Okay so tonight I removed my old 800 watt amplifier and installed my new 1400 watt hifonics amp. I had the 800 watt amp installed by a professional installation company so I figured all the wiring would already be there. Because of the increase in power, I upgraded the power wire and ground wire from 8 gauge to 4 gauge wiring. Other then that, I kept the RCA's, speaker wires, and remote cable the installation company put in.
So I wired it all in and when I turned my car on, the amp powers up, but their is no output from the subwoofers? I've tried plugging in my RCA's in multiple different patterns and testing but no luck. I heard somewhere the ground connection may be strong enough to keep the amp power up but not enough to make the subs hit, does that make any sense?
Any suggestions guys?
