Your front setting (ignore sub) is too loud for the rear, so relatively the rears are sounding feeble.
Tune it once again, this time making sure that at any HU volume setting, Rear (fed from HU) is just less than Front (fed from amp) in the front seat. The amp gain knob is usually 270degress, so next time observe/quote the approx position of the indicator w.r.t. the left extreme. |
Thanks !
That's what I tried. This is what I did.
1. Sub switched off from HU
2. Front speaker gain set to 6V. (that's minimum? 75.4 runs from 75mv to 6V IIRC)
3. Fade to rear fully
4. Increase volume till rear sounds decent (not loud). This happened at around 40 on the volume 'counter'. Should it not happen at a lower volume?
5. Fade to centre/0
6. Increase front speaker gain till it juuuuust overshadows rear, i.e I feel a front footwell 'staging?'
7. Bring in the sub and set it's gain
But this way I found that I'm having to crank up the volume to 40ish (60%) just to bring the rears into play. Isn't this odd?
I mentioned 2-3V based on that 270deg twist. The fronts are set at slightly beyond the half way twist mark, more towards the 75mV end.
