SEFIRO (1200 watt) 2ch 2ohm stable - Brothers (600 watt) 2ch 2ohm stable..

sy kira maw guna salah satu untuk main woofer MOHAWK orange 12 inci untuk lama2 full blast, mana yg dpt angkat? dan

..mana yg dpt angkat midbass evo-65 Borshmann 6inci 6 atau 4 speaker ?

Mica-filled poly-propylene Titanium cone woofer
Amorphous Titanium Dome Bullet
Freq Resp: 60hz -2khz
Sensitivity: 91db/w*m (SPL)
Nominal Impendance: 4ohms
Peak Power output: 200watts

sy pernah guna main KENBO 12V 4channel 200 rms(made in china) untuk main woofer mohawk orange 12inci + midbass 2 speaker evo-65 selama 1 jam atau kurang full blast ^_^ tapi amplifier tidak tewas tapi panas..tolong2 la guru!

wa ini mesti taiko-taiko sound yg tolong jwb ni Very Happy

secara teori la kn bro, klo mo tdk panas, cari amp yg lebih kurang atau lebi rms
dngn rms woofer.itu ohm pn mesti ngam dngn amp pnya stable ohm.correct me if m wrong What a Face baru blajar bah..hehe

SEFIRO (1200 watt) 2ch 2ohm stable - Brothers (600 watt) 2ch 2ohm stable..


kalau tnguk amp ko nie bgs ko pkai 2 brothers lh..angkt sebiji mohawk orange jak kn 12''..x mslh 2..sefiro 2 ok jga cuma sy rasa 2 amp clon pnya 2..jgn terlalu terikat ngan rms ngan watts nie..kdg2 watts kt amp 2 pndai tpu 2..tnguk woofer ko apa..

kalau psl amp mid apa2 jak amp 4 chanel dpt angkt jak 2..cuma yg beza suara 2..

2 chanle lbh ssuai angkt woofer..sngsara mid 2 kalau pkai 2 chanel 2.boleh jga pkai 2 chanel kalau bnyk mid 2 mcm 8 bji ka gitu...tp bgs pkai 4 chanel jak..

kalau ko tnya full blast brapa lama boleh thn?itu brgantung pada karan ko 2..bkn woofer n amp..karan ko drop amp ko akan panas 2..

Klu nak angkat woofer mohawk orange 1 biji saya cadang guna amp sefiro tu je. pastu guna brother utk angkat mid. amp brother tu blh angkat smpai 8 biji mid. klu nak angkat 6 biji x mslah. ko guna sistem 2.68 ohm. amp ko blh stable 2 ohm. jd klu guna 2.68 ohm pun masih ok.

karan drop amp panas? klau banyak karan mcm pula?

sekarang tgh pakai 6 gauge.

tinggal beli fuse baru, splitter fuse, 6 atau 4 gauge.

kira maw buat 4 gauge dari battery -> fuse 60A -> splitter fuse -> 6 gauge pegi 2 amplifier.


ooo..begitu, tapi kazen sy bilang tu brother lagi kuat konon.. sy tidak pasti la, dia yg ckp sama sy.

karan kereta tak pndai banyak. maksimum pun 14v je. cuma ampere yang kurang. bila kita blast sound kekadang karan drop sbb ampere yang kurang. tapi ampere x akan pandai banyak sbb keta kita pun guna karan juga. paling-paling pun ampere tu cukup-cukup makan je.

Cable 6 gauge tu ok juga tapi kalau ada budget guna yang besar sikit 0 gauge.

0 gauge dari battery ->fuse 60A -> splitter fuse -> 4 gauge pegi amp.

Amp brother tu mmg kuat kuat. tapi kena tengok amp tu depan mata dulu baru blh tau. berapa fuse yang ada dekat amp tu? yang SEFIRO tu pula berapa fuse?

adui...0 gauge mahal ohh...huhuhu..

maw 4 gauge la..murah sikit kali.. 6 gauge pe amp..

itu brothers (high mosfet power amp) shark B737 ada 2 fuse warna biru (15)
dkt control button ada,
Mode = ST,TR -
LEVEL = 5V,0.2V -
BASS EQ = 0 db,12 db
LPF & HPF
X-OVER = Flat and Both
High Input = 6 Lubang pg speaker kali.

si sefiro tu ada 1 fuse ja (15) fuse tu meletup X_X sbb sy bridge woofer + midbass..nasib fuse ja rosak..

