I am about to pick up 3 MTX Thunder6000s that are 4 ohms. I am also looking at picking up the Audiobahn A8002T. I am told by the shopt hat has the MTXs that right now they are wired on a 4 ohm load and that I could use a 2 channel amp bridged to 4 ohms or if I had a mono amp with 4 ohms.

Now anohter shop told me I can not use a 2 channel amp that is bridged at 4 ohms for a sub. Is that true? Can I use a 2 channel amp bridged for the subs? The subs are singal coils and not dual.

Thanks!

brian.. I don' really know how they connected 3 4ohm driver to get 4ohm output.. it's sound impossible.. With 3 drivers 4ohm/each, you will get the following output.
Serie ---> 12ohm
parallel ---> 1.33ohm
parallel and serie ---- > 2.67ohm

now you should know which amp you're looking for

The audio shops in your area are retarded. Both of them are wrong with some very simple concepts

3 4ohm SVC subwoofers making a 4ohm load? It's impossible. The only load you can achieve is 1.34ohms.

Of course you could bridge a 2 channel amp to run subwoofers. Why else would they make them bridgeable for a mono signal?

The amp you have chosen will not work with 3 subwoofers. It won't take the load. Try to find a mono amp that is 1ohm stable and puts out around 1000wrms.

Thanks for the info. Somone else at the shop with the subs did say it was hooked up at 2.67 ohms. Could I also just look for a 2 ohm amp?

yes brian, you can hook it up with 2.67ohm and have a MONO 2ohm stable amp, it will work fine and less expensive than 1 ohm stable (very expensive).

No you can't. The only configuration you can hookup safely is 1.34ohms.

I swear i just posted twice already what I am about to ask agian but I do not see it posted.

I found out the subs are 1 coil 12 ohm. What they told me today that it will be a 4 ohm hook up to the amp. Is that true?
