PXA-H700 optimum set up...
The way the EQ is hooked up is correct.
You set the factory radio to a set level, then use the volume on the EQ for everyday adjustments.
I believe your problem lies in the amplification.
Your BOSE amplifier was made to run a 4 channel 8ohm stero load.
Low powered - high in sound quality.
You have swapped the factory 8 ohm speakers (15W) for 4 ohm power hungry ones.
Now the amplifier is working harder to produce the same output.
You would be best served eliminating the factory amplifier and getting 1 good 4 or 5 channel amp to power your speakers.
a 4 channel amplifier could be used stereo (left and right) on channels 1 and 2, (2ohm stereo load)
and bridge channels 3 and 4 for your subwoofer.
For a true surround sound - a 5 channel amplifier could run each speaker individually, and the 5th channel is reserved for the subwoofer.
a small dedicated 75wx4 channel amplifier with built in crossover, and level gain controls - would blow your socks off. It is 200x better than the factory 12Watt amplifier. Your ears will love you for it :D
If you need more help - just let me know.
