Review on 🔊 Enhance Your Chevy C10 with ENIXWILL Behind Seat Speaker Brackets for 6x9 Speakers (1973-1987 Squarebody) by David Silva

Brackets fit well, overall slightly larger than they should be. You need to get in from the top first, with the top edge going behind the sheet metal, and then rotating the bottom one. It fits very tight from top to bottom and is well pressed at the back and sides. Won't work with a cardboard tray (this would require cutting the corners and trimming the bottom to fit the speaker. No tilt up and down to fit under the cardboard tray. Also absorbing material would need to be trimmed. I would give 5 stars if since it would be aluminum and a little more at the top and bottom, I would buy it again.
