PowerBass PS-AWB121T 12″ Amplified Slim Subwoofer | Big Bass

PowerBass PS-AWB121T 12″ Amplified Thin Enclosure

Want bone-rattling bass but think you haven’t got the space for it? Think again. At Safe and Sound, we’ve spent over 30 years helping drivers upgrade their in-car audio — and the PowerBass PS-AWB121T is one of the smartest ways to add serious low-end to almost any vehicle.

This all-in-one slim subwoofer enclosure packs a 12″ woofer and a built-in amplifier into a space-saving cabinet designed to tuck under or behind your seat. No separate amp. No bulky box eating your boot. Just deep, tight, punchy bass exactly where you want it.

Big Sound, Small Footprint

PowerBass engineers designed the woofer to fit the box — not the other way around. The result is a deeper, tighter bass response that handles more power for your money. The aircraft-grade vinyl finish keeps it looking sharp and standing up to everyday wear.

• Injection-moulded PP cone with large-roll butyl rubber surround
• 2″ KSV voice coil former for clean, controlled output
• Computer-optimised, sealed cabinet for accurate, defined bass

The integrated 1-channel Class A/B amplifier means there’s nothing extra to buy. Fine-tune your sound with the onboard controls and the included wired remote gain so you can adjust your bass on the fly — right from the driver’s seat.
