You want to give your speakers adequate power. The speakers you are talking about will play with no matter what power you give them. However, the more power you give them, the better and more full they will sound.

Tha Alpine deck is listed as 60x4 max power. The RMS power (actual continuos power) will actually be closer to the 25-30 watts.

You'll still be underpowering them either way.

Is it possible for you to go to a shop that has what you want and listen to each set of speakers being powered by an Alpine deck??? That would determine which set sounds better... :thumbup:
