Ok, i've learnt this somewhere in ICE forum but forgotten already. Didn't touch ICe for almost 2 years. I'm looking for Amplifier and Woofer now. So, i just wanna make sure both can match.
Now what i wanted to know is the ohm(s)...
Let say i got a monoblok amp that can do :-
- 300W RMS 4ohms
- 500w RMS 2ohms
- 700w RMS 1ohm
And woofer that states the specification as following :-
- 300w RMS 4 ohms
Note that I installing 2 piece of Woofers..
What i wanted to ask is.. If i connect the amplifier to run at 1ohm.. Will the woofer blow? Cause if i run at 4 ohms if not enuff...

QUOTE(kong5091 @ Sep 27 2006, 05:11 PM) What will happen if i connect 8ohm(home speaker) to a 4ohm amp?  That want i don't know.. That's why i am asking here.. The amp running at 1ohm.. The woofer will follow ?  |

I think u guyz mistaken already.. I am not asking how to wire it to get 1ohm.. That one i know.. I am asking... The spec on woofer states 4OHM.. if i wired the amp and woofer to run at 1ohm.. The woofer can blow/burn or not since the spec is 4ohms..

QUOTE(valve_300b @ Sep 27 2006, 05:26 PM) 2 pieces of woofer i suppose if both are 4 ohm, it should be 2 ohm if u wire parallel. no ur woofer will not blow if u wire it at 1ohm, in which if u have Dual voice coil woofer (both), it should be 1 ohm if u wire parallel. however, you can wire serial and parallel and it should be 4 ohm. But the 4 ohm wiring will not have as much power as the 1 ohm. However, it is easier to drive a 4 ohm than a 1 ohm woofer Kong, no it's not a problem connecting a 8ohm woofer. In fact, it is easier for the amplifier easier to drive it. edit: typo Thanks for the advise.. Now i get it.. It will not burn.. I know powering at 4ohms is easier.. Problem is monoblok amp that has 600w rms @ 4 ohms is crazy already.. I cannot afford that.. I can only afford those 300w RMS @ 4 ohms.. 700w RMS @ 1 ohm..

Erm.. The woofer i planning to get is 12" 300w RMS DVC 4 ohms..
2 pcs will be 600w rms...
If i run the amp at 500w rms @ 2ohms.. Not enuff juice..
The woofer i think can stand till 600w RMS.. More than that is burn liao..

QUOTE(craziechild @ Sep 27 2006, 05:59 PM) using a 8ohm will be easier to drive from your amp but the power will be divided... say the amp is 300w rms at 4 ohm... connecting it to a 8 ohm will be 150w rms at 8ohm only... and yes the good thing is the amp will run cooler and thus more efficient... and people who run 8 ohm are normally looking to control their sub bass more... while for the amp to run 1 ohm on a 4 ohm sub... i think shouldn't be a problem if your sub can handle all the extra power... over powering your sub will kill it faster... and your amp will be running much hotter than running 4 ohm... thus also shorten its life span... by how much depends on how you use your things... cheers... Yeah.. The question is " MY woofer can handle the power and 1ohm or not ? " .. |

QUOTE(howiechoo @ Sep 27 2006, 06:13 PM) no matter how many ohm, ur woofer sure can take it...the prob here is the RMS.....just dun go beyond the stated rms then it will be okay Ok then my problem solved here..  |
