speaker hook up options

Its been awhile sence i delt with the best way to hook up woofers. if i remember correctly you can run speakers 3 differnt ways.....
1. hook them stright to the amp each speaker having its own positive and negitive connection to the amp thru the right and left channel. if your speakers are 4 ohm then each channel gets a 4 ohm load.

2.hook them up in series where the positive comes out of the positive of the bridged channel of the amp to the positive of the first speaker then negitive of the first speaker to the pos. of the second speaker, them the negitive of the 2nd speaker back to the amps negitive side of the bridged channel. so if you have 2 4 ohm speakers you are giving the bridged channel an 8ohm load.

3. hook them up parrelle where you hook both speaker positives to the postive of the bridged channel and both speakers negitives to the bridged negitive channel so if you have 2 4 ohm speakers you are giving the amp a 2ohm load cause both speakers are hooked to the same channel.


ok so if this is all correct what is the best way to hook up the speakers??? the amp is a 2 channel 600 watt amp. the speakers are both 650 watt 10 in. the amp is brigable using the right positive and the left negitive.

the next question is do you still hook up both rca jacks cause the amp shows the left rca jack as the btl channel. im a bit confussed about the stero and mono and how it effects the ohms and the load on the amp.

any help you can offer would be great.

Yes, both jacks..
for starteers, what kind of amp is it, as well as speakers?

a "bridged" amp, utilizes the Left Positive and the Right Negative outputs of the two channels, usually.. So you need both jacks for input..

im not so sure about waht you said...i think you have it messed up...with the ohms and stuff...but i dont really remember anymore...the safest way to run it is in series...like you said...that way i believe it will draw less power from the amp...if you do decide to run it parralelll then it will draw more power form the amp....and that might fry the amp...or cause the "protect" option to turn oin...

His scenerios are correct..

And you are correct, kinda... Many amps today are designed to handle the low-impedance loads, like .5, 1, 2 ohm impedences... Cheap s**t like Legacy, etc.. doesn't like the low impedance/high power output setups.. They tend to :"let the smoke out"...

But mainstream amps will usually handle at least 2ohm mono load, or at least a 4 ohm mono output..

:haha:
All those cheapo swap meet flea market brands tend to do that under a 2 OHM load. :lol:
All my buddies learned that the hard way back in high school. ;)

dont forget that bridging an amp automatically cuts the impedance in half...so what ever ohm load you are wiring divide it in half...

Do what?

If the amp is capable of a bridged 2-ohm mono load, then you wire your subs to produce a 2 ohm load - where's it get cut in half?
Match your wiring configuration to what the amp can handle efficiently.. If the amp will handle 2ohm mono bridged, then 2-4ohm subs paralleled is correct.. or a single 4 ohm, dual voice coil sub with the vc's wires parallel, or whatever. The amp "treats" it as half of the wired resistance, therefore producing more power.. That's the theory behind the whole mono-bridging thing... Therefore, a two-ohm mono configuration, wired to a 2ohm stable mono (bridged) amp, effectively sees 1ohm per channel, therefor increasing the overall output power

Or am I missing your point, kaace? :what:

if you wire a four ohm woofer to a bridged amp the amp sees it as a two ohm load...
