So I just put my second amp in. Each amp is bridged at 4 ohms to one 8 ohm subwoofer. my subs used to be hooked together. They are the Dual 12" subs that you buy at Best Buy that are already in the box when you buy them. I opened up the box and split the wires. Now I have one sub on each amp. Now my subs barely hit, well not like they used to and now I have DOUBLE THE POWER! I'm kinda dissapointed. Is the 8 ohm sub putting to much stress on the 4ohm amp? Or is it the opposite? Any help would be appreciated. Thanks :mellow:
When you split the subs, the ohm load increased causing less power to go to the subs. The lower the ohms, the more power achieved.
Will this put stress on the amp? I just got them in today so I don't feel like blowing them up. They seem to run cooler...
There is no way you can bridge an amp at 4 ohms with an 8 ohm subwoofer...it is bridged at 8 ohms. Really you should hear no difference between one amp and two amps. The power should be theoretically the same. Say you have both subs wired in parallel for a nominal load of 4 ohms bridged to the amp. Power output is say 200 watts total. No you put an amp on each subwoofer with the amp bridged seeing a 8 ohm load the power is now 100 watts to each sub. Really though the higher the load the more efficient the amp meaning more power. But it would not be noticeable. Did you gain match the amplifiers with a DMM to make sure they are putting out the same voltage??
So I need to go out and buy myself a pair of 4 ohm dvc (or svc) subs? I would then get 460 rms to each sub. right? So really right now, I'm getting about 230 watts to each sub... correct me if I'm wrong. Thanks
