Which has more bass, the Kicker HS8 or the JBL BassPro Hub?

The JBL BassPro Hub. Its 11-inch woofer and 200-watt RMS amp move more air than the Kicker's 8-inch driver and 150 watts. The Kicker still plays down to 25Hz in a small sealed box.

Is the JBL BassPro Hub worth the extra money?

If you have a spare tire well and want hidden bass with a full remote, yes. At $439.95 at Best Buy as of November 3, 2026 it costs about $151 more than the Kicker at $288.94 at Walmart, and you get 50 more watts and a bigger driver.

Will the Kicker 51HS8 fit under a car seat?

Usually yes. It is 3-1/8 inches tall, 9-3/8 inches wide and 13-7/8 inches deep, and it comes with straps and mounting hardware. Check the space under your seat before buying.

Does the JBL BassPro Hub fit any car?

No. It is designed to sit in the hub of a spare tire, so your car needs a spare tire well with enough depth. Cars with a tire repair kit instead of a spare will not take it.

Which is easier to install?

The JBL is simpler if you have a spare tire well: it drops in and uses the included wiring harness. The Kicker needs a flat mounting spot and straps or screws, but its plug-and-play adapter works with nearly any head unit.

Do either of these need a separate amplifier?

No. Both are powered subwoofers with built-in Class D amps, so you connect power and signal and they run on their own.

The Kicker 51HS8 is the better pick for most shoppers: it costs $288.94 at Walmart as of November 3, 2026, versus $439.95 at Best Buy for the JBL BassPro Hub. The JBL wins on power and on hiding completely inside the spare tire hub, with 200 watts RMS against 150. Buy the Kicker if you want strong bass for less money and have a shallow spot to mount it. Buy the JBL if you have a spare tire well and want bass you never see.
