I've been to Arizona Sound for all my car stereo needs. No matter the vehicle or my budget, they worked with me to get the best bang for my buck. Their customer service gets an A+ too!
1st car was a 78' Cadillac Deville. They installed a deck[that I purchased from them] and two 12-inch Sony Subs I had bought off craigslist. They had it ready to rock in NO TIME.
2nd car was a 02' Impala. They installed a Sony Deck with Sony Door speakers and two JVC subs.
3rd Car 08' mustang GT. Installed two 10' Kicker 250 Comp Subs
4th Car 96' Mustang GT. JVC Flip down monitor and 2 10-inch Subs
5th Car 10' Mustang GT. Installed one 12-inch Kicker Sub
I've went to them each time and have yet to be dissatisfied.
DEF receommend them.
