 Posted: Apr 06, 2005 8:35 pm Post subject: How to I get the most juice to my evids using the following |
 |
|
I have a 4 chan amp it's 800 watts total so 200 per chan.. From what I have read on the site so far I will put the evids in parallel and then bridge them. But it is a 4 chan amp can I bridge/combine all four channels ? oh evids are 8 ohm
Thanks

You can bridge channel 1 and 2 together into left Evid and 3 and 4 together into right Evid. Your amp will deliver whatever its 4 ohm rating is per channel. Im pretty certain your power rating of 200 watts will be into a 4 ohm load so thats 400 to each Evid.
You cannot double bridge
Remember the rule with bridging two amps -
"Double the power into double the impedance."
Good luck

I'll echo the previous "don't bridge four channels down to one" comment. That's a big no-no. As to the final input wattage you'd be feeding your Evids with the your current amp, consider this.
Your amp = 200watts per channel @ 4ohms @ What Voltage?
If you bridge channels 1 & 2 to your left Evid and channels 3 & 4 to your right Evid, the input wattage will only be 200 watts per speaker (i.e. 400 watts out of the amp @ 4ohms into an 8ohm speaker = 200 watts per speaker. Realistically, the input power will be even lower than that because most amps are rated by their manufacturers at unrealistic voltages (like 14.4V or higher). So in the end you may actaully only be pushing something like 150 watts or so into each speaker. From my experience with these speakers, that amount of wattage isn't going to tap the potential of the Evids.
Here's something else to consider. If SPL is your goal, I'd suggest a different amp scenario. Wire your two speakers together in parallel yielding one 4 ohm channel. Then install a large two channel amp bridged down to one 4 ohm channel. Just as an example, the Kicker KX550.2 amp will bridge down to 550w x 1 channel @ 4ohms (Mono). That input wattage should really wake up your Evids and get the most sound possible out of them. |

Well I guess my amp will run 4 and 8 ohm speakers so I guess I don't neet to worry about the 8 ohm predicament. I'll just bridge chan 1/2 and 3/4 and I should be off to the races

Let us know after you get everything wired up and tested, if you can actually hear anything while boarding. My bet is you won't hear much given the amount of input wattage you're gonna show those two speakers. |

Waketech,
I think you had the same post on wakeworld. There was good information there. If you bridge each evid to 2 channels, you'll be running an 8 ohm load and working your amp like crazy. I don't know if you may overheat it. If you run them in parallel to just 2 channels, you'll get the same output to the speakers, leave 2 channels open on your amp, and not work it so hard.
