New Sony Headunit + AMP?

[Atreyix]

Hello all,

I have a Saturn LS2, It Has 6 1/2's in the front doors, and 5 1/4's in the rear doors. The speakers were blown when i bought the car so I put in some Pioneer speakers, 6 1/2's (LINK IS HERE) which can be pushed too 40 RMS, and 5 1/4's which can be pushed to 35 RMS(LINK IS HERE). I also put in a Kenwood KDC-255U Head unit in, Which pushes 22 RMS each channel. (LINK IS HERE)

Now my question, If I put in (THIS) Sony head unit, which has a built in AMP of 40 RMS. Would I see a difference? Is 22 vs 40 RMS a pretty big difference or a smaller difference?

You don't have 22 now. It's closer to 12. Every time you double power on paper it's a 3db gain. 3db is the point anyone can tell there is a increase in output. So you could gain 6db. That's a good bit. But you are better of getting a real amp.
