What's up guys. Just got back into car audio for the past year after a 10 year absence. My first build back was 2 SQ hds315s on a AQ3500, it got down but just wasn't enough after I got used to the bass again. I'm now acquiring gear to start a wall build in my truck, I'm ready to get loud!!! Boy this is an expensive hobby. Let's see some of your current builds. Cheers from Chicago!
