Getting system install need to know something

[greekthang]

Hello guys,

I though I would do a little upgrade to my stock system this is what I am doing:

- Alpine IVA-D310 7" Wide DVD/MP3 Receiver DVD

- Focal 130V2 components front end

- 2 8" subs that replace the stock speaker in the rear

- Phoniex Gold 4 channel amp 600.4

I was wondering if anyone has a similar set up and what can I expect with souond quality and bass.

Thanks
