I have a 2015 jeep grand Cherokee with the Alpine 506 watt 9 speaker system. It's pretty sub part sojnding. The front doors are 6x9's, rear doors are 6.5's1 in tweets in the A pillars, and a 3.5 center. It has 8in sub and 2 2.5 int rrar pillars (not worried about them). The factory amp has a 30 amp fuse and loons large enough that it could be pushing 500 rms. The doors and sub are 2 ohm.
My question is I'm looking for decent speakers to swap. I have some PHD AF1.CTW'S that I really like. My question is I do try to pick up some (1)used Focal K2 woofers off eBay and use adapter for the 6x9 hole in the front doors possible get a set and use the tweets . (2)used K2 in the rear doors focal coaxial 6x9 (3) cdt ES woofers. On the Jeep forums everyone recommends focal 165's and a Polk 3.5 coaxial center makes a huge difference. I'm open to suggestions. I'm mostly looking for a clean sound. I want to stick to an efficient 90+dB sensitive and 2 ohm speaker. I would prefer to use a 6x9 up front for the added cone area. The sub is pretty weak. the 3.5 is 4ohm and pretty much a full range speaker. I have read conflicting specs on the doors being crossed over at 2500hz to them being full range once over half volume.
Once I see how this works somebody posted about replacing and fiberglass in a helix 10in sub in the factory box with good results. I'm not looking for a stopper just something that sounds good. I'm much more Sq driven then loud. Thanks
