My crossover boxes, in my doors, are wired from the factory woofer connection and out to the woofers and tweeters. The wires for the factory tweeters are taped off an tucked away. I was wondering if there would be any benefit to wiring the factory tweeter wires into the input too. I noticed they're the same color as the woofer wires and probably split off the same connection. So it seems like I would be redundant to wire those in too.

 

No benefit, as you say they are paralleled off the main speaker leads.

If you want to hear an improvement, replace the stock speaker wire with some 16ga directly from your amp. 94

 

I thought as much. Thanks!
