I checked the amp and the green light is still on also my 3004 was warmer then the 1500... and my cap is still reading fine. so I think the VC's just melted lol...

it has been confirmed the VC's were destroyed :hah: I should have my new sub next week.

you must be doing something really wrong. it's not possible to break an L7 with so little power in a typical application.

so little power? they are rated for 750rms and mine was getting 1500+ rms (I was told by someone that the 1500D pushes closer to 1800rms), Selective sound set the amp and I never touched it so I would say it was just over powered.

I was just playing around with the HPF? on my deck, I had the mids at 80 and the sub at 125 (it jumps from 80 to 125)....

well realistically you never get rated power out of an amp when it's hooked up at its lowers rated load. There is such a thing as impedance rise. So even when it's hooked up at 1 ohm, as soon as the sub starts to move the amp begins to see 2 or 3 ohm. Realisitcally that sub was getting maybe 750 watts. There is also such thing as voltage drop, which also significantly decreases amp's power output.

take a multimeter and hook it up to a sub, then push on the cone and you will see what im talking about. as soon as the coil begins to move ohms no longer stay the same. it can go up by as much as 6 times.

in a reali life application no amplifier produces it's rated power when it's hooked up at one of the rated loads. you need to hook up an amp MUCH lower than it's rated to handle to get close to full power out of it. But then of course, you run into a high risk of blowing up and voiding the warranty.

it was hooked up at 2ohms which is max on the 1500D, and when my car is running my system runs around 14v... this is why I was asked before about running at 2ohms so this wouldnt happen, but now I need the power I am addicted so I cant go back now :hah:

as for moving the cone, the L7 is now Davis's new paper weight and the VC's are fused together... :D

Father Yuli 10-18-2008 12:24 PM

if i have to take a guess that amp was really seeing 4 ohms or more. so the sub wasnt getting close to 1500 watts.

Epica-Go-Boom 10-18-2008 12:31 PM

so why would it fry? I am not being sarcastic I appreciate the input. also would it be worth upgrading to a Solo X or keep with the L7?

Father Yuli 10-18-2008 01:30 PM

distortion could have done it. could be a bad amp. who knows.

if u fry another one then try a solo x

Forget the Solo X.
