Ok, I have a PowerAcoustic headunit, which is crap. I thought it'd be cool since it has a DSP (yeah right). I'm looking to improve the sound quality without having to replace the HU. It's got 2v preouts, and my Aura amp accepts just 2.5v inputs, the THD is rather high and SNR is low. Say I get an Equalizer with an 8v output. Does my amp's 2.5v inputs mean that the 8v on the Equalizer is downconverted? Perhaps I should replace my amp with one that accepts higher input? oh and I'm running Eclipse speakers.
