hey I'm fairly new to car audio. I understand the basics mostly but still need some help getting this all right. any help upgrading my current system would be awesome. I chose the parts before I knew anything and had a shop install it so I really don't have a whole lot of hands on experience, just from what I've read online.

so this is my understanding of what's going on, but I may be wrong. please point out my flaws

Current setup

  • Right now I've got an amplifier that is rated at 1,200W RMS at 1-Ohm. That allows it to give out 800W RMS at 2-Ohm, and 400W RMS at 4-Ohm.
  • I have a Dual 4-Ohm 10 inch subwoofer that is rated at 275W RMS. Since my sub is a Dual 4-Ohm, when wired to the amp, the final impedance is 2-Ohm. (Info taken from this photo)
  • Since my amplifier is rated at 800W RMS at 2-Ohm, and my Dual 4-Ohm subwoofer is wired at 2-Ohm with 275W RMS, I am overpowering the subwoofer by 525W RMS.


My ideal choice is to upgrade my subwoofer, rather than my amp to save money. So here are my options.

Option 1

  • Remove my current subwoofer and subwoofer enclosure, replace it with a dual subwoofer enclosure.
  • Purchase two Dual 4-Ohm 200W RMS subwoofers.
  • When the two Dual 4-Ohm 200W RMS subwoofers are wired to my amplifier, they will be wired at a 4-Ohm impedance with a combined total of 400W RMS. (Info from this picture)
  • Since my amplifier is rated at 400W RMS for 4-Ohm, this is a perfect match and my subwoofers and amplifier will be at an equal RMS rating. (That's good, right?)


Option 2

  • Remove my current subwoofer, purchase a Dual 4-Ohm 750W RMS subwoofer and replace my current with that
  • Since the new subwoofer is a Dual 4-Ohm, when wired to the amp, it will give off 2-Ohm of impedance.
  • Since my amplifier is rated at 800W RMS for 2-Ohm setups, I would be overpowering my subwoofer by approximately 50W RMS. (This is much better than overpowering it as much as I currently am, correct?)


Again I am a complete beginner when it comes to this stuff and am not sure if what I wrote is all correct. I would greatly appreciate any help fixing mistakes I made in my reasoning and help pick which the best option would be for an upgrade.

Thanks guys
