Dont know what to do to amp my rear deck speakers, new to audio, need a little assist

[aives245]

So i have two kicker KS693 6x9's in my rear deck, and when i turn the volume up moderatly loud the mids and treble starts to distort pretty badly, so i was thinking that powering with an amp would possibly help that right?..but regardless i want to get an amp anyways cuz i want to get some new 6.5 for my doors and power all 4 speakers in my car.. any opinions?

Each speaker has a max of 300 watts, and peak rms of 100, if that means anything..but it shouldnt distort if its only being powered by a head unit shouldnt it?

[>>SQL<<]

most headunits (all cheaper ones) have very small underpowered amps inside of them and distort badly when turned up loud.
A decent 4 channel amp like a MB Quart would help much.

what wattage amp would you suggest to power just the rear deck speakers too there full potential

[Bettr n' Revrse]

Whats the RMS on them? However without getting into that you shouldnt be concentrating on your rear deck anyway but more your frontstage... Those Kickers arent really worth power anyway IMO

The RMS peak handling is 100, max watts is 300

Fore the 6x9's
