That was one of the reasons I asked. I use to have a couple of SS in my truck in the early 90's and loved them. When they came out with the reference amps, I was looking for a reason to get a set. But now I am rethinking it.I'd try and find some old school American made Soundstream if you want quality
I noticed that, 21" long for a 100 x4 is pretty big.I would run the new reference line, they were designed by Griz Archer like the old school ones. Only thing I have agenst them is the size they are rather large.
Too expensive. Tried & true amps can be had for the same money...I would run the new reference line
