Are you planning to stick to a pair of 12s? If so, I'd say get some zv4 12s and a Sundown 5k. You'd be pretty happy with that if everything else is already up to par (electrical and whatnot).
As for honest reviews, I love Sundown products. I've ran a lot of their gear; sae12000, saz1500, saz2000, sa12s, sa15s, e8v3s, Saz3000, sa8s, sa8v2s, zv3/x's. I've never had any issues and Jacob/Brian/Debbie were always helpful when I needed advice or customer service. Great products and even better customer service.
