wiring speaker tdk betul 2 mnyebabkan jumlah rintangan yg tdk betul atau rintangan (ohm) yg amp tdk boleh tampung.terlalu rendah atau terlalu tinggi.

bro, boleh terangkan ka dan kalau boleh bagi penyelesaian dia, sebab aku mengalami masalah yang sama, dalam masa 5 minit amp aku boleh panas yang amat, kekadang rasa macam boleh masak telur ja, sedangkan aku guna sub yang kecil sahaja

spesifikasi sub cuma
100w 4ohm

tapi macam mana pula yang dimaksudkan dengan wayar yang tidak betul tu cuba terangkan, adakah dari segi size cable, quality atau ada benda lain.

spec amp?brapa ch?RMS watt tuk brapa ohm...sub 1 coil tau 2?klau sub wattage rndah pun, wiring tdk btul akan bagi stress dngn amp.tu la pnas.

klau double coil, myb itu amp ta stabil main 2ohm...so terpaksa la main 8 ohm.
tpi klau tu amp 2ch, tak perlu bridge dia.smbung sja d setiap channel la.ertinya d sini woofer ada 4 wire la suma.macam ni, amp stabil sbab 4 ohm sja.kebiasaan jumlah rintangan yg stabil untuk setiap amp kreta

ada kmungkinan gain d adjust terlalu tinggi.lebih half suda.boleh pnas juga.bnyak distortion

klau voltage dari batt dn altrnator yg kurang kena usaha yg itu la

taupn klau amp ta dpt angkat susa juga la...hehe

boleh ba...kipas computer 12volt juga 2.mau pndai atur brapa ampere la.sebab ampere*volt=watt...amik dari remote lebih slamat.sa rsa 2 ameron punya woofer tarik bnyak karan la 2.slalunya amp 2ch klau yg branded punya buli support 4/2ohm sja klau bridge.ada juga yg high end buli support kurang 1ohm.klau amp sa ni, bridge 2ohm pn tdk buli pegang suda.hehe 8 ohm pun panas juga.kesimpulanya, beli la amp yg berquality.

masalah amplifier panas melampau ni rasanya aku dah settle dah, apa yang aku dapat kesan ialah setup pada converter High-to-low aku pasal HU aku ni tiada low level output jadi kena guna converter.

masalah dia pada gain control High-to-low converter aku tu aku set kan paling tinggi, jadi sekarang ni aku dah rendahkan Gain control tu dan masalah amplifier panas melampau ni dah kurang, walau pun aku mem"blast" kepanasan amplifier tu tak la sampai boleh masak telur hehehehe......

ya pasal ada distortion la aku perasan itu gain control terlalu tinggi (dapat kesan masa setup 4chn amp) so aku kurangkan gain control kurang dari separuh.

teori aku pula mungkin terlalu besar signal audio yang masuk ke amplifier menyebabkan proses signal tu lebih menyebabkan amplifier perlukan current tinggi dari biasa. (macam tu ka tu aaaahh..... hahahaha)

itu distortion yg mnyebabkan amp panas tu. sbab voltege signal tlmpau besar pegi ke amp.jdi bila tmbah gain d amp lebih lgi besar tu signal smpai jadi clipping.cliping mksudnya signal di peak tu jadi rata suda.so amp kena bnyak power secara berterusan untuk play tu distortion.nasib baik amp panas sja.kadang speaker pun buli tbkar coil sbab clipping. hehe

gain pada amp mesti seimbang brdasarkan voltage signal dari HU.klau voltage signal besar dari HU maka amp punya gain pun kena rendah.klau signal dari HU rendah maka amp gain pun kena tinggi.tinggi mksudnya tdk smpai clipping la Smile

hehehe aku nda pernah pasang di kedai geng, semua pasang sendiri.
tapi nda pa la... belajar dari pengalaman konok.

rasanya aku terpaksa jugak tukar HU yang ada low output pasal sekarang ni masi ada distortion lagi walau pun aku set gain control kepada suku sahaja, atau mungkin high-to-low converter tu jenis murah tu la masih ada distortion (sangat sedikit), bagi org2 yang biasa dengar high-end punya sound pasti dah kena tolak ke longkang system aku, wakakakka....!!!!

direct means ko pakai converter ker.. Pada pendapat aku pula.. kalau macam tu lah masalah dia.. mmg power amp tu jenis cepat panas.. Class A punya power amp.. Brand2 lama jak pakai litar jenis ni.. Itu pasal arr dorg bikin class AB.. Pasal Class A ni mmg cepat panas dan bnyk kelemahan..
