    Well it depends on the design and how hard you are driving it but if you can still touch it for more than a few seconds then it is probably fine.

    Thanks,
    I have a polk sub model psw12 and denon 2307 receiver and do drive it a bit heavy at times. I had to send my amp to polk for repair and when I removed it from the sub case the insulation around the input for the lfe unfiltered input had melted all around the circuits. They replaced the amp and I got it back today and installed in and gave it a go and got a very hot panel on the back of amp. I removed it from the sub and it looks like the insulation is beginning to melt again. I have my receiver set to yes on the subwoofer and it gives me an option for LFE or LFE + Main. I use the Lfe option and have the frequency level set to 80. I use a single coaxial sub cable from the sub out on my receiver to and this is where I am a bit confused...there are two connections for line levels in on my sub one is yellow and sais unfiltered and the other is dual a red and white that sais line in filtered. If the insulation around the unfiltered input is melting should I be using one of the filtered inputs on the sub.

    Sorry but I'm a novice at this and learning as I go.
    PSW 12 sub
    Denon 2307 ci receiver
    4 6" polk bookshelfs
    1 125 watt polk center channel
    14 gauge wiring
    The insulation around my coaxial lfe inputs seems to be melting. Do I need to get a better sub or am I pushing the levels a bit much?

    Thanks

    nothing should be melting.. if it is.. turn it off and call Polk Audio customer service.. you don't want to toast that subwoofer and you really don't want to start a fire either..
