Upon unboxing seems to be a good quality head unit, heavy and sturdy feeling unlike your average box store unit. Installed four days ago spent about 3 hours fine tuning everything and I'm very impressed with the overall improvement of sound quality, tuning abilities this head unit opens up, and just the amount of true power this puts out. Not a quick install to do it right tho, I ran two12 agw fused at 30 amps from aux battery to head unit as well as two 12 agw grounds from aux battery to head unit as well as all 12 agw ofc speaker wire from head unit to all speakers. Worth the time invested to do it right sound quality is amazing now. DS18 did a phenomenal job with this head unit as of now 4 days in I would recommend this to anyone looking for more power and tuning abilities without full on gutting their car and adding a DSP and an additional amp for their mid range speakers.
