well most stores are SUPPOSE to take precautions. but ok...not them. haha the most important thing when installing components is the place of the crossover and the spkr wires. Before u disconnect switches and remove the door panel, wut u want to do is roll down the window. That way when placing the crossover, you have a good idea of where not to put it. In regards to the spkr wiring, you might want to tape it down to the chasis of the door or something. Test it out cuz u don't wanna end up like vthondaboi.
