Questions and answers

Which hits harder, the JBL BassPro 12 or the Kicker 51HS8?
The JBL BassPro 12 should hit harder. Its 12-inch driver in a ported box moves more air than the Kicker's 8-inch sealed sub, even though both run 150 W RMS.
Which fits in a small car?
The Kicker 51HS8. It is 3-1/8 in tall and 9.4 lbs, so it fits under many seats. The JBL BassPro 12 is a full-size ported box that needs trunk space.
Does the Kicker 51HS8 need an aftermarket radio?
No. It works with nearly any factory or aftermarket head unit and includes a preamp signal adapter and power wiring.
Which plays lower, 25 Hz or 35 Hz?
The Kicker 51HS8 is rated down to 25 Hz and the JBL BassPro 12 to 35 Hz. The Kicker's sealed box trades some output for that lower reach.
Is the Kicker 51HS8 worth the extra money?
It depends on space. At $288.94 at Walmart as of November 3, 2026, the Kicker buys a compact plug-and-play package with remote bass and crossovers. If you have trunk room and want more output, the JBL BassPro 12 may cost less.
Can I keep my factory radio with either sub?
Yes for the Kicker 51HS8, which lists factory head unit compatibility and includes a preamp adapter. The JBL BassPro 12 takes speaker-level or line-level input, but its wiring kit is not listed here.
