Ok, so I made the choice to return the "throw away" Sony components... they would not give me a refund even though I never opened the box. Instead, they gave me store credit. So, I am trying to think of what I could get to aid the install. I have all the RCA cables I need. I have all the ground blocks me and three other people could use. I have fast rings, speaker gasket material, speaker wire for days and days. What could I get for a little over $90 at this shop that I am overlooking? How much sound deadening do you think I could get for $90? This place is WAY overpriced so I know I am going to get screwed. The dash kit for my car is $199 on Amazon and Ebay. They wanted to charge me $369 for the exact same kit. So.... how can I maximize my $90? Any suggestions would be great cause I am drawing a blank.
