alan wilson Posted May 31, 2011 Report Share Posted May 31, 2011 hi all, I have done a bit of research about 8 ohm speaker and tweeters and i understand that the point of them is to reduce distortion for a clearer sound and that 8 ohms speakers/tweeters increases resistance therefore reduces power output from a 4 ohm amplifier, but i dont know how much power i will be loosing. i know i have 2 options either try and match the 8 ohm speakers with a 4 ohm amplifier (connect a 200 watt rms 8 ohm speaker to a 200 watt rms 4 ohm amplifier) and deal with the power and db loss, or i could connect i slightly higher powered amplifier to the speakers and hope the power is the same once it has been converted to 8 ohm power (connect a 200 watt rms 8 ohm speaker to a 250-300 watt rms amplifier) i have decided to go with the second option but i dont know how much more power i will need in ordor to get optimum power to the speaker. any help would be much appreciated.

Autruche Posted May 31, 2011 Report Share Posted May 31, 2011 Are they just regular speakers the you are going to use on a four channel? How many speakers, and what kind of setup are we talking?

Skullz Posted May 31, 2011 Report Share Posted May 31, 2011 8ohm speakers allow you to connect more of them together before going to low of an impedance for the amp to run them, depending on the amp chosen it may or may not sound better playing at an 8ohm load then at it's nominal impedance.

alan wilson Posted May 31, 2011 Author Report Share Posted May 31, 2011 i am basically looking at replacing all my exsisting 4 speakers in my doors and the other 2 in my parcel shelf with 8 ohm speakers because i am after clear sound rather than just loud sound, i dont want to connect 2 of them in parallel to make 4 ohm because to me it seems to defeat the perpose, i thought that by going with a higher impendance load would increase clarity with the sacrifice of power. these are the speakers i am looking at going with: http://www.audiosavings.com/products/Car-Speakers/BEYMA-6MI100-6.5-8-OHM-500W-MIDRANGE-MID-BASS-SPEAKER/6MI100.aspx Quote Link to comment Share on other sites More sharing options...
Autruche Posted May 31, 2011 Report Share Posted May 31, 2011 (edited) oh, I see. Due to the high sensitivity of the driver, I think you'd still get excellent output from it, even though it is a higher impedance than normal car speakers. I doubt there would be much clarity to gain out of running an amp at 8 ohms per channel, vs 4 ohms though. I could be wrong though. Edited May 31, 2011 by Autruche Quote Need Test Tones/Sine Waves?

skittlesRgood Posted May 31, 2011 Report Share Posted May 31, 2011 generally, if you double resistance you get half the power. so aim for an amp that does 2x the power at 4ohm.

skittlesRgood Posted June 1, 2011 Report Share Posted June 1, 2011 whats overkill? i have 500w to my 100w 6.5"s. i prefer to call it headroom.

skittlesRgood Posted June 3, 2011 Report Share Posted June 3, 2011 think i would notice if my speakers were not working?
