Key Features

1400W 12" single 4Ω voice coil subwoofer - Juice Car Audio JS12

Just because it’s small don’t discount it. The Juice JS series manages to put bass in any vehicle will very little modification without emptying the bank. The JS Series subwoofers are capable of 1000W+ peak power and very low frequencies. This combination kicks out awesome sounding bass and plenty of power.

Passengers will be blown away and left questioning whether you’ve equipped the boot with a 15-inch woofer once they’ve heard this combination slam, subtlety and immediacy of bass response.

For tight, punchy, melodic bass there’s no need to listen elsewhere. If you actually want musicality rather than outright soul destroying, window rattling, this 12-inch could be the perfect woofer for the job. 

British Design

All Juice audio products are designed in the UK utilising over 30 years of audio experience to create a sound that is right for you.

Enclosure Type Subwoofer

This sub is designed to be installed in an enclosure sealed or bass reflex enclosure will suffice. Open air installs can reduce power output.

Power output

JS12 1400W 12" svc 4Ω
Simon Chambers on 21/07/2018 5 star rating

Running a pair of these in a mid range box @2 ohm 850w. Very pleased, hits very hard and for the price I'm extremely impressed. As loud and clear as my 4x12" Explod/Fli setup.

Cheap and very cheerful
Darren D on 06/02/2013 5 star rating

Using this sub in a sealed 1 cubic foot box, running off a Juice JA890 amplifier. Am thoroughly impressed with this, especially for the price <�35. Plent of bass for a hatchback and even hits the lows really well, quality sub and as always quality service from CAC.
