I have it on two Deaf Bonce 15's rated at 1500wrms, and I'm pretty happy with it. I bought a two-year warranty for it through squaretrade, but no problems yet. I did have to add a fan under the seat to keep it out of thermal shutdown when i run it hard for a while. I think it would prefer another run of 1/0.I sold my XTR2500 before I installed it. What are you running off of it. I have an AB HD15 that I was going to run off of it. Is it the beast that I thought it was? My electrical is limited on my 55 year old car. So, I sold it to het an MD3K.
