Any tips on how to run the wires from the A-piller and where did you put the Crossover box?

Thanks

My crossover boxes are under the front seats. As for the tweeter my tweeters fit in the factory locations. For the wiring I used the factory wire from the factory tweeter and spliced it at the radio and ran it to my crossovers. It wasn't too bad, the hardest part was getting new wires to speakers in the door.

i took the plastic A-pillar panel off and ran the wire down behind that. My cross overs are mouted on the amp rack in the cargo area. It's built into the driver's side wall in the back.
