I wont even go into the 'why do you have a cap' question. Obviously somebody's marketing was effective on you.

As for the tweeters, yes, you would lose the tweeters. The factory amp has a crossover circuit and feeds the tweeters. If you replace the stock amp with your alpine 4 channel amp (and I WOULD!), you'll just need to get 2 little crossover's and you'll be able to wire the tweeters from the door speakers. The Front left and Front right wire feeds will first hit the crossover which then has connections for the door AND the tweeter.

With all the other equipment you are replacing I'm not sure why you're not replacing the speakers as well. Component speakers (separate woofer and tweeter) usually come with there own prewired crossover to use. Google the 'Infinity Kappa 50.9cs' speakers for an example of what I'm describing.

Good luck!
