Ohm Mono
Posted on Monday, April 19, 2010 in Car Amplifiers
I have a 2 ohm mono amp & 2 each 4 ohm subs. If I wire parallel are my subs now 2 ohm, & does my RMS double?
I just purchased 2 Kenwood KFC-2511 4-ohm Subwoofers rated at 300 RMS and 1000 Peak. I also just purchased a Kenwood KAC-8104D mono class D amplifier rated at 500 x 1 (1000 peak) at 2 ohms. Now, I'm new at this so I'm not really sure what to do here. Do I wire my subs in parallel to get them to 2 ohms? Do my Subs now double their RMS ratings? ( 600 RMS/2000 Peak)
Yes - you will wire your subs in parallel for a 2 ohm load to your mono amp.
As far as the subs, as a pair yes - they together will have a 600W RMS rating together as a pair. However, your amp is rated at 500W RMS at 2 ohm which means your subs are getting 250W RMS each.
In regards to the "peak" power ratings - throw them out the window, they mean absolutely nothing.
