If you're looking for a great bass upgrade for the factory sound system in your Hyundai i30, AV-DC can custom-build and install an upgraded sound system! This example includes a custom subwoofer enclosure built especially for this i30 N which fits flush in the side panel of the hatchback. It contains a 10 inch 280 watt subwoofer from Focal, paired with an amplifier which works with your factory touchscreen sound system.
The i30 subwoofer upgrade package fits without any permanent modifications to the i30 and can be removed without a trace if needed. Best of all, it gives it a fantastic bass upgrade which doesn't use up precious boot space! The Focal 10" subwoofer is capable of great bass depth and output.
