If anyone has the same question in mind. I would suggest the memphis cm cast. unless you have a way of rebuilding the orion hcca's yourself be prepared to send them away if anything goes wrong. i know now with memphis you can just get a recone kit or whatever you need to rebuild it. i did my research and memphis seemed like a better choice.
Well my heart has always been with Orion back in the late 80's. I have still subs from back then working flawlessly, but those were still made in the USA, not know about now.
I still have 2 X 2100HCCA, 2X225HCCA, 200CRX, and a bunch of other stuff.
Was thinking of 2 X 225HCCA for the corrado
