i have recently installed a subwoofer in my car, its a hertz hx250 d wich delivers 450Wrms in 2 ohm. It is driven by a Audison SR 1D mono amplifier wich delivers 460 wrms in 2 ohm. i just discovered that adjusting this shit was easier said than dine. So i wonder if anyone might help me along with tips and advises. Kay.
