2nd Generation Alpine 6 Speaker Upgrade Questions
Overall, I'm disappointed with the "Premium" 6 speaker system. I didn't pay a lot of attention to it when I bought the car but now I'm noticing some poor performance. I saw "Premium" on the window sticker but didn't do my due diligence and really investigate what that means. Apparently, I have the base Alpine 6 speaker system. In looking what I can do with it to improve performance, here's what I've found. Please correct any wrongs for me, any and all help is appreciated.
1.) Simple fix: Replace the front door 6x9s, the dash 3.5"s, and the rear 6x9s with the Mopar Kicker upgrades. From what I've read, that is a decent improvement. My problem is that I suspect it won't yield the bass I'm after. I hate to just throw money away and don't see these upgrades being much better than what's in there.
2.) Complicated fix: I see PAC makes a device that shims in between the head unit and the amp. Part number is C2A-CHY5. Basically it gives you line level outputs and pays attention to the CAN messages destined for the amp to give you volume control. If I understand correctly, I could us this and go out to my own amp. At that point I could choose to just power a subwoofer and amp or I could run all new wires to all the speaker locations and add additional amp(s) to power these locations.
The questions that I've come up with are in regards to the "Complicated fix".
A.) If I understand correctly, the factory alpine amp has built in crossovers and sends midbass to the front 6x9s, mids and highs, to the front dash 3.5", and full range to the rear 6x9s. Is this correct? Is it also correct that this system is "smart" and the louder it goes the more it throttles down the bass to the entire system? Hence the need for the C2A-CHY5 instead of a Line Out Converter just added to the rear 6x9s. Right?
B.) If I choose to eliminate the use of the factory amp, I understand that I need to leave it plugged in, in order to retain the CAN signaling. If I run all new speakers and all new wire and run that from my own aftermarket amps, will I retain all the Nav, Parking Assist, and Safeytec warning noises that come through the audio system? I've noticed the parking assist is speaker specific. ie. if the obstruction is near the front right of the car, the warning signal comes out of that front right speaker. Will this ability be maintained when using the PAC C2A-CHY5?
One final thought was to swap the amp out with one of the better Alpine amps but I've read the wiring harnesses are not in the car. Anyone know if that's a fact? I thought about maybe just adding the sub to the rear Deck and doing the Mopar upgrades but I'm not sure which Amp to get and if the wiring is all there or not. Any help in this area would also be appreciated.
