pros & cons of bridging 2 ch amp vs 1 mono amp to drive sub

Re: pros & cons of bridging 2 ch amp vs 1 mono amp to drive sub
 

Are you looking at 1 mono amp that drives the subs at equal power to a bridged 2 ch amp at the same ohm load?

for example: 50x2@4 bridges to 200x1@4 up against a 200x1@4 mono amp ?

If that's the case, there won't be very much difference between the two except cost. Monoblock amps generally are more expensive, not to mention don't come that low in power usually.

Most monoblocks are designed to run low ohms, 2ohms or 1ohms to achieve their maximum power, which is usually 400w or more. So you need a speaker setup that can handle that low ohm load.

I recall some discussion about what is better for a sub, running them off low ohm load power (like 1 ohm) or at a normal 4 ohm and the discussioned argued about the differences. I never paid attentioned because I honestly don't care THAT much. I'm not trying to win IASCA SQ+ competition ya know?

I think you should pick the amp based on the # of subs you want to use, the type they are, and the final ohm load of the subs, not to mention the cost you want to spend for an amp.

agreed +...
 

most sub amps are class d amps, which tend to be more responsive to producing quality sound at those lower frequencies. personally i would probably go with a mono block sub amp, if i was going the seperate amp route, only because those amps tend to cater more for a subwoofer (bass knobs, crossover points/ types, etc). but some 5 channel amps provide a sub channel, which is nice.

agreed ++ :)
 

when you bridge amps together you effectively add the noise created by each. So you usually end up with twice as much noise as one amp would have made... but in a subwoofer I seriously doubt your'd ever know.

until your sub siezes up due to a blown voice coil :P
 

i did it a couple of years ago on a sub i had for about two years. a little too much power and a little too much unheard distortion and the bass just stopped. checked the power, wires etc, touched the sub and no movement at all. it sucked at first then i laughed my butt off that i actually burnt one up.

I have also heard that low ohm loads (lower than standard 4 ohm)
 

can damage your alternator and the other electrical components in your car, as they create more draw on the electrical system.
