I've searched around and I know how to install speakers and amp but here's my stall point. I have a 2008 G37 coupe non bose and I'm adding 2 10' subs in the rear and I replaced the doors and rear panel 6x9s. I have a punch mono amp for the subs and a punch 2 channel for the door and panel speakers. I have a regular PAC converter and I also have a 3sixty line driver/converter and for the life of me can't find out what converter to use on what amp for the best result. One guy at a local audio shop said use the 3sixty in the highs and then another installer came up and said no put it on the subs. I'm clueless and any opinions would be really appreciated. Thanks

 

I would use the 3sixty on the fronts. I think it would produce better sound.
