Who's right?
 

hi guys, i have been given conflicting info about amps rms power by what i consider to be reputable sources. i looking to buy a kenwood mono amp 9103d, i have 2 mtx 10" speakers 225 rms, 450 max. amp rms wattage is 500 rms X 1 @ 4ohms (900 rms X 1 @ 2ohms). i was told that the 500 rms @ 4ohm spec means that 500 WATTS will be routed to each sub by one source and the other source told me that the 500 rms would be split between the two subs(250 a piece. WHO'S RIGHT?

the 500 would be split between the two subs

correct....not that you need my confirmation, haha

I would hope the source that told you each sub would be getting 500 watts , is not a stereo shop .

it was actually a crutchfield rep that told me the bad info. is this amp to much for my speakers? kenwood 9103d

Technically they are both right. @ 2 ohms you are getting 450 (close to 500) to each sub. And @ 4 ohms they are splitting 500.

But if you read the original post , both sources were referring to 4 ohm power . I can't figure out why he would want to run that amp at 4 ohm though . Seems like you would want to use your amp to its full potential (2 ohm). Unless his subs are 4 ohm DVC and he can't get to a 2 ohm load .

My guess is there was a misunderstanding somewhere along the lines... Doesnt really matter in the grand scheme of things though... :rolleyes:

:confused: ok well i do want as much power as possible and obviously im new to the amp scene how is it possible to make a 4 ohm speaker run like a two ohm.

You can't make a speaker run . How speakers are wired to an Amplifier determines what ohm load gets put on the Amplifier . If you have (2) 4 ohm single voice coil subs wired in Parallel to that Kenwood amp . The amp will see a 2 ohm load and give each sub 450 watts of power . Are your subs single or dual voice coil ?

I have 2 4ohm 10"Kenwwod subs single voice coil (Handles up to 1000W peak power (300W RMS) wired to a mono amp whe you say wired in parallel do you mean + to + and - to - for the speakers

My amp is a Alpine 1000w Mono
1000W RMS (continuous) power x 1 @ 2 ohms, 14.4V, 20Hz - 20kHz, <1% THD
600W RMS (continuous) power x 1 @ 4 ohms, 14.4V, 20Hz - 20kHz, <1% THD

What is the correct way to wire these speakers to this amp ?

right now they are + to + and wired to + on the amp same witrh the neg side.

well, unfortunately you bought the wrong subs for that amp or vice versa.
wired + to + (parallel) puts a 2 Ohm load on your amp, which means you are running each of your subs at 500 watts....overpowering them by 200 watts......not good:eek: if you are going to keep your setup, make sure that the gain is set really low to avoid blowing your subs

this should help http://www.rockfordfosgate.com/rftech/woofer_wizard.asp

Ok thanks well at least I got the extended warrenty so if they blow I can just swap them out.
That web sight is helpfull thanks.........

the speakers are svc and the rms is 225 max. I did some research and figured out that I would be best to keep running it at 4 ohm

You can't run 2 SVC 4ohm subs @ 4 ohm mono(either 8 ohm or 2 ohm) . You can buy a 2 channel amp and run them 4ohm stereo .
