Everything goes to one subwoofer. It fits where others do not270 × 112 × 46 mm. Under a seat, behind a side panel, inside a false floor: the boot stays usable and the cable runs stay short. It accepts any sourceInput sensitivity 200 mV – 6 V. High-output head units and DSP processors drive it without clipping the input; low-level factory sources are covered too. Protected, not fragileShort-circuit, thermal and voltage protection with LED diagnostics, 4 × 30 A on-board fuses. It defends itself instead of dying quietly. “Continuous RMS only. No peak, no burst, no marketing watts.” PROFESSIONAL USER MANUAL · 26 PAGES Wiring, loads & impedance, filters, gain calibration and full specifications. ⇩ Download the manual (PDF)English · Rev. 1.0 · September 2026 · 1,3 MB 04Not a box. A case. Black wood, metal latch, pine inside.The SP-1500.1 MINI arrives in a black wooden case with the SP mark and the tricolour on the lid. A rigid shell during shipping, the safest way to store or transport the amplifier afterwards — and a box people keep. In the case: amplifier · collector’s wooden case · printed user manual · 4 mounting screws (3,5 × 20 mm).Not included: power and speaker cable, inline fuse holder and RCA cable — installation materials, chosen for your vehicle. 05Technical specifications POWER OUTPUT — RMS @ 14,4 V, ≤ 1% THD+N Mono 4 ohm 600 W Mono 2 ohm 1000 W Mono 1 ohm 1500 W Minimum load 1 ohm AUDIO Topology Class D, mono, 1 channel Frequency response 10 Hz – 200 Hz S/N ratio ≥ 90 dB Input sensitivity 200 mV – 6 V Inputs RCA, R / L FILTERS Low-pass filter (LPF) 45 – 200 Hz, variable Infrasonic (subsonic) filter 10 – 50 Hz, variable Bass boost 0 – +12 dB, variable POWER SUPPLY & PROTECTION Supply 12 V negative ground, 14,4 V nominal Remote turn-on +12 V On-board fuses 4 × 30 A Recommended cable 4 AWG Protections Short circuit, thermal, voltage Indicators POWER (green) · PROTECT (red) MECHANICAL & QUALITY Dimensions L × W × H 270 × 112 × 46 mm Mounting points 4 Construction Aluminium, heat-dissipating fins, rubber bumpers Terminals Direct-insert, screw clamp PCB 2-layer, surface-mount technology Verification Audio Precision quality control Packaging Collector’s wooden case MANUFACTURER’S LABORATORY DATA · PEAK OR “BURST” FIGURES USED IN SOME MARKETS ARE NOT RMS AND ARE NOT LISTED 06Complete the system SUBWOOFER 12" / 30 CMSP 12CXXX — 2800 W RMSSUBWOOFER 15" / 38 CMSP 15CXXX — 3500 W RMSRECOMMENDED CABLESP 4GA RED 100% OFCLINE PROTECTIONSP AFS4 fuse holder 4 GA 07Before you install it Inline main fuse within 20 cm of the battery, sized to the cable. The amplifier is fused on board at 4 × 30 A, but the battery run must be protected too. Respect the minimum load: 1 ohm. A lower impedance triggers the protection and, if repeated, damages the output stage. Leave the fins free. The aluminium fins are the whole cooling system: never cover the amplifier with carpet, luggage or foam. 12 V systems only, negative ground. Professional installation is recommended: damage caused by improper installation is not covered by warranty. 08Questions installers ask Which subwoofer impedance should I use?Any load down to 1 ohm. A dual 2 ohm voice-coil subwoofer wired in parallel gives 1 ohm and the full 1500 W RMS; the same subwoofer in series gives 4 ohm and 600 W. How many subwoofers can it drive?As many as keep the total load at 1 ohm or above — for example two dual 4 ohm subwoofers, or one dual 2 ohm. Which power cable and fuse?4 AWG power and ground, an inline fuse within 20 cm of the battery sized to the cable, and a ground point on bare metal. Will it fit under a seat?270 × 112 × 46 mm, mounted on 4 points, with the fins left free for air. It is designed for exactly that installation. Does it come with a manual?Yes: a printed manual in the wooden case, plus the PDF above with wiring diagrams, filter settings and gain calibration. Free technical support from Italy.
