I installed all last years model of Pioneer Premiere products from Sonic for $650, 1 DIN CD head unit, 5.25 Coaxials in the kick panels rather than anticipate door slamming and moisture from the doors, 6 x 9's in the rear deck from the bottom with a mesh cover shelf so as not to see the ugly speaker covers 2 10" subs in a speaker box on the back shelf in the trunk along with 2200 watts from 3 amps. Ran off the regular battery with 110 amp alternator. Hired a stereo guy to hook it all up for $50. Sounds great and don't need it past half volume. Turned out so I have done 3 more for cust.
