Yep got the mod fan blowing the same way as the stock, blowing out the front and sucking in form the rear. I have tried it the other way and the amp gets hotter even quicker. I know with the JTR's they have a 15hz tune. This happens when I have it in the low tune which is 12hz with no hpf. I am at about 83db calibrated. I still get good output to about 8hz no probs but man when make it drop bassotronics kicks even at about -15db the amp just cries out, please no more! The main issue with my drivers is that they are Dual 1 ohms wired in series to give 2 ohms load. The impedance graph within winisd shows it running below 2 ohms between 10hz and 20hz. I know this is only a model and not wholey true in real life. In the mid (17.5hz) and high (21.5hz) tunes I don't have the same issues.
I can watch a film at very loud levels in the low tune and the amp doesn't get as hot. Its music which kills it.
Another issue may well be the fact that in winisd the optimum box size is 36 cu ft for and old FI Q18 dual 1 ohm and I have them in a 15 cu ft box so when you model a low tune in a 36 cu ft box the impedance is at about 2 ohms. I guess they just are not as efficent in a box that size.
Another reason why I want those poxy blueprint drivers running a single coil BPD-04 as 4 ohms.
Jordan, I will try it to see what happens. I guess that even with the clip limiters off the fuse would still trip if it got too hot.
