I was worried about the RMS power handling of this speaker but it was all I could afford and I needed a 4". I am frankly amazed at the performance and have since gone 100% KICKER! 2 12" comp subs, 2 6X9's factory rear deck, these 2 4" in the factory door and two 5.25" the foot kick panels in a BMW 328is. The sound is unbelievable for the amount of money I spent. This little 4 is being driven at 2 ohms at around 75 watts rms. It throws the cone out like a woofer and handles it like a pro! I love Kicker they give so much product for the money!
