I took a 10 year hiatus from the world of car audio but just got back in in May. I was perfectly fine with my old school BB2250 (old like 2005 wish old) and some newly acquired L5s. Fast forward a couple of months and I got talked into buying some Massive Hippos and a Crescendo BC3500. Last week I got 2 RE MT 18 V2s. I have been told they're pretty good, but no real idea what they do. I just know I got a steal for these 2. If I keep them I'm gonna upgrade to a BC5500 or the RE 10k amp. Just need opinions on which way to go.
