ok well i just blew my p2's and i am thinking about buying p3's. how can i set my amp so that i dont blow them? i have a rockford fosgate p8002 amp. it has a gain knob and a FREQ. knob that goes from 40-400 Hz.
This is doen to the installer. I would keep my fain on at 2pm However you would turn the stereo on push it to the maximium. Turn amp on turn gain on maximum. Reduce till the distortion is no longer heard. Thsi is the norm when setting up amps.
Right. First of all, your amp will kick out 800wrms at 4ohms bridged. Two 2ohm DVC subs are not going to show your amp the correct load. You can run one of those subs fine (provided you set the system up correctly, the sub will probably enjoy the extra power). If you want two subs, you need Dual 4ohm coils.
With respect to gains, GET IT SCOPED. I originally set my system up with a multimeter and when I scoped it about a week later I'd still managed to set it up a little 'hot'. Also, you should scope your head units outputs as not many will run at full tilt without clipping.
