Does the RMS change when you put subs in parallel?

[kdude13]

I want to put 2 10" Kicker subs in my truck. They are 4 ohms SVC with 300W RMS. The amp I was going to use is rated for 300W at 2 ohms. If I were to run them in parallel, would the 300W RMS still be enough for both subs?

No.

You'll have 150w per sub, which will be fine. 300 ea would be better, but only at 2-3db increase. Low-mid volume listening would be about the same.

150 per sub BEFORE box rise.

Need more power.
