The downward-firing design protects the subwoofer from damage while enhancing bass response, making it perfect for work vehicles, family SUVs, and off-road builds.
Integrated 400-Watt Amplifier
Unlike traditional subwoofer systems that require a separate amplifier, the PTRTP10 features a built-in power-matched amplifier delivering 400 watts of clean, efficient bass performance. This simplifies installation while ensuring the enclosure performs exactly as Kicker intended.
Innovative CompRT™ and reFLEX™ Technology
Kicker's advanced design pairs an active CompRT™ subwoofer with a passive reFLEX™ radiator to maximise bass output and efficiency. This combination produces deeper, more powerful low frequencies than traditional compact powered subwoofers while maintaining exceptional sound quality.
Easy Factory System Integration
Whether you're upgrading a factory stereo or an aftermarket head unit, the Kicker PTRTP10 integrates easily into almost any vehicle audio system. Included remote bass control allows you to adjust bass levels from the driver's seat to suit your music and listening preferences.
