Bridge multiple amp's

[flyingdingy]

Hi. I'm pretty new to this forum, and tried searching a little, but couldnt find what I was looking for...

I've got a bunch of older amplifiers of different power ratings (a 2x50W, 1x900w,4x75w, and so on).

what I want to try as an experiment is to bridge them all.... has anyone tryed that? is it possible? what would a theoretical solution look like? //content.invisioncic.com/y282845/emoticons/rolleyes.gif.c1fef805e9d1464d377451cd5bc18bfb.gif

if it worked it would save me some money (or give me more watt's at least) //content.invisioncic.com/y282845/emoticons/greedy.gif.5a53e6246569d7ab79867170f3b06629.gif heh..

thnx for all help

No, not possible to run all of those amplifiers on the same speaker setup.

We can pretty much tell you what will happen, and it won't involve getting usable power to a speaker...

For starters I think you're misunderstanding the actual meaning of the term "bridging," as evidenced by your inclusion of the monoblock amp (1x900) in your list of intended amps to bridge.

Bridging involves combining two amplifier channels to create a single, more powerful channel of output. (such as combining the two channels of your 50w X 2 amp to create a single output that would likely be in the neighborhood of 150 to 200 watts when in mono bridged mode)

The term you're looking for regarding your attempted use is "strapping."

While there are amps available that are strappable (sp?) to increase output significantly you cannot do this with any 'ole combination of units. Strapped amps have this tendency to necessitate they be the exact same amp as the amp it is going to be strapped to in addition to being designed to strap to another amp in the first place.

We can pretty much guarantee you that your eclectic mix of unused amps aren't going to fit the above description. If you attempt to connect the same driver(s) to the different outputs on your multiple amps unhappy things are going to be the result.

okei.. heh, well thanks =)

the thing is that I got two rockford fosgate amps (BD500's) "bridged" together (but also use a sync cable), so while connecting it all togheter (since all you basicly do is to run a wire from the + to a minus on the other one) I were playing with the thought on how it would all work out to try on some of the older amps.. but I too figured that it probably wouldnt work the that way...

but, something else, how much would a kicker R6 front set be worth second hand? would 60$ be a good price?
