So would there be any noticeable difference going from a Cadence F-700 (800wrms @ 2 ohms, 400 watts per sub) to something like a JBL bp1200.1 (
JBL BP1200.1 (bp12001) Monoblock Car Amplifier, Power Amp) ~1300wrms @ 2 ohms? I'd be able to sell my old amp so it would only cost me like $50 to upgrade, but I still don't know what difference there would be if any.
The thing that confuses me is I know you need a double in power to have a 3 dB increase, but I've also heard that if you increase power, it might not make it louder, but make it 'hit harder'. What does that even mean, though?
