My brother in law is selling is Orion amp with 10" Orion sub in bandpass box for around 800$. The amp alone is worth 1200$ new and everything is like new. Let me know if your interested. I think he's willing to go down to 700$ but not sure
PM me with what you're looking for... how much you're willing to spend or how much power you need... or what you're planning on pushing with it.
I'll give you a price you'll love and a few options... look forward to hearing from you.
