yes... kinda...

low level inputs are via RCA jacks and the level in voltage. usually less than 1 volt.

high level is using the speakers level, like the OEM head units in the WRXs.

preferred way is via low level since you are getting clean data where as speaker level, you are getting the data plus any noise from the amplifier too.

I am thinking about simply unbolting the seat and using on of those bolts to hold the amp down, but it seems it would be quite a pain in the *** to work with that way. A bracket of some type seems better...
I screwed down a small MTX amp using self-tapping screws to the floor under the passenger seat. There is plenty of room there.. not sure about the driver side though.

What I would do is mount the amp to a piece of plexiglass or vinyl (sheets can be found at Home Depot for like $5). Then I would use Industrial strength Velcro to secure it to the floor carpet.

I don't like drilling holes in my floor especially because of rust and water invasion. But hey, that's just me. I've personally never wanted to install amps under seats because I like to give amps more airspace to cool. I usually mount mine on my sub box or make an amprack and mount it to the back seats on the trunk side.

Your amp will get better ventilation in the trunk as well. It might not matter in your case since that is a small amp, but there is not a lot of clearance for heat to dissipate under the seats. I recommend mounting the amp on a sheet of mdf or particle board and then attaching it to the back of the rear seats w/ screws or bolts. You also have better access to it in the future if you want to make adjustments or add on to your system.

I've got a medium-sized amp under my seat in my wagon. Haven't gone through a summer yet, but no heat problems so far. It is pretty invisible, mainly because my seat is usually slid most of the way back. There are big holes cut in the carpet for the floor vents (can help with amp cooling if you place the amp right), so running wires under carpet is doable with some patience and some stiff wire (10 gauge solid copper works well) or someone probably makes a wire snaking tool you could buy. I've got it mounted to a piece of 1/8" sheet metal, that is velcroed to the carpet. Works like a champ.

Bolt that stuff down so it won't be so easy to steal.

mounting amp

Subaru sells an under the seat subwoofer that has a bracket to mount it under the seat. I imagine that with a couple of extra drilled holes to accomodate the amp, that this bracket would be perfect. The actual bracket is attached to one of the seat bolts. Also this won't affect the interior in any way.
