I've been planning on doing some component upgrading lately and will make a pretty decent sized investment of time and money into it.

I don't plan on running a sub as of now, but what I'm looking for is to upgrade my tweeters, and 6.5's.. I've already swapped out the 6x9's in the back with Pioneer TS-D690R's. Other than some recommendations on which components to get I had a couple questions.

1. Is it worth running everything off a stock amp, or should I upgrade to a multi channel amp to power all my components. I usually don't listen to music over 17 on my TSX, but would like to maintain clarity when going louder.

2. If I switch out the tweeters and 6.5"s in the front should I go ahead and do the rear 6.5"s as well?

3. Which components would be idle for better cleaner sound quality and which amp and crossovers would work for an overall improvement?

4. What is the best plan for a system setup if I plan on adding a sub later down the road.

Thanks for you help guys

 

Couple more.

Is there any benefit of running 2 way 6.5"s in the front by running wires to both tweeters?

Are the crossovers that come with the component system package ideal for the speakers?
