I never thought I'd see the day but yesterday... one of my IDmax's crapped the bed.
Who'd of thunk that 1560 wRms would kill a 1000 watt sub? *eyes go back and forth like "not me" *.
Actually that's not even true... the other one is taking 1480 very happily... and like I said, they're only RATED at 1000. Hell of a sub.
Problem w/ the one that went is it was one of a few (i think 16?) that had a non compliant surround... less excursion than the cone was capable of and much much stiffer.
I'm guessing that the surround not "mixing well" with the rest of hte speaker's components caused it to be less able to deal with my driving it well beyond its rated limits. And so -- it **** the bed.
3 days of work to get it out and put a new one in --- i'm not looking forward to that.
thank god for warranty.
However, on a GOOOOOOOOOD note.... I got a free amp.
My buddy gave me an old Mtx Blue Thunder 754... his boss had been using it for years and then it just kept blowing fuses and shutting off and no one could fix it -- so... it was relegated to me.
third channel was completely blown shut and two caps in the power supply had burst.
I've got two mostfets, two capacitors, and a coil coming in the mail from digikey -- me thinks that after that, she'll run like new.
I repainted the case in its factory color (7 years kind of takes a toll on an amps cosmetics). and she looks fantastic.
So i think my whole "i wnat a better amp for my fronts" dillema is solved... for free (well 5 bucks for parts + 6 shipping + a 5 dollar small order fee)... 150 x 2 at 4 ohms bridged w/ 0.3% thd or better at 12.5 V -- 280 x 2 at 14.4 (small power supply -- this amp is almost identical to the 6304 in design- even tho its pre-surface mount tech-, but the small ass power supply leads to a lower P rating for bridged mode).
I like these old amps with the push through boards... they're a lot easier to work on.
check it out.... http://www.mtx.com/caraudio/archive/thunder4300x.cfm
the blue thunder standard series was the same board as this 4300X -- only its got a dark navy blue case with heat sink ribbing in the middle.
anywho -- thats my long winded stupidity for the day.
