SUPER POWER AUDIODESIGNED IN ITALY
MMXXVI
300 watts RMS
per channel.
Two channels for the front stage — or one bridged channel at 940 W RMS for a subwoofer. The crossover is on board, so it works with a factory head unit and with a DSP. Designed in Italy, verified with Audio Precision instruments before it leaves the line.

Why this amplifier
Stereo onto a pair of speakers, or bridged mono at 940 W RMS onto a 4 ohm subwoofer. One amplifier covers both jobs and you decide at installation, with the bridging guide printed on the terminal panel.
230 × 112 × 46 mm. Under a seat, behind a side panel, in a false floor: the boot stays usable and the cable runs stay short.
High-pass, low-pass or off, both variable from 50 to 250 Hz, plus bass boost from 0 to +12 dB. Door speakers filtered high or a subwoofer filtered low, with no external crossover to buy.
Input sensitivity 200 mV – 6 V, and it still works from 100 mV. High-output head units and DSP processors drive it without clipping the input; low-level factory sources are covered too.
Wiring, loads and impedance, filters, gain calibration and the complete specifications.

Not a box. A case.
The SP-300.2 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 carry the amplifier afterwards — and a box people keep.
In the case: amplifier · collector’s wooden case · printed user manual.
Not included: power and speaker cable, inline fuse holder and RCA cable — these are installation materials, chosen to suit your vehicle.

Complete the system
Before you install it
- Inline main fuse within 20 cm of the battery, 60 A recommended and sized to the cable. The amplifier carries 2 × 30 A on board, but the run from the battery has to be protected too.
- Respect the minimum load: 2 ohm per channel in stereo, 4 ohm bridged. A lower impedance trips the protection and, if it happens repeatedly, damages the output stage.
- Leave the fins clear. The aluminium fins are the entire cooling system: never cover the amplifier with carpet, luggage or foam.
- 12 V systems only, negative ground. Professional installation is recommended: damage caused by incorrect installation is not covered by the warranty.
