Bridged amplifier lost L/R balance

[harman.khinda]

Hi,

I have a PPI 900.5 and bridged the 4 chan amplifier side to power my two front speakers. I've lost my balance control. What did I do wrong?
I got the wiring info and link to the manual from this forum: PPI 900.5 - correct wiring? - Car Audio | DiyMobileAudio.com | Car Stereo Forum


Also this amplifier manual says it does 230×2 and 440×1 @4ohm. I dont get that spec b/c it can only do 270×1 if in 4 ohm mode. Also can you mix and match 4ohm speakers bridged with a 2ohm sub on this amp or do I need a 4ohm sub? I've read the manual to no avail.

RMS Power 4Ω 70×4 & 270×1
RMS Power 2Ω 115×4 & 440×1
RMS Power 4Ω Bridged 230×2 & 440×1
