Lanzar opti7001d or 2 ss rubi2500

[Spldecendant 10+ year member]

In my current setup I have a lanzar opti7001d wired at 1ohm( rated 5100rms) I hear my amp does pretty close to rated but I'm thinking I get a decent amount of rise. My freind is offering to buy my amp for 750$ which I just paid 780$ for. I was thinking because my buddy is a ss dealer and could get me the rubi 2500's for 580$ new for both. Now with them strapped at 1 ohm( each amp seeing .5) would I be able to get more power outta these amp then my opti? Would it be worth the swap and the money savings or will I be disappointed?

do you have the electrical to supply two amps at .5?? IMO you will see less rise with the two amps but more current draw as well, and in my opinion the lanzar is a better overall product
