wtf? you serious?

what do you mean total rms? are both the speakers going to the same amp?

You arent gonna want more than 50rms so you dont blow the one speaker. but if your using different speakers you shouldnt connect them in parallel or series, its bad for the speakers and amp.

The case is I have 2 tweeters , 4 speakers , sub and 2 amp of total 9 channels. not installed yet

I thught about 3 different wirings

1-Tweeters and front speakers and sub to one 5 channels amp

and rear to bridged 4 channels amp.

I may lose fade in this case.

2-wiring tweeters and front together in serial because they are 2 ohm and all connected to the 5 channels amp , no need for the 4 channels amp

fade is OK but I don't think tweeters and front will be in the best shape.

3-wiring tweeters to the HU and the rest to the 5 ch amp.

tweeters will not be in the best shape.

what do you recommend.

BTW this case is just temp case I ordered Alpine comps for front BUT will arrive in 3 weeks. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

why not ditch the 5 channel and get a mono block for the sub. Then run your speakers off the 4 channel. It would be better for the sub and speakers.

What amps are you using

What amps are you using

JBL CS60.4 and Alpine PDX-5

well ill tell you what i did.

hooked my 4 6.5 alpines into my 4 channel amp(100rms each). each speaker to its own channel. I have my small 4x6 sonys connected directly to my headunit(~50-75rms each). then i have my 2 subs wired in parallel and series down to 2ohms going to my mono amp.

with the alpine you could do 4 of the speakers to 4 of the channels and the sub to one channel. this will give you 75rms per speaker and 300rms for the sub according to the specs i found online. then you could run your tweeters from the jbl amp.

as for your original question

total rms doesnt change no matter what way you wire. if a speaker is 50rms itll take 50 rms. its the amp that matters about the wiring. also its series not serial

I think I could not explain my question , yes 50 RMS will be 50 RMS ,

what I mean is with series wiring the resistance will be 4 ohm instead of 2 ohm

So I still have to power them with 50 RMS?

One question , wiring only 2 channels of 4 channels amp , will not cause a problem to the amp itself?

i would love to see the hu that can produce 50-75rms per channel.

it does around 30 per channel and i have the speakers bridged over 2 channels. Im just guessing at the actual wattage

just using 2 channels shouldnt be bad but i dont know for sure
