I have 2 alpine type r's, (swr-1222ds) & I have them in a ported box. Now I need an amp. Do you guys think I should get 2 alpine mrp-m500s? Or run my 2 subs at 2 ohms in parallel and get a mrp-m1000? I'm not sure if you can answer this, but if you can I'd love an answer. I'm looking for great results & hard hits. If you'd rather me use something else, I only have around $300, please suggest it though, thanks.
