Which opamp would you prefer using at a ±6 to ±7.2V (Split supply from car-battery buffered with BUF634T)? It will be used in an active crossover for my car.
I have some OPA2134 and OPA2604, but are there any opams that are better performers at this low supply voltage? Any help or input appreciated. PSU schematic:

I would rather prefer to avoid SOIC.

I've built a preamp run off two 9v batteries using the AD825s
It sounds great. The batterey (quite DC source) made a big difference. These can be run as low as 5 volts. I'm curious why Alcaid would want to avoid SOIC. I used BrownDog adapters to dip and about five minutes of eyestrain to mount three 825s. Many new designs are only available on SOIC.

My soldering skills are only average. And i was not sure that I could pull it off at first.
The Browndog adapters where very well tinned. I used an aligator clip to hold the chip in place on the adapter. used flux (as recomended by Browndog) and silver solder. It was actully very easy. A magnifying glass and a small tip on the soldering iron make it even easier. "Dare to struggle - Dare to win" That was either Walt Disney or Mao Tse Tung, I forget who.
