I have Infinity Perfect 10dvq sub with dual 4 ohm VC's and Polk C300.2 2-channel amp.  Amp is rated at 4ohm stable bridged.

the sub is rated at 300w RMS and amp is 150w X 2 @ 4ohm or 450w x 1 @4 ohm bridged

Wondering how much DB loss i'm going to have buy wiring them in Series at 8ohm compaired to having each VC's on each channel.

Thanks in advance

One VC per channel VS VC's in series to a bridged amplifier results in the same net amplifier loading.  No change.
