Hi

I will build myself filter for car amp, so I would like to know if this one is ok, what could be better, diffrent or anything else. I will use two TL072, so I got 4 op-amps, 3 are now in good use last one is just to have it in use, I don't need phase to be changed at least not that I know

Would you like a couple OPA4134 in 14SOIC to play with? Think of it as a gift for trying to help me with my SMPS.

Also, I know you are perfectly capable of making your own +-15v switching supply to power this project, but I have some very compact supplies I purchased specifically for car audio projects. I had to purchase more than I needed just to get a good deal, so I have extras. Your more than welcome to one.
