This is the solution to your low quality dash speakers. The aftermarket ausio industry offers a much wider selection of 5.25″ than 4"x6"speakers, and generally they're of higher quality than the same brand 4"×6"s. NalinMFG adapter plates will fit any standard 5.25" speaker on the market.
Don't be fooled by cheap PVC or plastic that will crack in cold weather with age, do it right the first time with 16g CNC Laser Cut CR1018 Steel! 100% Made in USA
With your order you receive two (2) adapter plates(driver & passenger), (8) #8 machine bolts, and (8) #8 machine nuts. Shipped raw steel. SPEAKERS NOT INCLUDED.
NOTE: This modification will require you cut metal inside your dash. Exercise
caution, use appropriate safety equipment, and take the time to read a "How
To" write-up before taking on this project.
