I'm old and lazy to look through this entire section.
I did look at the thread on using OEM wiring to Alpine ktp444u amp.
Looking to upgrade just OEM door speakers. I know they're run via stock amp in trunk. I'm willing to buy a mini amp to run new speakers. I won't be installing this on my own. Probably go to a reputable car audio shop. I wanna be prepared before I go there knowing prices and so forth.
Budget for just speakers and amp, $250-$350. Not sure if I should go component 6.5 speakers or just Two or three way 6.5.
Thanks for the suggestions in advance. I appreciate it.
