greetings, i am looking @ a MTX Thunder4250d amp to buy but noticed it only shows a range of 40hz - 200hz. I want this to drive a sealed 4512-44 wired in parallel, but should i look for something that starts @ 20hz or will this produce the same lows as what i am using now. btw i am using a little rtp202 (150watts rms) to push this sub now which i will probably use as a front driver once i find an approprate sub amp just wondering what would be a good driver for this sub, & maybe if i should port it or not... thx all, greatly appreciate the advice dz67
it shows a crossover range at 40hz-200hz... that doesn't mean it won't play low. I know my nine.1's crossover starts a 50hz. Usually people don't crossover that low anyway. what is your sub crossed over to now anyway? I have my sub crossed over at 80hz
