I was about to order a led undercar kit from crutchfield.com but I had a few questions..

The sides state that they are 50" and the front and back are 25".

I'm pretty sure the front and back will fit. But I was wondering from someone who has installed them on the sides how long is a safe length? Do I have to leave clearance for anything? I've never mounted them before.. from my understanding they just go into the frame of the car is that correct?

I tried searching on here for the clearance but I couldn't find anything.
