Is my stuff good enough to compete with??

Hey everyone, ths my firdt post and I wanted to start out with a question. I just spent a couple grand on a sound system and alarm, and I was woundering if it was good enough to compete with. I have:

JVC SH99 Head unit
6.5 Pioneer premiere speakers
6x9 Pioneer Premiere speakers
Cadence tweeters
12" Cadence beast Subwoofer
Z7000 Cadence amp
Q4000 Cadence amp

Do I have a shot, and is there a web site that could tell me how to get the most out of my system?
