I’m fucking jealous. I’d love to collect some old car stereo crap. They don’t make that shit like they used to.
It’s pretty much all for sale other than the stroker 15.
Haha - indeed, sir- I had a 250SX and a 225HCCA waay back, running Orion XTR’s and MB Quart separates. I never should have gotten rid of them. 
They are worth every penny.
Some of it yes. (2) of the amps came from Extreme Sounds which has been out of business for years. I might have gotten the components there though. Components and deck were from Alpha of course. The subs were from my friend, he had (12) 12W6 in his Pontiac Transport. He had the loudest systems in this area since the early 90’s. He did the install on the 93 GT for me too other than I did all the wiring etc.
My friend has a few 225 HCCA and 250 HCCA if he decides to sell I will post them up here. Also has some Orion XTR Pro 15’s
Good deal for this amp…!
Ahhh…miss old school car audio!
Had an hcca 275g4 for a short period of time, some of the old white zapco ag series, ect
