Do I need a separate amplifier for a car subwoofer?
Reviewer consensus
It depends on the sub. Passive subs like the Skar SDR/EVL series and Rockville K6 require a dedicated monoblock amplifier matched to their RMS rating. Powered/loaded enclosures like the Kicker PTRTP and Rockville SS10P have a built-in amp and only need power, ground, and a signal input, which is why specialist communities recommend them for first-time installs.
