I'm certainly a newbie when it comes to car audio and after countless hours of research I decided to call Sonic Electronix and inquire with one of their employees. The gentleman was not only helpful, but also gave me a superb price for these speakers. I was skeptical at first, but upon receiving them and having it professional installed there was a clear difference from the stock Bose that came with my Infiniti G20. The first few days I listened at loud volume and the bass wasn't as impressive as I thought it be, certainly not better than the stock rear speakers. But on the 3rd day, WOW!!! I was amazed at how clear these speakers were even at full volume the sound were crystal clear. On a scale of 1-10, I'd say the Bass response is about a 7. It won't rattle your windows or car, but it's tight and well suite for listening inside your car. I'm an audio engineer and have always been keen on things like frequency and sound placement. Needless to say, these speakers have provided me with the comfort of winding my windows up and listening to a track and being engulfed in pure audio bliss. I highly recommend these speakers to anyone working with a budget. On a final note, you will definitely need an Amp and Subwoofer.
