Wslm, apa nama amp tu? Masalah panas ni biasanya kalau bridged, kipas mati, cooling sys tdk efisyen, tmpt pemasangan tdk sesuai, cara pemasangan terbalik, run 2 ohm - 1 ohm load, etc...cuba cek dulu satu2 , ada suis2 lain di amp tu? Saya ada amp old school kalau pasang lama memang panas gila juga, tp tiada masalah sbb memang di buat gitu

RMS ni susa kira.sbb dia teda formula yg tetap.ada amp yg RMS 1/4 dari max.ada yg 1/2 dan lain2.

"run 2ohm or 1ohm" ini klau sub double voice coil.4ohm bleh jadi 8 or 2 ohm. jdi klau 2ohm amp yg tdk support gitu rendah akan panas.

amp ada protection protect mode ka klau panas? klau teda bhaya juga tu.klau telampau panas dia trus rosak.

kadang2, bila gain kena up terus panas sbb itu la max power itu amp boleh supply.gain bukan volume. bila preamp sub vol suda half, gain sikit sja bleh naik. voltage signal preamp suda besar. so amplification pun besar la.so terjadi la distortion/clipping

satu sbb lgi, mungkin itu la max kekuatan sub tu. maksudnya bila mau push lgi kasi kuat, akan terjadi distortion/clipping. tpi sub ni susa sikit dngar bunyi distortion tau clipping.tu yg bhaya.

cuba test skrg ni gain sub paling min, kasi full vol sub d preamp. amp panas tau tdk?
