Hey everyone. I've been around car audio for about 5 years but am by no means an expert. I'm here to learn and y'all have already taught me a lot. I'm in the process of designing a new system for my '99 4dr Tahoe. So far I have a DC lvl 4 15" and ordered some 1/0 KLMX power wire today. For a headunit I'm leaning towards an Eclipse cd5030 and for an amp either a AQ1200d or a Sundown 1200d. My job currently has me in CA now so I plan on ordering everything I want so I can do everything all at once. I'm glad to be a part of ca.com.
