zachhern1 Posted March 16, 2010 Report Share Posted March 16, 2010 Can you wire 8 door speakers to a 4 channel? My friend wants to put 4 sets of infinity kappas on 2 ohms in his front doors with the minimal # of amps. he already has a pair of jl w3s that will be going in there but plans on running them on a 2 channel...

zachhern1 Posted March 16, 2010 Author Report Share Posted March 16, 2010 ok thought that would work but wasnt sure....if the speakers were 90rms each how large of an amp would he need? 150 a channel? or 100 a channel? Quote Link to comment Share on other sites More sharing options...

ryde2idie Posted March 16, 2010 Report Share Posted March 16, 2010 do the math man. you have 2 90wrms speakers 2 ohms a piece on one channel. you can wire them to 1 ohm or 4 ohm. if you have an amp that can only do 150 watts at 4 ohms on a single channel then how many watts you think them speakers are gonna see?

dugee81 Posted March 16, 2010 Report Share Posted March 16, 2010 he could wire in series if the amp could handle 2 x 4ohm bridged. i have a two channel that is 400wrms @ 4ohm bridged and i have 4 speakers wired in series and then in parallel to make a 4ohm load.

I know i sound like a dumbass but Ive had ppl tell me that the speakers will get 150 watts..so each speaker would get somewhere around 75 watts each?

ryde2idie Posted March 16, 2010 Report Share Posted March 16, 2010 you dont sound like a dumbass itll just help you understand it better if you figure it out pen n paper stlye. but yea your right 75wrms as long as the amp is seeing the resistance its rated for. if you lower the resistance of the circuit the wattage will go up.

zachhern1 Posted March 17, 2010 Author Report Share Posted March 17, 2010 ok thanks man that helps me..ill tell my friend to find an amp with 150-180rms per channel. Quote Link to comment Share on other sites More sharing options...
dmanson Posted March 17, 2010 Report Share Posted March 17, 2010 Something such as a good four channel 600-800rms amp will get those infinity speakers to singing nicely.
