I have tried several different comparable systems in the $100-$150 range & the Sound Storm SMC90BB has, by far, the best sound quality and most power. Absolutely blasts on city streets & I have no issue hearing the sound loud and clear at 65 MPH. So far it has worked great in wet (rain) conditions as well. Easy to install and I especially like the wired volume control. The only improvements I would recommend would be longer speaker wires, a bracket for the wired volume control, and an independent on-off switch. These were not an issue for me as I was already set-up for this but I can see someone installing a stereo for the 1st time needing these.
