Key Features

Trex12 3000 watts subwoofer with Bass Box - DB Audio Systems TREX12 + BX12

DB Audio has released the new T-Rex range of subwoofers into the wild. With up to 3” hi-temp 4-layer voice coils and 200 oz double stacked magnets, these DB Audio T-Rex monsters have the power and control you expect from a world class product. By using the best materials like Kevlar woven, paper cones, they ensure the subwoofer has a dual 2ohm impedance and chrome push terminals so you know you are going to get the best sound available.

To dominate with SPL and excursion, look no further than DB Audio as it’s possible to put 1000W RMS up each of these heavyweight big hitters. 1 cu/ft box (Vb) recommended tuned to 31hz. 

British Design

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

Bass Reproduction

This In Phase sub offers superb bass reproduction using high quality materials. When using the right enclosure and amp, you could be hitting sub 30Hz!

Premium Box

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. 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. The sealed technology allows a tight bass output instead of a loose and unfiltered bass output. This allows accurate bass as well. 


The DB Audio Trex series subwoofers use a non-pressed paper cone, which is rigid and higher enduring. This is reinforced with Kevlar technology producing a hard hitting, SPL busting monster.

Power output

This sub is build for SPL. So it offers an outrageous 1000W RMS power output and 3000W Peak Power output. Combine this with the In Phase IPA2001D, your windscreen might just fly off! 

a few words from a Car Audio Centre staff member-

"The DB Audio TREX and Xtinct series subwoofers are absolute monsters. Offering different levels of SPL. The TREX giving the high level SPL and the Xtinct giving the super high level SPL performance. I have never come across negative feedback about these subs. They are recognised and loved

Oh my GOD, THESE GUYS WERE NOT KIDDING!!! I had to replace my 2 x 12" alpine SWR woofers, never thought this one sub would leave my two alpine subs standing. Firstly the build quality on this sub is like a tank. It's so impressive. Made my Alpine subs look like baby speakers! The power and output from this one subwoofer compared to my old ones is mind blowing. The bass is sooo powerful. I'm in love. Going to get a second one soon.

cant here myself think

    I am after a duel sub box for 2 12inch 3000w trex subs powered by an ipa4000 amp do you sell the box ?


    we would suggest for the subwoofer's you have to have a custom box built, as most box's that are prefabbed wouldn't be ideal for something like dbaudio Trex's running off a IPA4001D, our stores offer a box building service i would recommend you visit one of our stores
