I have recently purchased a 2003 Accord Coupe EX V6 non-navi. I started out by replacing the stock 6 1/2's and 6x9's with higher quality Alpine speakers. These speakers are much clearer and hit the mids and highs quite well but still don't have quite the bass punch I'm looking for, and I would like to hook up a wiring kit and install an amplifiar/subwoofer if possible. I am new to this so my question will be, with the stock head unit will I be able to wire this vehicle up for an aftermarket amplifiar/subwoofer because replacing the head unit would be expensive and a procedure I would prefer not to do. Hopefully someone with experience in this will see this post and be able to tell me if my system is compatible to be wired up for a Sound System.
