How would the car audio composition sound?

Question

I recently purchased the following for my Mazda 323 Astina

- BOSE CAR SPEAKERS 6.5"/8.5" Rear speakers (unknown specs) - which I am planning to sell so consider this out.....

- Sony CDX-S2210S Xplod 55w x4 (currently using on my car)

- Alpine SPS-400 Type S 4" Coaxial Car Speakers 340W

- Alpine SPS-609 Type S 6x9" 3 Way Speakers 520W

- ALPINE PDX-5 5 CHANNEL CAR AUDIO AMPLIFIER

- 12'' Sony Xplod 1200w

Just wondering how would this sound in clearity and quality compared to the composition I had before (as below)

- Sony CDX-S2210S Xplod 55w x4

- 12'' Sony Xplod 1200w

- Sony Xplod 300w stereo amp

- Sony Xplod 2 way front speakers

- Pioneer 2/3 way rear speakers

Thanks a million to all who give their honest opinion

Answer 1

it wont be much louder, but the sound quality will be a lot better

i would suggest some 2 or 3 ways for the front also to get the high notes or some tweeters