Klu mcm tu amp brother kuat dari sefiro tu. amp sefiro guna untuk angkat 6 biji mid saya rasa blh kalau dia stabil 2 ohm. tapi kena tengok barapa watt dia blh supply untuk 2 ohm tu.

tapi rasa2 tiada masalah juga yang penting ko buat sistem mid ko 2.68 ohm.

awal2 suda sy ckp pkai 2 amo brothers kin angkt woofer ko bro..hihi..karan max 12v..bukan 14v..hihi..kalau ko pkai 1 bji woofer jak jgn pkai 0 gauge sbb tkt nnt karan bnyk stay kt wayar jak..skrg2nya pkai 4 gauge ckup uda dari bateri p amp 2..

kalau dua biji mid je ko guna, terminal (+) dari mid pi (+) yang satu mid lagi pastu pi (+) kat amp. terminal (-) pun sama juga.

paling ringkas, dari terminal (+) amp trus pi terminal (+) kedua2 mid. Dan yang (-) amp pi terminal (-) kedua2 mid. maksudnya satu channel angkat dua speaker.Dua channel angkat 4 speaker. wiring sama juga. Tapi kadang-kadang amp cepat panas kalau macam ni.

mid jgn smpai main 2 ohm..tkt nnt kalau amp tlmpau kuat mid boleh hngus..

Betul tu....
lebih baik main 4 ohm je...

pa mcm ko wiring bro?suma wire 4 speaker tu ko gabung trus masuk p 1 channel ka?yg mcm bro jlary78 bilang 2?
klo 4 speaker yg tiap 1 biji 4ohm wiring g2, ertinya amp tanggung 1 ohm tu...klo amp ok, ndapa la.

ahaks! ya..ala silap sy bah ni..patutnya 1ch - 2 biji speaker sahaja
adidididid..ingat satu channel 4 biji speaker.. sy faham sikit sudah pasal Ohm Om ni tau.. Very Happy jadi maksudnya 2 biji speaker 1ch bersamaan 2ohm? klau 3 biji mcm pula?

sistem ohm nie berdasarkan larian wayar ko dr negatice ke positive atau positive ke positive atau sebaliknya..contohnya larian positive mid yg satu ke negative ke mid yang lain lg dan sebaliknya..itu contoh shja..x semestinya ko pkai 2 bji mid antam p 1 chanel jadi 2 ohm..boleh jga kasi jadi 4 ohm..

ini cara macam mana nak kira ohm...

bila kita guna amp 2 channel untuk angkat lebih dari 2 speaker, kita boleh buat sistem wirring samaada secara parallel ataupun series...

contohnya kalau satu channel angkat 2 biji mid, dan kita guna sistem series:

terminal (+) amp -> (+) speaker1, (-) speaker1 -> (+) speaker2, (-)speaker2 -> terminal (-) amp.

kiraan ohmnya adalah:
OHM = speaker1 + speaker2
= 4 ohm + 4 ohm. (setiap speaker mempunyai impedance 4 ohm)
= 8 ohm.

Bila kita wirring guna cara parallel pula:

Terminal (+) amp ->(+)speaker1 -> (+) speaker2, dan
Terminal (-) amp -> (-)speaker1 ->(-) speaker2.
kiraan ohmnya adalah:
OHM = (4 x 4)/(4 + 4)
= 16 / 8
= 2 ohm.

kalau tiga speaker kita wiring secara parallel maka kita kena buat kiraan ohm untuk dua biji speaker yang pertama pastu buat kiraan untuk speaker yang satu lagi.

CTH: dua speaker yang pertama kita dah tahu ianya adalah 2 ohm. jadi speaker yang ketiga adalah:

OHM = (2 x 4) / (2 + 4) (dua speaker yang pertama kita gabungkan, speaker yang
= 8 / 6 satu lagi mempunyai impedance 4 ohm)
= 1.33 ohm

itu sy tau tu..tapi kadang2 bingung juga sama ni wiring dia ni..klau 4ohm speaker main negative ke positive - gabung 2 speaker dia jadi 8ohm?
pastu klau positive ke positive - gabung 2 speaker dia jadi 2 or 4 ohm?
