Running particular speakers off this amp...RMS and amp controls?

Question

I have Polk Component 6 1/2s and 6x9s (100 RMS both) running off an Alpine MRP-F450 so they are receiving about 70 RMS...When it is turned up to around 45 which is not often it doesn't sound as good...I know I can't be over powering the speakers but can I adjust the gain and those amp sound settings to make it more crisp and no distortion...Also Could I run a stronger amp something like 95 RMS or is that too powerful...I mean can the Polks handle it

Also I have it hooked up RCAs one side of car with power and remote other to eliminate any static...When no song is playing there is some static I think mostly in the tweeters...Is this bad and how can it be fixed...

Any suggestions would be much appreciated

Answer 1

its not your speakers or your amp its you head unit sending a bad (clipping) signal to you amp at that volume. you can

A. not turn it up that high

B. buy a new head unit and still have the same thing happen at a different volume

C. get a line driver that will increase the signal to your amps at a lower volume and still not turn it up to 45
