"This is a 50% less resistance concerning the Negative wire."

Yes but twice the current so the voltage drop would be the same.

The above assumes a mono signal. With a stereo signal, things could be really weird with all kinds of phase problems, etc.

My amp,is a Sansui Au 317, it is common ground, I am able to power Polk SDA 1B's.
The amp has cheap spring loaded speaker terminals.
Instead of replacing these terminals, I installed "jumper wire extensions"
and then took a small crossover board, mounted good female banana jacks on the board.then mounted the crossover board to the back of the stereo cabinet, it works great.
I only have 3 jumper wires,Left, Right and Ground.
I have 4 banana jacks, I jumped Left negative jack to the Right negative jack, then ran 14/2 wire to each speaker.
I do not understand the mingling of the negative signal being worse with the "Hybrid" scenario I suggested since the negative output is already
common.

  How long are the wires from the amp to the crossover?

    The cross-over board is a perforated plastic board, with the
    banana sockets mounted to it.
    The jumper wires from the amp output terminals are <6"long, 14 awg.
    The speaker cables are around 14' also 14 awg.
    
    Since speaking to you about a hybrid cable hook up, I added another run of 14/2 wire, per channel, netting me a 11 AWG equivalent.
    Better imaging, more relaxed sounding.
    The wires from speaker terminals to cross over sections are < 30", also 14awg.
    Wires from x-over boards to speakers are < 15",18awg to tweeters,14 awg to mid woofers.
    The speaker x-overs have been upgraded with better components, the the Hi pass and midwoofer sections were mounted on the back of the speakers (external) on vibration isolators for vibe protection.The 2 sections are 6-8" apart to minimize the cross talk between coils.
    The speaker were remounted with "hurricane nuts", I found the mdf baffle speaker mounting hole threads had turned to dust. Much better...
    nice sound....

should have known...... - walkstoslow 07:41:32 02/12/24 (0)
Thanks Tre:
No such thing as something for nothing, I should have known.
I am thinking of adding another pair of 14/2 wires.
2 runs of 14 awg equates to a single run of 11 awg.
I have never used such a large awg, maybe i will hear a difference.
Tweak I must.....
