Ultimate under seat Amp Upgrade

Finally made the leap into a full-blown DSP setup. Pulled the trigger on the Helix P SIX Ultimate, since I have limited space and it packs everything I need into a compact package.

Went for an under seat install since that's where my 4 channel amp was, there was already a great grounding point and I need all the storage space I can get in the trunk.

I wanted to completely secure this so it has no chance of moving. I ended up with HEX head machine screws with nylon washers - so the screws wouldn't scratch the amp.

I bought a cheap pack of plastic cutting boards from Walmart and used the 8x11 size.

Cut the handle out to not interfere with cabling going through the opening. Created a template, drilled holes and installed t-nuts from underneath the cutting board. I used a few tiny screws to secure the t-nuts to the board.

Once I got the board in place under the carpet, I marked and drilled a hole for where a stud sticks out from the floor panel. To hold the board to the floor, I put heavy duty Scotch fastening tape to he bottom of the board, then put a nut on the stud going through it.

I burned holes through the carpet With a soldering iron and installed these "Desk Grommets".

These act as standoffs so that there was no chance of scratching the bottom of the amplifier. They also serve to center the machine screws and guide them into the t-nuts below the carpet. They also look much nicer than gaping holes.

I installed a 200mm Noctua fan under the seat, which I powered through an ethernet cable from the cigarette lighter inside the center console.

Once I screwed this down I was very satisfied that it was not going anywhere. Currently I just have my 2 way sysem connected to it, until I figure out how I'm going to mount my midrange speakers, but all the cabling is in place.

I just switched my stereo from network mode to to standard mode.

Going to start tuning this thing tomorrow!
