車 AMP / 啦叭 W數配合

唔好意思, 燜請問大家, AMP / 啦叭 W數配合 我忘記左...

係AMP W數大於啦叭W數, 還是啦叭W數可以大於AMP W數 ? 應該係AMP W數大於啦叭W數嘛?

先唔好講推唔晒還是唔夠聲先...例如:

一對啦叭標明200W, SUBWOOFER (600 W MAX / 150 W NOM) 咁計, 200x2 = 400+600
即係一部Maximum Power Output 1200 W 都已經ok啦? 對吧
  1. Number of Channels 4/3/2
  2. Maximum Power Output 1,200 W
  3. Continuous Power Output (1Ω, ≤ 1% THD+N) 125 W x 4
  4. Continuous Power Output (2Ω, ≤ 1% THD+N) 150 W x 4
  5. Continuous Power Output (4Ω, ≤ 1% THD+N) 100 W x 4
  6. Continuous Power Output Bridged (4Ω) 300 W x 2
複製代碼
  1. Number of Channels 5
  2. Maximum Power Output 2000W
  3. Maximum Power Output at 1 Ω-Maximum Power Output at 2 Ω 200W x 4 (A/B), 1200W (SUB)
  4. Maximum Power Output at 4 Ω 150W x 4 (A/B), 700W (SUB)
  5. Maximum Power Output - Bridged at 4 Ω 400W x 2 (A/B)
  6. Nominal Power (RMS) Output at 1 Ω-Nominal Power (RMS) Output at 2 Ω 100W x4 (A/B), 600W (SUB)
  7. Nominal Power (RMS) Output at 4 Ω 75W x 4 (A/B), 350W (SUB)
  8. Nominal Power (RMS) Output - Bridged at 4 Ω 200W x 2 (A/B)

太耐冇接觸音響, 好似依兩隻咁, 我都唔識睇了

要睇幾多channel, 每隻channel出幾多W
假設你前後左右全部各自用一個channel, 隻喇叭每隻75W, 咁咪隻4ch最少要每個channel 75W rms, 共300W,
如果你仲要拖多隻subwoofer, 隻sub woofer 一隻600W 咪外加多一個amp, 單ch 600W
睇隻amp 最大output無咩用, 你隻woofer 行4 Ω 同2 Ω須要的max rms watts已經唔同啦

車機基本50w x4,加隻有源SUBWOOFER
車機唔夠力,淘~揀class d擴音機,一機攪掂

唔係睇maximum係睇continous

一個50rms watts嘅喇叭 要有一個不少於50rms watts嘅供電 per channel

AMP一定大watt數過喇叭

例如--
AMP: 100watt RMS x 4
喇叭: 45watt RMS x 4
試AMP時唔好開咁大,Crutchfield網有教的,話要煲機慢慢較大.

我現時部車:
AMP Sony GM-D1004 (45watt RMS) x 4
喇叭: 前40watt RMS x 2, 後35watt RMS x 2

哦....咁我了解番好多

我本身前門有一對標明200w  後門唔落amp落住車機原裝啦叭(唔知幾多w, 暫時不明)

我諗住加隻冇源 600w 實烏化, 用一隻4ch或5ch amp推晒三隻, 但係咪以下兩隻都應該得?
  1. Number of Channels 4/3/2
  2. Maximum Power Output 1,200 W

不過5ch就....他朝一天屎忽痕連後門都想駁埋amp(或換埋啦叭落amp)的話, 似乎係用隻5ch會好d...

謝謝比意見

其實喇叭盡出20watt你耳仔已爆耳膜, SONY電視機10-15watt已經好靚聲
一般大牌字靚嘅40watt喇叭已經夠用, 你寧願買大牌子50watt喇叭,好過雞牌100watt喇叭。喺有分別的。

10幾年前玩車音響啲人話要裝大watt數低音砲要分開AMP。除非你要大Bass到黑鬼MTV兩個大12吋500w+,一般100w-200w 低音砲車內已經震到耳聾。大Bass行街好危險,完全聽唔到救護車聲。我有幾次差啲撞。


我最近睇中隻SONY 6ch 加DSP,外國有時做Promote好平,香港一定貴到趴街,淘寶得買賣2000蚊人仔有找。我相信依部野夠玩20年

4 OHMS: 45 W × 4 (FRONT/REAR), 90 W × 2 (SUBWOOFER)


再講,BASS 太大其他喇叭細Watt會唔平衡,BASS會蓋晒啲高音。BASS應該喺BOM BOM BOM,隔音唔好、擺位唔啱、Subwoofer調得唔靚會 WOH BOOM WOH BOOM WOH BOOB,啲門PANEL又震,嘥錢又唔好聽又阻位。

首先你個隻係咩喇叭先?200w係 max定rms?
同埋我個人意見係先揀定好喇叭再揀amp
至於sub就睇你想震車定想低音準
如果唔需要boom bom boom嘅低音 可以考慮下underseat嗰種

underseat好麻煩,通常櫈底有出風口

TOP

我個時部舊車都係落兩隻40watt都夠砌
