Mach 1000 Removal

I just recently took out my Mach 1000 audio system. For those of you that have done this, what did you do with the bolts that are sticking out from the floor? Did you just leave them? I might want to install another sub setup but these bolts look like they aren't able to be pulled out from the floor. I don't want to cut them because I might put the Mach 1000 amps and speakers back in one day. What did you guys do?

Thanks

It's a great system. My ears are just a little more picky than the average joe since I'm a record producer and my car is a place where I check out my new recordings for any flaws. I am in the process of custom tuning a new system to go in the car that will be more powerful and crisp.

The Mach 1000 is loud enough to get the cops called on you though! It is the most powerful factory system you can get and very well put together (although they could have designed the setup better as far as space usage goes).
