2012 Civic Si Build Log

[seg_representin 10+ year member]

Finally finished my build last weekend. Car is a 2012 Civic Si Sedan. I still have to fully deaden the doors, clean up the mess of wires in the trunk, and carpet the sub box. I'm doing a 2-way active front setup with no rear fill. The box will probably be just a temp box, just wanted to get some low end in quickly. On to the build....sorry if the pics aren't that great they were done off my phone.

Equipment:

Fronts: Sundown SA-6.5CS

Processor: Rockford Fosgate 3sixty.3

Subs: 2x PG RSD10's

Amp: Alpine PDX-V9

-Factory sheet read 129x4 and 570x1 for the sub channel

Aftermarket tweeter. Hot glued the front of the tweeter casing, really the only option i saw fit, and the glue can be peeled off if need be later

Headunit has differential signal output, so i had to tap into the stock harness









Speaker wires, rcas, 12v switched ran down opposite side of car



Box build (0.7 cubes sealed)









All hooked up

This looks really clean. Can you explain how you mounted and wired your tweeters? I have a '13 civic and will be replacing the fronts with Morel Maximo's. My only problem is since they have passive crossovers, I'll have to mount them in the door somewhere but I don't know how to get the tweeter wires down through the a-pillar, through the boot, and into the door. Did you have problems? Any advice? Thanks!
