that is awesome! I love car Audio. I had a z24 with two pionner 800W 12" subwoofers and 1200 watt amp, pionner 3way 6x9s in the rear, factory front speakers and 4 150W tweeters. I just installed two tweeters up by the windshield, and two tweeters in the middle.
it sounded pretty good, but my friends JL 12" kicked a lot harder than my two pionners,
I never went to any sound competition, but I wish I did just to see how loud my system really was, but I was a little intimidated by other people's stereo sound systems LOL mine would be barking like a little dog while others were growling like a beast LMAO!!!
