Key Features

Box Deal! 12" Sub with Ported Subwoofer Enclosure and IPA3001D In Phase Amplifier - DB Audio TREX12

Choosing a bass box can be hard as not many people sell them and ideally they need to be built by people who know subwoofer parameters, box design and understand how sound waves travel. Not to mention, have joinery knowledge.

Our expertly designed boxes will fit into a majority of vehicles. Our box's panels are 20mm thick and we use high density MDF only for enhanced durability. This enables the box to have a long life and great bass performance.

When shopping online for a box, be careful. A lot of boxes will be advertised for £15-£35 and are often made from inferior MDF and unsustainable sources. Not to mention, sealed badly. This kills off the tight accurate bass you are seeking
This kit includes: 
1x DB Audio T-Rex12 Subwoofer
1x In Phase IPA3001D
1x JWTRU21 Amp wiring kit
1x Ported Bass Box 

To dominate with SPL and excursion, look no further than DB Audio's T-REX sub. With a magnet almost as big in diameter as the woofer itself, the DB Audio TREX subs produce truly prehistoric subsonic lows and the sort of low frequencies that should never be underestimated.

Slot Ported-
The slot port allows bass waves to travel further giving a much louder effect.


The New InPhase IPA range of amplifiers from InPhase is possibly one of the best car amplifiers available today. The advanced features such as bass boost, fully variable zero to 60Hz subsonic filters and crossover network help to provide that intense bass you're after as well as providing great power for the sub.

Wiring Kit-
The JWTRU21 2 Gauge High Power Amplifier Wiring Kit 3800W is kit you need when fitting deal, it is especially designed to maximise the performance of any amplifier.

High Quality Carpet-
The Soot Black carpet has high grade fibres commonly found in industrial carpet used in offices and schools, whilst maintaining a soft to touch texture. This compliments the expert box design to go with it.

MDF Like No Other-

The box structure is fabricated from high density MDF that has similarities to high end laminate floors. Made for performance without compromise. Enjoy tight bass in your car with a proper made box.

Binding Post-
The binding post is made from high quality plastic will metal terminals plated with a gold finish.


Instead of loose and unstable sounding bass, you can have softened bass that sounds amazing thanks to the synthetic filling.
