ayos lang ba kng 4 ohms ang ilalagay sa amp kapag naka bridge?

nakalagay sa likod ng amp o nasa manual ang minimum speaker load impedance in bridged mode. paki basa ng technical specifications. anong brand at model nung amp?

Bridged means switching from stereo power amplifier to function as monoblock amplifier. Bridging changes the amplifier's internal connection so that one channel amplifies the positive half of the waveform and the other channel amplifies the negative half. The speaker is connected as the "bridge" between the two amplifier channels instead of between one channel's and ground.  Better read your manual spec's for impedance load consideration in bridged configuration. Be safe (to your amp&speaker) than sorry.

ano po kc,
balak po namin bumili ng isang pares ng subwoofer tsaka amp...
ung subwoofer po 600w rms(8ohms) per pc..

tapos imbis na bumili kami ng 6oow/ch@8ohms  na amp
balak ko po na 1200w(bridged)@4ohms nalang ung bilin...
pwede po ba un?
ang alam ko po kasi madalas 16ohms ang required ng bridged eh...

salamat po sa mga replies

tama ka.

ang dalawang 8-ohm sub na naka parallel ay may total load impedance na 4 ohms.
ang total power handling naman ay 2 x 600W = 1200W.

pwede ang amp na may power rating na at least 1200W sa 4 ohms.

karamihan ng mga professional power amp ngayon ay kaya mag drive ng mabababang speaker load impedance na hanggang 4 ohms sa bridged mode.
