Alpine PWE-S8 Compact powered subwoofer with 8" sub and 120-watt amp

What stands out:

• Featured in our article: Best car powered subwoofers for 2026
• The non-resonant cast-aluminum housing maximizes the performance of the high-excursion 8" sub
• This sub can accept low-level or speaker-level signals, so it'll drop into almost any system
• Alpine includes a remote control with a 15-foot cable, so you can adjust the bass from the dash

Keep in mind:

• This sub does not include wiring, so you'll need to purchase a 10-gauge wiring kit
• You'll need to wire this sub to your battery
• Measure the intended installation spot for fit — dimensions are 13.4"W x 2.875"H x 9.062"D
• If you use the sub's line level inputs, you'll also need an 18-gauge remote turn-on lead
