I have 2 300 amp alts 4 runs pos 4runs neg of 2/0 gage 4 d3100s and I had 2 of the 1 amps and they both sucked ! My soundstream 10k was way louder direct swap and the 10k is only a 4k amp on 12.4 volt

I had this amp for about 6months and was very disappointed ! My soundstream 10k was a lot louder detect swap ! And so was my pg elite 1 direct swap ! I now have 2 elite 1s strapped at 1ohm and I'm very impressed ! I love the elite amps
