Why this amplifier
A single output stage delivers its full rated power into 1 ohm: no bridging, no compromise between two channels. Everything goes to one subwoofer.
270 × 112 × 46 mm. Under a seat, behind a side panel, inside a false floor: the boot stays usable and the cable runs stay short.
Input 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.
Short-circuit, thermal and voltage protection with LED diagnostics, 4 × 30 A on-board fuses. It defends itself instead of dying quietly.
Wiring, loads & impedance, filters, gain calibration and full specifications.

Not a box. A case.
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.

Complete the system
Before 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.
