Hey there,
Got my roadster almost a month ago and I'm seriously in love. Spent all my savings on it. It's a 06' touring, great condition, and packs some serious power.
Right now it has a stage 2 stillen sc, with a aem intake (3"), full magnaflow exhaust, stage 2 clutch etc... She came with a custom sound system, hence I cant use the trunk.
Ok, I'm pretty sure most of you are confused as to what my question is hahaha.
I really want to sell the amps, subs, and the custom molding they're in. Secondly is it possible to remove the convertible unite, i.e keep the rag top, but remove the system ? (reduce weight)
It's my first z, so how would you guys get this project started ?

Thanks guys
