Whats my best option for my bridged 2 channel amplifier ? Please Help !!!?

Question

I was jus wondering what my best option was with this amp i was told to buy a dual voice coil 2 ohm subwoofer and to bridge my amp and connect the sub parrallel which would get me to 1 ohm. I would just like some ideas and some opinions with this amp to get the "best bang for buck" as they say lol.

ANY INPUT WOULD BE APPREIATED

Answer 1

Your amplifier is rated for a minimum of 2 ohms in bridged mode, not 1 ohm. If you want a single sub, you could get a dual 4-ohm subwoofer and wire it in parallel for a 2-ohm load. If you want two subs, you could get two of the dual 2-ohm voice coil subs you mentioned. Then you could wire the voice coils in series so each sub is a 4-ohm load, and wire the two subs to the amp in parallel for a 2-ohm load. Alternately, you could wire each sub for a 1-ohm load and connect them to the two amplifier channels in stereo.

Basically, if you bridge the amp you need to keep the impedance at 2 ohms or higher. If you run the amp in 2-channel mode, each channel can be connected to a 1-ohm load.

Answer 2

Notice there is no rating for 1ohm bridged. It's likely that your amp will overheat and/or fry if you try to run it 1 ohm bridged. I wouldn't recommend that. You can get a dual voice coil sub with each coil @ 4 ohms and wire it parallel to get a 2 ohm load which will produce the 640 watts @ 2 ohms bridged.

Very few amps will be stable at 1 ohm bridged - if it is it's going to be a very expensive amp.

Answer 3

If you don't want to spend more money on your system, your best option is just to connect each sub in its own channel, since your amp is only 2 ch, you can bridge just one sub, (assuming 2 ohm minimum impedance). Using parallel connection in bridged mode with 2 ohm speakers, will make the amp see a 1 ohm load at the outputs, but since your minimum impedance is 2ohm , your amp would definitely burn. If the money is available you should buy another amp identically to yours, or a more powerful amp.

Answer 4

1 ohm is going to bang hard. just remember the lower the ohms the easier it is to blow your sub. i suggest using the new orion hp 2 ohm. it knocks like a champ. i paid about 250 for it a few months back. ive seen them on the internet for about $130
