preamplifier after preamplifier?


Hi.

I have a preamplifier and a poweramplifier I am very satisfied with.
The preamplifier is connected to the poweramplifier and the powerampfiler is connected to speakers,
The connection between the pre- and power-amplifiler is also spited to two active subwoofers.

However, I miss the option to control my sub-woofers volume relative to the speaker volume.
My pre don't have any settings for tuning this, just volume +/-

Can I connect a Second pre-amp with independent volume before the sub-woofers? will this cause any damage or problems?
It might be easier to understand this drawing:


Pre #1: pro-ject pre box s2 digital
Pre #2: AIYIMA Tube Pre

Using my Marchand crossover and passive subs, I set the gain on the crossover @ 10am and the mains at 3pm.  Quite a difference.  And I have very efficient speakers. May not help here but it is possible to use high efficiency speakers. 

I forgot to mention, or ask a question.  The first preamp has gain.  Feeding that to the second preamp, is that too much gain in the end?
