Using Tape Out from Preamp for powered sub woofer.

Hi, It may sound stupid, but can a Tape-Out from Preamp be used for powered Sub Woofer. I'm looking at constant bass from sub. So more bass at lower volume and relatively less bass at higher volume. Are there any technical disadvantages if the Tape-out is used for power subwoofer?

That should plant the woofer cone firmly in your cranium.  Tape out equals full volume to the sub with no control from the preamp!

Couldn't the OP use tape out and control the volume from the sub as he/she wants different levels depending on volume?

Noromance, your question is correct. 
To clarify my point further, I do have volume control on my powered Sub.  And I need more bass when I'm playing music at lower volume, which is the case most of the time. And as I increase volume from preamp the bass from the sub is too much for my taste. And I hate to standup every time to reduce bass level on the sub. So I want to bypass the preamp volume control for subwoofer. I would like to try this arrangement, but just want to make sure it's technically correct and will not damage preamp or the Sub.

As long as you don't mind adjusting the volume on the sub, I see no issue. Try it and see starting off at the lowestvsetting on both pre and sub.

You may also be able to use a quality Y-connector at the end of your IC cable from your preamp output (not tape out) to your amp. So, run a second IC from the Y-connector to your sub(s). This will allow your preamp to control the volume, but you should still be able to adjust the gain control on your sub(s) when playing at low volume.
