Thanks for clearing up some things for me!
mmm well the place that was going to install it was going to put a storage place under it with a little door to cover it so it looks more flush. hmmm when i went down to the stores around my area they didnt sell double dims and if they did they where the ones that we're the nav and touch screen and such . But is sony not such a good maker for car audio? ive read around about this stuff and get mixed reviews.
hmm well my hl isent the jbl one so thats one less thing to worry about finding.

I was reading on pioneers website last night and they mentioned different types of speakers (type A, Type G , Type D) and then they had differnet amp types (type A, Type AB , Type D) If i got new speakers would i really need an amp? If i understand how car audio works that the head unit is connected to an amp that controls two speakers or controls a sub .. although a sub might not be such a good idea by the sounds of it.
