Thread: using a 1 ohm amp to power 2 ohm subs?!

You could run 50 subs off that amplifier if you like by mixing parallel and series connection intermixed.

if you wanted to run 6 speakers off of that amp, where each is 2 ohms, then do the following:

Pair up subs so you have 2 groups of 3 speakers. Wire each group in parallel, plus to plus, minus to minus. Now you have 2 "speakers", each with a .6667 impedence. Now wire those in series and you have a 1.2 ohm load. Divide total power by six and each speaker is "seeing" about that much power.

If you need more power then run 3 amps.

My question for you is if this is a carpc forum, why does your first post have nothing to do with carpcs at all? There are hundreds of car audio forums out there that cater to this type of intellect.

mwahahaha, no edit on my post!

its a bad idea to put speakers in paralell. this will cause decreased bandwidth and give you waveform distortion on either end of the spectrum they were designed. But if you do, it will work and will not damage the amp as long as you have the impedence matched correctly. The reason why you get distortion when "piggy backing speakers" is due to the stray capacitances in the voice coils. Adding so speakers the one output with change the Q of the circuit that the amp is supposed to work with. This in turn gives you poorer audio quality than you would have had with a correct speaker. To correct this problem you can get a proper cross over which will allow you the 2 ohm speaker or two 2 ohm speakers, this will match the amp to the load.

Series or paralel?

and if you look at the capacitance, the alterations to frequency response fall outside of the woofers designated bandwidth anyways.

i need some help from anybody that know alot about car audio..i have a hifonics hercules amp and 3 hifonics 2 ohm subs. i want to wire them somewhere around a 1 ohm load because my amp puts out 2000 watts rms at 1 ohm. if someone can tell me how to achieve that ,that would be great. thanks...
