Hello i am currently going to change my speakers in my 4runner 2000, long time ago i changed the stereo to a phase linear cd1211 cd Receiver and noticed that it handles only 13 watts RMS X 4 speakers, i wanted to change the front door speakers and buy a pair of JBL 6.5" 3-way speakers that handle 60watts RMS each, whats are my options? would i be fine if i just install the speakers or do i need a new stereo or perhaps a amplifier???
