Gunz That Turn on Nunz
one pair of 2 volt preouts is not nice. Thats limiting his performance of his whole system. I actually highly doubt its a true 2 volt preout as well because its one of those rear/sub interchangeable sub outs and every experience with those literally limits more than half of the actual potential output of the system by far. Bass literally improved two fold with a head unit swap to a proper 4 volt pre out with dedicated sub out. Definitely one of the weak links in his setup, possibly the weakest.At least you have a nice head unit......
OP wire one sub out of phase like mentioned before. Make sure you have proper wire gauge power and ground for your amp. Specs say your amp is .500 mv to 6 volts meaning your head unit volume and sub level needs to be pretty high up along with the amp gains in order to get anything out of that amp, your preout signal is way too weak IMO. But definitely check the phase first. Make sure your head unit its selected for subwoofer pre-out in the audio options.
