distibution block & crossover?
 

Vehicle: 2008 Ford Fusion 2.3 4cyl
Unit: Boss BV960NV
Amp: 1x Alpine MRV-F300
Speakers: 4x Rockford Fosgate Prime R168X2
Accessories: Rockford Fosgate RFK8i

1. Trying to find out if I need a distribution block?

2. Forgot I had tweeters, do I still need a crossover for the front speakers and tweeters?

3. Will the crossover divide power between the front speakers and tweeters?

Thank you for the help!

Crossover doesn't necessarily divide power but frequency. so if you have a 50watt rated woofer and a 50 watt rated tweeter you do not need 100 watts to run them.
Yes especially for tweeters you DO need a crossover that can be as simple at an inline non-polarized electrolitic capacitor or an aftermarket 12db/octave crossover board.
Also you'll have to be more specific about the distro block, where do you think you need one?

Thank you for your response. Instruction manual said that if cable it longer than 6 ft, I would need a distribution block. But I am reading that the Dist.Block is only used if using 2 amps?

That is correct, a distro block is used to distribute power from one wire to multiple points. For example if you need to power a sub amp and a 4ch amp then you could have 1 run of 1/0 wire coming from under the hood into a distribusion block that has 2x 4gauge outputs to power 2x amps. You could also use it to extend a cable that is too short to reach your amps but there is no other reason to use one really.
