Which Alpine Amplifier should I choose?

The BBX series (BBX-T600 and BBX-F1200) is Alpine's budget-friendly Class AB range, suited to straightforward speaker upgrades. The KTP-445A is a unique option for those who already own a compatible Alpine head unit — it plugs directly into the unit and fits behind the dash, boosting four speaker channels to 45W RMS each without additional wiring. The SWA-150KIT is a specialist kit designed specifically for the Alpine SWC-D84S subwoofer system in Fiat Ducato, Citroën Jumper and Peugeot Boxer motorhomes and vans.

The S2-Series uses Class D technology for greater efficiency and higher output. The S2-A36F (4-channel, 360W RMS) and S2-A55V (5-channel, 540W RMS) are Hi-Res Audio certified, with the S2-A55V able to power four speakers and a subwoofer from a single chassis. For dedicated subwoofer power, the S2-A60M delivers 600W RMS and the S2-A120M delivers 1200W RMS — both feature speaker-level inputs for straightforward integration with factory or aftermarket systems.
