Has anyone had any experience with this HU? I recently decided to upgrade my stereo in my 07 civic si. The pioneer website states the HU puts out 22watts rms while many other websites list it as 14w rms. What's the deal? The HU will be powering a set of PG RSD 6.5 cs. Will the HU be sufficient to power these? Will my SQ be improved with this combo?
