bridging 2 mtx 12"s..

Question. I have heard from some people that you cannot bridge 2 4 ohm subs and run them parallel that it would make the amp "see" 1 ohm. Is this true?both subs that I am using are SVC

what amp and are they single 4ohm coils?

Its called bridging when you add power supplies together. On speakers, just say parallel or series. If the subs are 2 ohm you would end up with 1 ohm. If the subs are 4 ohm you would end up with 2 ohms.

Correct. but the amp is 2 channels.. I didn't know if I were to bridge the amp and run both of the 4 ohm speakers in parallel if the amp would "see" 1 ohm. figured since its sharing two channels using 1 speaker bridged would cause the speaker to go to 2 ohms? So if i were using 2 it would be 1 ohm.. I might be misinformed the reason why am asking.

is that amp stable to bridge to a two ohm load,if not dont do it

yes the bridged amp will see half the load on each side,,,if im not mistaken

The final impedance allowed on the amp to run bridged would have to be 2 ohms, if you run two, 4 ohm speakers in parallel. The amp doesnt change the impedance of the sub.

It wont have sides when bridged, they act as 1.

final impedance of the subs wired or what the amp is seeing on each channle?

thats what I am trying to figure out right there

the amp will still have to side they are just being combined

 

[pr-festiva 10+ year member]

easy fix call an amp company and see what they say

 

[pr-festiva 10+ year member]

what amp is it????

Nope, two sides means 2 positives and 2 negatives, it does not have two sides when bridged. If it was wired up to have two sides you would be unbridging it. When bridged, amps channels are, to put it simple, series wired to get 1 large channel.

im talking internal not external if his amp says 100x2 at 4 ohm,,200x2 at 2ohm,,then it should be 400 at 4 ohm mono,,which would be the bridged channle seeing half the ohm load wired to it right
