Phoenix Gold Phorum

I have a lot of parts from my older vehicles. I just bought a new 2014 Honda Accord 4 dr and the system sucks. I am going to use the stock deck with a processor.
I only have room for front door speakers and tweeters and rear deck speakers. I want to keep my trunk room and fold down the rear seats if possible. Will buy a set of 6.5 focal componets.

I have laying around:

AMPS
1 PG ZX450
1 PG Xenon 4.200
1 Alpine mrf 540
1 Soundstream 300sx

SPEAKERS
Diamond Audio Hex 6.5 componets
2 Soundstream SPL 10's
1 Soundstream SPL 12

Is the Zx450 a better amp than the Xenon 4.200
the Apine 540 seems to small at 50 watts @12v and 80 watts @ 14.4 birth sheet says 83 watts
Should I sell all the parts and start new or will some of these old parts do the job.
i want it loud and clear. dont know about clipping and ohms just want to best for the money

do you mean xenon x200.4 they never made that unit 4.200?
if it is the x200.4 is a great amp 200x4 the zx450 need caps changed but will only do 1/2 that

those hex componants are some of the sweetest speakers I have heard.
