I'm looking to install a 5-channel amp in a Hummer H3, and I want it to be invisible, or as close to that as possible. The stock Monsoon amp is packaged with the subwoofer behind a panel in back, but the Stealth Box I'm putting in takes up all of that space I believe. I'm thinking an Alpine PDX-5 under the driver's seat, but it's a tight fit, I'm not sure it's a good location. Any thoughts? Anyone done something similar?
