us amps xt 4000d which Ive found for $275 or the saz1500d for $600.i am leaning more to the 1500d because si recommends them for the mag(the sub i want).if i ran 1 mag at 1 ohm both amp would give me 1500w. my ? is what would be better or would they be the same.is the saz a better built amp as far as not breaking.right now i have 2 amps a ed nine1 and jl 500/1. i blew my ed amp at 2ohms and i have blown it twice in the last 6mo. i have never blown my jl amp even when i purposly hooked it up at .5 ohm when it can only handle 1.5 to 4 i couldnt break it. i have had the jl for 5 yrs. my main ? is will the saz hold up like my jl. i would rather pay more for the same watts for an amp that wont break.
