Loose boxes always look rigged, and can really provide a hazard in a Panic stop situation.
This add-on to the existing rear shelf got everything mounted in a secure fashion, and allowed space for a 10" Infinity woofer. From a system that always sounded weak, I was able to achieve a clean, full sound using their existing amp to drive the woofer. The Stereo was able to provide plenty of Highs, and I put the power where it would do the most good.
