I recently bought a system. I looked around for awhile until I came across an installer that mostly did Memphis car audio. He also sold street edge. He told me that street edge was a memphis audio line. The installer was good, well informed. I got more information out of him then I could out of any bestbuy/circut city lackey. I'm new to the whole sound system thing. I just wanted something to compliment my bose system in my Altima SE. It isn't the powerful knock out line like memphis, but it is more balanced for a good sound system. Or so I'm told.
You won't find anything online. And if it's a memphis line then it will only be sold by authorized dealers.
