What kind of speakers does this fit?
This product includes a pair (2 separate enclosures) precision-built to house two (2) standard 6"x9" oval car audio speakers or subwoofers (one speaker per enclosure). It is engineered for a seamless fit with standard 6x9 speaker footprints requiring a maximum mounting depth of 3.75".

Will they fit in my vehicle?
Yes, these enclosures feature an ultra-compact, shallow rectangular layout optimized for placement on rear parcel shelves, cargo decks, truck cabins, or trunk utility areas. This modular twin-box configuration allows you to easily position each cabinet on the left and right sides of your setup to achieve ideal stereo separation. The exact external dimensions for each individual enclosure are 11.25" W x 8.50" H x 4.25" D.

How is the performance and wiring?
Each enclosure in this pair operates as a completely independent, airtight sealed chamber. This separate-cabinet design prevents pressure interference between channels, ensuring exceptionally clean, tight mid-bass response and vocal clarity from your 6x9 speakers. The airtight acoustic environment also protects the speaker cones from back-wave distortion, significantly improving power handling. Each cabinet comes equipped with its own integrated speaker terminal cup for quick, secure, and reliable wiring connections.

I stay on your foot they don’t slip in your shoe
Number of Items: 3, Color: White/Neutral (3-pairs), Size: Medium
This is the only socks I wear Under Armour because they stay in place I wear a size 8, but they’re more comfortable with a large instead of a medium, but I wear both because I have them already and you can pull them to stretch them out a little bit
