I recently came across 3 10" MTX Blue Thunders. They are in a sealed box, problem is that I feel that I am not getting the most out of them, but I don't know anything about the speakers. From what I have read they are 12 ohms, and when wired together they are 4 ohm. About this, they are just all wired to one terminal from the negative and positive of each ones, is this right? Secondly they are supposed to be 75 - 250 RMS and 400 Peak, I have a 1600 Interfire Monoblock pushing them, I don't have the amp tuned up all the way because I am fearing pushing the subs too much due to not knowing their background. I do have a box that is vented for 2 10"s and I was wondering if maybe i should just push 2 in the vented box, or what I should do. Thank you!
