Alterum Replacement Subwoofer Box (09-14 F-150 SuperCab)

Smart Solution. The interior of your Ford F-150 truck doesn't come with a lot of storage, which is why installing an under seat storage bin is a smart move. Unfortunately, if your truck also comes with a factory subwoofer, the stock box won't fit in the storage bin. The solution is this Alterum Replacement Subwoofer Box, which is designed to slide right into the bin and be held firmly in place. With a single plug, the subwoofer can be quickly and easily removed when you need to transport larger items. As well this set up provides an up-fire position giving you more sound travel over the factory subwoofer's down-fire position. 

Quality Construction. The Alterum Replacement Subwoofer box is made in the USA from an impact-resistant polymer that works to cushion the speaker against any blows and is designed to perfectly fit in under seat storage box (sold separately).  

Application. This Alterum Replacement Subwoofer Box is designed to fit perfectly the ,  or  Underseat Storage System for the 2009-2014 F-150 SuperCabs.
