Bridge two, get 180 W Bridged, two channels deliver 180 W RMS each at 4 ohm — enough for a pair of midranges or a small subwoofer, without adding a second amplifier. Class AB, the whole band 20 Hz – 20 kHz with THD below 0.1% and a signal-to-noise ratio above 94 dB. Linear class AB topology, not a switching output stage. Filters where you need them Low-pass 50–250 Hz and high-pass 120 Hz–3 kHz, plus bass boost 0–12 dB: the same amplifier drives mids, coaxials or a bass channel. “Continuous RMS only. No peak, no burst, no marketing watts.” 03 Controls and connections USER MANUAL (PDF) Wiring, loads & impedance, filters, gain calibration and full specifications. ⇩ Download the manual (PDF) English · 2026 04 What you receive Amplifier, ready to install.

Use a cable section suited to the current and a main fuse within 20 cm of the battery. Clean chassis ground. Ground on bare metal, scraped free of paint, with the shortest cable you can run. Leave it ventilated. Class AB heats up: mount the amplifier with free air around it and never cover it with carpet, luggage or foam. Set the gain to the source, not to maximum. The input takes 0.2 V to 5 V: match it to your head unit instead of turning the gain fully up. 08 Questions installers ask How much power does each channel give?60 W RMS per channel at 4 ohm and 90 W RMS per channel at 2 ohm, on all four channels. Can I bridge it?Yes. Bridged it works as a 2 channel amplifier with 180 W RMS per channel at 4 ohm. Is it class D?No. The SP-60.4 AB is a linear class AB amplifier, with THD below 0.1% over 20 Hz – 20 kHz. Can I use one channel pair for bass?Yes. The low-pass filter covers 50–250 Hz and the bass boost adds up to 12 dB, so a bridged pair can drive a bass channel. Which voltage does it need?A 12 V system: it operates between 9 and 16 V.
