check clearances on both sides of the planned
mounting surface. Also check for any potential
obstacles, such as window tracks and motors,
wiring harnesses, etc. Check both sides of the
vehicle, many vehicles are not symmetrical!

Should you need grilles, you will need to purchase

excess of 100dB can cause permanent hearing
loss. These high-performance loudspeakers can
