A pair of GNX124's

Systems

I have a pair of GNX124's connected to a Bazooka dual channel 500W max amp. I want to bridge the amp using both speakers. The amp recommends a minimum of 4 ohms for bridged. Is there a problem doing this? Is there a way to wire the speakers to make this work?

thats a 4ohm speaker right?
pretty sure the 124s were the 4 ohm models
in which case no, you cannot bridge it, it will fry the amp

Thanks Cody..

I am wondering though... Am I loosing any sound quality using the amp normally versus bridged? I just bought these speakers and they sound awsome connected to left and right channels.

I used to have a single 10 inch bridged.

Just wondering if it makes enough difference to bring them back for 8 ohm speakers which I can bridge. I got these for great price, 112 for both.

If sound difference is minimal then I will keep them as is.

sound quality will be the same, if it puts out more power in bridged
for example 75x2 or 200x1bridged then youre getting 25 more watts to each speaker and itll be louder
i would not exceed the RMS power handling though, but if youre not and bridging increases your power, then id trade em out

well, sq stays the same for most subs (it'd take one hell of a driver to hear the minor distortion introduced by bridging).

That's not true. You can bridge teh amp but you will have to wire the subs in parallel (I think. Parallel adds impedance, Series divides added impedance by the number of resistors in the circuit) However, if you wire it in parallel, you will only be running an 8 ohm load and it will be half as powerful as if it had the 4 ohm stereo load. The only real benefit is that you can pretty much be sure that the amplifier will have lotsa head room beyond the rated 8 ohm power so there is less of a chance of the amp clipping at high volume levels.

true, but itd probably be louder to just have one sub running bridged off the amp...

jstas is right, esp. about the headroom bit (bridging drives an amp to its max all the time) but i think he got his series and parallel mixed up. connecting two 4-ohm subs in series yields an 8-ohm total load on the amp, paralleling them yields a 2-ohm load.

i think that this is your amp. in that case, running the two subs you have off separate channels yields 115W to each. this amp does 330x1@4, so if you series your two subs on the bridged amp, you're getting... 57 W apiece... eew... im pretty sure the subs are 175 WRMS. um... with 2 8-ohm subs, you get... 115 apiece again. and one sub cant take the 330 from the bridged amp...

end result: id stick with the subs you have now, one off each channel.
