Alpine® Universal Mono Subwoofer Power Pack

Model #: KTP-190U
At a Glance
Alpine's KTP-190U "Power Pack" mono amplifier can power a 2-ohm sub with 60 watts RMS, yet this compact amp will fit behind most dashboards for a truly stealthy installation. The KTP-190U can also send 90 watts to a 1-ohm load safely, so it's a great choice as a replacement amp for a low-impedance factory sub. The KTP-190U will work with most non-premium factory radios and aftermarket receivers, but it's not a plug-and-play installation — you'll have to wire it into your system.
