Don't see a place for second battery... Truck is 2017 F150 STX 4X4
i really would like to hear and compare that speaker.
im sold on all the good praise ive been reading
i have a kenwood mobile speaker. was looking at it thinking with a little modification it would work.
I'll YT the speaker and dig around. i personally don't like a cheap sounding speaker.
@Slowmover/ what is the blue cable with that speaker in picture? Looks like other cable is possibly a standard jack plug for the back of radio. do tell
