ask us about India warranty terms.
The bottom line
The MMA-1100.1D is a slim, kilowatt-class monoblock that, unlike the MLA monoblocks, also quotes its output at 12 V: 1,000 W at 1 Ω, against 1,100 W at 14.4 V. Its 6 AWG power terminal, lack of an internal fuse and modest feature list need planning around, and the Atom 1300.1 PRO is a close rival. Matched to an MF-12R and wired with care, it is a sound choice for a narrow mounting space.
Deaf Bonce MMA-1100.1D FAQ
What does the 12 V rating of the Deaf Bonce MMA-1100.1D mean?
It is the output Deaf Bonce quotes when the supply is 12 V, as with the engine off or a sagging battery: 1,000 W at 1 Ω, against 1,100 W at 14.4 V. It shows how much power to expect when your car's voltage is below its charging level.
Does the MMA-1100.1D have an internal fuse?
No. The manual lists no internal fuse for the MMA-1100.1D, so the fuse holder within 40 cm of the battery's positive terminal is essential. Size the fuse to protect the power cable you install.
What power cable does the Deaf Bonce MMA-1100.1D take?
The manual lists a 6 AWG (13.3 mm²) power terminal. If you run thicker cable from the battery, use a distribution block or reducer at the amplifier, and size the fuse to the cable.
