opinions on old school amps

I was thinking of going with some older series amplifiers for my 07 Ion3 and was wanting to see what ppl think about the older brands of the early to mid 1990's. I remember many of them and had enjoyed them very much back in the day. Soundstream Reference series, HiFonics series VIII, the old Rockfords that were oval shaped and black... those are a few that I was thinking of. Targa was another brand that I just thought of...

Also, I was wondering if anyone had any opinions on a company called Alphasonik. I remember this company back in the late 80's when I was a boy looking through Crutchfield and learning about stuff. I searched for the brand tonight and was surprised to not only find a website but also find a variety of what appears to be pretty good amps.

Thanks ahead of time.

I was thinking of those soundstream reference amps mentioned above. In regard to the 705, is it 2ohm or 1ohm stable mono and does anyone know what the output would be (in other words, would I need one to push both of the G5 DVC 4ohm 10's I have @ 1ohm or would I need two of them, one for each ten @ 2ohms each)?

I looked at some pics last night of the Orions and it brought back some memories and Haemphyst, I've heard of ppl running them that low years ago. They are some powerful amps. My reluctance is how big they are. The amp rack I am thinking of doing is going to be on the underside of the rear deck with the amps facing down. So, I dont know if those amps would put like that would make them sit too low into the trunk, making them more of an obstacle in the trunk than anything else.

What about the HiFonics series? The last ones I liked were the Series VIII and I thought someone bought them out after that... maybe around 1996 or 97? And after that happened, the quality went down a few notches. The same thing happened to Autotek (remember the "Mean Machine Bass Thrust" amps? The ole Autotek44?) if I'm not mistaken. PPI too went through this round 1999? I was thinking of the HF Isis. I had a friend back in 1994-95 who had one of these jewels on two Pioneer "IMPP" 12s wired at 2ohms... the thing pounded. We had the 12's in a sealed box in a half camper shell on an S10.
