I'm about to update my sound system on my new Koup, did the same on my Forte Sedan but sold that.. The first thing I'm going to do is Dynamat the doors and the rear speaker enclosures, I hope the Dynamat door kit is enough to do this.
On the sedan I installed a 4 channel power Amp I hooked this up by splicing into the speaker wires, it was a bit messy so i was wondering is there a better way of connecting to the head unit.
Also I was wondering what the stock speakers sound like with a decent power amp installed, I noticed on the Forte Sedan the speakers were rated at 22w.
