the speakers you have sir are both 4 ohm impedance and the ARC 125.2 is stable at 2 ohms so yes you can wire them in parallel to bring the load the amp sees down to 2 ohms safely and without concern to the amp or speakers. Will sound awesome to boot!

Thanks for the help Guys! I heard Santa should have the Polk's here this week!
I'm running the amp from a Sony head unit using the RCA's. The Polk's are going in a set of lowers with the SE speaker pods, should sound good. (I hope)
It already surprises me sometimes with what it is now.

Series hookup is R1+R2, parallel hookup is a bit more complicated. When running speakers in parallel it's R1XR2 divided by R1+R2. In this case running 4 ohm speakers in parallel would be R1 (4) times R2 (4) =16 ohms, divided by R1 (4) plus R2 (4) = 8 ohms. 16 divided by 8 equals a final impedance of 2 ohms.
Perfect thank you!.. Thats what i was getting confused about..Did not know you had to multiply first .. Sounds good !! Looks like im good to go!

Marc, don't over think this bud.. the way this works; by connecting 2 - 4ohm speakers in parallel (2 for each channel of the amp, right and left) brings the load the amp will see to 2ohms. You are good to go in this configuration. But to answer your first question; yes wiring 4 - 4ohm speakers in parallel would in fact give you a 1ohm load. This is not the way you'll be wiring this up as you'll only be using 2 speakers per channel.

Scott Ezzell bracket
Hey everyone -- I heard back from Scott Ezzell regarding his amplifier bracket. FYI, he replied back right away to my inquiry, however I've been busy and haven't had time to post the info...
Scott said he designed the bracket to work with the Rockford Fosgate PBR 300x4 amp but he's also tried it with the Arc Audio amp. This is the biggest amp he's tried so far.
Here's a pic of the prototype bracket:
You can see the layout for the stock radio and CB.
Here's a pic of the finished product:
Looks good!
btw, sorry for the small thumbnails -- I couldn't figure out how to insert larger pics inline...
