Just got my 2500d in and sound is low and distorted from my single 15" fi btl. I tried to hook up the rca's differently but is still very low even if the volume on the headunit is turned up quite a bit. What could be the problem?
How do you have your gains set on the amp? Maybe your rcas are bad or going bad? Is your box big enough for the woofer? I'm assuming you've checked all your HU settings.
