Reduced bass on acceleration?

[QUOTE="RobGMN, post: 8838367, member: 683408"] Running dual subs (final impedance 2 ohms) from a mono Rockford class D 500 watt amp. 4/0 wire direct to battery and ground. New stock (700 CCA or so). I haven’t been able to verify with measurements, but I can swear that the bass gets momentarily weaker when I accelerate away from a light. My first thought is voltage sag due to power drawn by ignition system during acceleration, but that is followed by thinking voltage/output should increase due to spinning up the alternator above engine idle. They should balance out. Aside from Doppler effect due to my incredible 0-40 ETs, any ideas? Anyone experienced anything similar? Given a D amp relies mostly on voltage and current with little capacitance behind it, could a reasonably sized capacitor help if it’s indeed a voltage/current sag issue? [/QUOTE]
