Key Features

12" Subwoofer and Amp Package with Wiring Kit - Pioneer GXT-3730B-SET

Improve your sound system with this Pioneer Subwoofer and Amplifier package, designed to be easy to install, whilst offering strong powerful bass.

The 30cm / 12' subwoofer features strong reinforced IMPP™ subwoofer cone for minimum distortion and high reliability.

The included amplifier is compact yet powerful. It's handy 'Auto Turn ON/OFF' feature allows you to easily connect to audio systems using speaker inputs. The built in LPF (Low Pass Filter) ensures the subwoofer receives the ideal frequency range for hard, solid bass. Not only is it easy to connect, it’s also super easy to set up meaning you'll begin feeling the bass in no time.

The Pioneer GXT-3730B-SET subwoofer and amplifier package consists of; 1 x TS-A30S4 subwoofer, a sealed enclosure, 1 x JA1201D amplifier, and 1 x amplifier cable set for easy installation.

Bass Reproduction
This sub offers superb bass reproduction using high quality materials. When using the right enclosure and amp, you could be hitting sub 35Hz!

This sub uses a strong IMPP composite cone which is far more dense than traditional paper cones allowing the sub to endure more power. The double Ferrite magnet keeps the sub flexing and pushing bass waves out to a higher standard.

Power output
This sub is build for a perfect balance of SPL and SQ. So it offers a humble 400W RMS power output and 1400W Peak Power output.

Designed to enhance your in-car audio experience, the powerful JA1201D gives you total installation freedom and very low distortion. With a one-body heat sink and gain adjustment of up to 6.5V, you can turn your in-car audio experience into the sound staging environment that you’re looking for.
