I have removed the standard rear speakers and put in the 160W 6x9's yesterday and I will put the 6.5" Splits in the front when I have time, I am going to put the amp under the passenger seat and a 12" sub behind the passenger seat. Will the amp be able to run: the 6.5" splits in front the 6x9's in rear and the sub ???? My sub is 300 WRMS so it would be 600W max. if this all goes to plan my ute will just pump the sound out.
