Installing loudspeakers at the front in a Beetle is a real disaster, in the door panels there is no room and behind the grill next to the km counter doesn't give a great stereo sound.
But there is a solution, speaker plates that are mounted left and right under the dashboard against the innner wing where the loudspeakers can be built in.
The panels will give you enough space for speakers with a diameter of up to 6.5 inches (16.51 cm).
These are nicely finished, with a grain motif and black in color, off course they can be sprayed any color you would like by using the right materials. It is only a matter of cutting the holes and mounting your loudspeakers by securing them with parkers (not included).
