Holden Colorado Subwoofer add on Value and Performance pack

We take pride in providing a market leading premium product, many hours have been spent in manufacturing and development. To help keep the sell Prices lower, we only sell as a package with products. This also helps us guarantee speaker fitment. The tolerances are extremely tight, so not "any" sub fits.

Our Holden Colorado Stereo upgrade is the the best option on the market, we have developed the only Box that allows for  a quality 10 inch Subwoofer without sacrifice furthermore they are all hand built in Australia to the highest standards.

Time as been taken to create very clean fit with a sorrounding lip to help with the modification of the plastic on the rear wall . We do offer custom covering options as result this means your can option for other colours or fabrics.

We have taken a lot of time with the design of these box's to ensure a seamless look, even the recessed sub mounts to offer more protection for the subwoofer face

Due to the limitations of space for a Stereo in a Holden Colorado it was always going to be a challenge to achieve decent volume, this 4 x 8 inch solution is the ultimate way to get serious bass in an almost impossible situation.
