Ok so I am not new to car audio but I am somewhat new to high power car audio and I have a question.
147db in an 06 eclipse
3x optima yellow tops
2x 1/0 along with a big three
stock 110a alt,(soon to be 240a)
Sundown zv.4 rev2 15" 1ohm (2000 rms)
ts3.5k (5k uncertified)
5 cubicft box with dual 6" aero ports
My question is this, I tuned my system with an oscilloscope, the voltage reached the max of my oscilloscope with ought any clipping that I could see, I do not remember the voltage but when multiplied by my clamp meter results I got around 1200 watts that sounded fine so I left it. The problem is that any time I play one of my slightly louder songs for more than maybe a minute I do get a very small and sudden smell of what I believe to be burning voice coil. when this happens it is not much louder than the song I used to tune the system and my car voltage is only dropped down to about 13.7. Even if I was clipping though, clipping at roughly 1500 watts shouldn't even happen with a system voltage of 13.7 let alone burn a voice coil of a sub that is known to be run on 3000+ right? I heard somebody once say that their sa-15 gets smelly when they play it but it just doesn't seem right.
I just feel like I am missing something or maybe just don't have much experience with higher power CA.
Hello everyone, long time no see. I am selling a pair of Dual 2-ohm (technically D1.7) 12" Sundown X v.2's built by Dave Leib a.k.a "Strongman Designs."
Reason I am selling them is because I realized upon testing to see if my digital multi-meter was working correctly that one of the coils is reading higher on the one sub indicating that too much heat had been applied to it recently so rather than risking any further damage to it I am going to assume that I have too much power for these.
Having said this in all honesty, let me make it perfectly clear here that both subs are still in perfect working order as we speak, even the one that is reading differently. Had I not thrown my multi-meter on it to test it in order to see if it was working properly (the multi-meter itself) I would have never known there was any difference or discrepancy between the two.
However, because one of them is reading off now and I do not know what is to be expected out of it's performance long-term I will be letting these go for $500+ shipping (that includes both).
Any further questions or concerns please feel free to text me at 440-915-2309
