2ohm vs 4ohm

[CaRLo_o3]

mga tol...ano difference ng 2ohm sa 4ohm? wat if ung subs ko isang 4ohm at isang 2ohm? mganda pa ba tunog nun? at anong amp ang dpat gamitin?

[Horsepower]

Dapat yung amp na kaya mag-drive ng 1Ω

[niwde11]

dalawa gagamitin mong subs with different ohm? on a 2 channel or 4 channel amp? kung 2 ohm load mo, be sure 2 ohm stable yung amp.

[CaRLo_o3]

*niwde11 - hiwalay ba dapat sila ng amp? o kayang ibalance ng isang amp un?

[CaRLo_o3]

*Horsepower - so dpat ung amp na gagmitin pwde pang 1ohm?

i am asking why two subs with different omhs? di pa ba sufficient yung isa.
kung gusto mo talaga gamitin yang dalawang sub kahit isang amp lang na 4channel bridgeable(ie. magiging two channel sya at bridge mode) pwede na.

[CaRLo_o3]

ok...isa nlng gagmitin ko na sub....nu po pla magandang setup kung spl? may kicker s12L7 nko na sub...nu pa po ung ibang kelangan idagdag?

2ohm subs can give more power compared to 4ohm subs... 2ohm subs should be driven by 2ohm stable power amplifiers... 2ohm capable amplifiers can drive 4ohm, 6ohm, 8 ohms and 16 ohms speakers while 4ohm capable amplifiers are limited to from 4 ohm to 16 ohm speaker variants..

assuming you use a 4 channel 2ohm stable amplifier via bridged mode and connecting two subs with different impedance, the amplifier can drive both subs and you may notice more power on the 2ohm subs.. but the power given by each side of the amplifier will not be balanced.. with this you will notice that the side where the 2ohm subs is connected will get much hotter compared to the side where the 4ohm subs is connected... still you need to have super sensitive bass senses to feel the power difference from a 2ohm sub to a 4ohm sub using the same amplifier..

2ohm subs works better with a dedicated 2channel amplifier for sub since they have fewer MOSFET IC using the heat sinks compared to 4 channel amplifier that has more MOSFET IC that shares with the same size of heat sinks used in a 2channel amplifier

to simplify, the lower the impedance, the more power you can get and juice out from your amplifier, but your amplifier is under more stress due to the low impedance and may overheat!! (your speaker is almost in "SHORT" state if low impedance, a burn out speaker will have an impedance of infinity "OPEN" state)

tnx yapoy...

carlo; try to browse at www.kotseaudioclub.com. halos lahat malalaman mo dun from newbies point to view up to the extreme ones.

Very well said!!! nice!!!

ano specs ng L7 mo?

[CaRLo_o3]

12' 4ohmDVC

[atomiczen]

ganda na yang sub mo a.. mga 750rms yan.
kung isang s12l7 dvc4 ang gagamitin mo, better get a 750wrms or higher *2ohms mono amp. kung 2 subs gagamitin mo, get another s12l7 dvc4 and get a 1500wrms or higher mono amp *1 ohm stable.

tapos ported box
kung kaya pa ng budget get a high voltage hu.. mga 4volts or higher.
boom boom na yan!
hth :D

[CaRLo_o3]

boss ano magandang mono amp na may 750 rms * 2ohm?
puwede ba sa 4ch amp yung sub given na naka bridge ito?

[yapoy86]

DVC subs only allow you to have flexible wiring capability since you can wire them at 2ohms, 4 ohms and 8ohms..

do not connect this where in a single DVC sub was connected to a 4channel amp at bridged, the setup was channel 1&2 was bridged then connected to the Sub at 4ohms then channel 3&4 was also bridged and connected to the same sub on the other side..

your amp will overheat and your sub will not play properly..

also you may use HU with 4V to 5V line out
