Trying to figure out which upgrades I should do?

[GassenD]

Went to my first competition this weekend, and placed 2nd in my division with a 145 on music so I was pretty excited (Not all that big but for my first install I'm happy)

I'm trying to figured out what I could do to get a little bit of a higher number before my next comp in August..

I'm definitely going to need to dampen my back hatch and panels in my explorer, just not sure really where to even start. Is there any good stuff that just peel and sticks or should I go with the stuff you actually have to apply the adhesive and roll it on?

Also, would upgrading my Head unit be that much better? It's a JVC KDR300, I've had it for about 5 years and I've read that getting a better HU could make it a world of difference...
