they are rated 1000 watts RMS total combined and 2000 watts peak combined power and I'm only giving each subwoofer a maximum of 100 to 250 watts and I was playing some bass and I started to smell it so I turned it down. the dust caps I could feel some warmth to them and I could smell it was cooking a little. they didnt smoke and still seem to work fine but i'm worried they will blow out if I turn it up again. and the amplifier was not clipping or putting any distortion.
The subwoofers were not moving a whole lot at the time. I know they can move more and not smell so I dont know if its a dead zone frequency for the box that makes the subwoofers get hot without flexing and so they get hot?
the frequency is between 25 to 35hz and they can flex way more and not overheat but i'm not sure if they are damaged or if they just need to be broken in longer first?
I am using an equalizer to balance the frequency response so the deep mid and high bass frequencies are similar volume from 30hz to 100hz since they are quite boomy at certain frequencies.
Maybe my subwoofers are just too cheap? they were 100$ from
amazon including the box. I had a look inside the box and it seemed alright but I changed the speaker terminal so they are not in parallel (my amplifier has 4 channels so I bridged two of them so each subwoofer gets a stereo signal and not mono.)
also they are rated 4 ohms each so I have them wired up to 4 ohms bridged stereo on my amplifier (1000 watt amplifier. peak. and 240-260 watts RMS bridged stereo. so around 500 watts RMS total combined power for both subwoofers?)
