Sony is trash..he might've had good luck but the majority of others have not.
Most experts recommend Alpine..though I've never used them.
I've owned 2 Pioneer HU's in previous cars and have loved both..never a skip.
Yea, see. I personally prefer sony and pioneer over alpine, I know people that have serious issues with alpine not ejecting cd's and other bull shit like that. But sony, I've personally installed 2 (one in my car and one in my sisters), and both work flawlessly. I've also got a sony 6 disc cd changer(great, no complaints) and a 760 watt sony explod amp, and again, no complaints The high pass filter on that also is great. Most of my friends have either sony or pioneer, and no one complains about sony. I know profesional audio engineers that prefer sony, but like i said, the 7 band eq on thier nice ones is amazing. I do, however plan on replacing it with a pioneer, but that's for the 7" flipout touch screen with 5.1 dolby digital sorround(hey, i'm an audio guy, have to have that kind of stuff) For speakers, yea sony is trash, but thier head units are great. Pioneer has some of the best sounding speakers too.
