[QUOTE="Abquid, post: 8677332, member: 677233"] I don't know much about car stereo equipment, but here it is as I understand it. Originally, the stock Honda 8" sub and factory amp. First, this was replaced with a Micro Road Rage Amp 150w, and a Pioneer 2-ohm, 150W/600W 8" sub. The subwoofer sounded good, but there was a pronounced hum. Ground hum was found to be due to "underpowered" MicroRR amp (gain was turned all the way up). A Metra ground-loop noise filter was added to eliminate hum, but this also cut most of the subwoofer out. Finally, an Infinity Primus 6002A 280w amp replaced the Micro Road Rage Amp. I [I]think[/I] it sounds better, and there is no need for the noise filter anymore. [/QUOTE]
