Selling my much beloved Rockford Fosgate P4004 4 channel amp. I’m the original owner, bought it from Best Buy circa 2006/7 I only used it for a couple years to push my mids/highs in my $400 1996 Saturn SL until the clutch bit the dust. 😂 It sat for 10+ years, then I started using it in past few years again to test out subwoofer setups. But now I’m ready to let it go. Works great, never pushed hard. Comes with the chrome covers, but missing two of the little Allen screws. I don’t have the original Birth sheet anymore, but as I recall it had almost double the advertised power, these were notoriously undersold, way more powerful than 50w RMSx 4, closer to 100rms. Ready to find it a new home.
