I am looking to replace my factory front speakers with a pair of 3-way Kicker 6x9's that I have laying around. I was just wondering if I am better off powering them from the stock JBL Synthesis amp or from the new Kenwood HU. An amp is out of the question since I am pretty much broke. The Zapco 360 amp I do have will not fit under the seats due to the power seats. Not sure how many ohms the 6x9's are. Hopefully someday I can figure out how to get all my good speakers and amps in there but this is just to start for now. Thanks!
