I recently purchased 2 Alpine 10 in E series subwoofers that are wired independently and a enclosed box the are 220watts @ 4 ohms each. I aslo purchasec a 450watt Alpine mono channel amp that has 600W peak output @ 4 ohms, bridged, 400W RMS (continuous) x 1 @ 2 ohms, 220W RMS (continuous) x 1 @ 4 ohms . I have heard to run the subwoofers in paralell, which to my understanding is run the positive of one sub to the positive of the othe and the same for the negatives, then run from that sub to the speaker out on the amp. Is this correct or is there a better method? Thanks for your help!
Yes you can run them in parallel. Just to avoid confusion, you want the positive of both speakers to hook up to the positive of the amplifier and the same for the negative. You don’t have to run from one speaker to the other but that will work as well.
I prefer to use equal lengths of wires for each speaker rather than jumping from one speaker to the next. Make sure to use at least 12 guage wire for best performance. Do Not under any circumstance wire in any type of resistor as was suggested.
As you will be running your amp down to 2 ohms, you will want to make sure your charging system is working properly, the amp is properly grounded, and mounted as such to allow proper cooling. All of these factors will determine the performance of your system. If you have any troubles, ask another question.
Cheers.
