Component speakers in dash w/ Stock tweeter

2015 JKU 1430 Base Audio:

Think of putting some Alpine Component speakers with built in crossovers in the dash and using the stock tweeter. This way I use the stock wiring easier.

Now does the JKU have a crossover built it? If so, just get component speakers without a built in crossover and really one the Jeeps crossover?

Have the KICKER upgrade in now and want to eliminate the double tweeter situation.

Will keep the KICKER Upgrade in sound bar and unplug the tweeters up there.
