Diirek, thanks for sharing this install and details. I have been following your thread for a while and I think this will be my next project. I am not much of a basshead and while HK sounds mostly fine, at times I have felt the need for a little added lower end so hopefully this sub, after breaking will suffice. My only condition, that I will check before installing is that the sub should fit inside the donut spare since I have one.

Thinking of going with Rockville V2 to keep costs down. I have a couple of questions.

1. Does the harness provide power to the sub?
2. Connectivity to sub with the sub harness looks easy enough but would you be able to show how you mated the harnesses together?
3.Did you go with low level inputs?
4. Any other tips or gotchas to watch out for?

Thanks!

No problem!

1. No - The sub needs a power source connected directly to the battery, just like an aftermarket amp install. I believe the rockville sub came with everything though. Comes with a power wire with inline fuse, ground wire and low level RCA cable.
2. Piece of cake - The technic harness intercepts the the factory harness at the amp and wires into the wavtech low level converter. This is also where the remote wire and RCA's connects to/from the amp/sub.
3. Yes
4. Not really - One of the easiest installs I've done. There's a remote to adjust gain, etc. that comes with the sub that you're supposed to run up front. I adjusted everything to my liking and tucked the controller in the trunk with everything else.

Nope. The blue wire is the remote on switch and connects from the LOC150 to the remote on wire on the sub harness. It’s really easy to see when it’s all laid out in front of you.

I see. And the black jacketed wire set next to the blue wire… did you jacket those? I got the harness (not the sub yet) and I don’t see that set in there…

For the most part I was able to figure out the connections looking at your pictures and comparing the harness but that black jacket wire set going to LOC has me confused:)


Edit: I notice that at the other end of that jacketed cable, you have the green/white speaker wires and red black power wires all going to the harness in the same white socket (3rd image, bottom connector on harness) - In my package I have two separate white sockets (White/Green and Red/Black) that perhaps need to be combined?

I didn't jacket anything - The kit came like that. Did your kit come with install instructions?

Technic rarely responds to email. It could be over a week before they reply.
I would never use Rockville wire for my installs. You get CCA and very thin wires.
I bought two Rockville sub wire kits back in 2019. Looked at and it's fukno!
Cerwin Vega spare tire sub manual says if you use CCA (Copper clad aluminum) for power wires, your warranty is VOID!

They responded promptly and exchanged multiple emails to explain that now they offer 2 wire solution like I received. For power to LOC red/black wires should be connected directly to sub’s amp/ car battery connection so RAM doesn’t get messed up. Fair enough

I have plenty of other heavy gauge wires left over from multiple home audio projects so not concerned.



On another note, I have a spare wheel in the back that’s just sitting there (not anchored). I didn’t see any hole under center of the wheel well carpet to screw down. Anyone knows if there is a nut under the carpet to anchor wheel/sub?

Completed the install of the Rockville amp last night. Wiring was all straightforward and took barely 20 mins, thanks to Diirek for posting images! I ran into an issue where the amp or the LOC wouldn't power up so had to get my multimeter out to test wires. It turns out that the 1amp fuse in the Technic harness was bad (although visual inspection did not show any issues). Jumped it for now using a single strand of wire and ordered a bunch spares on Amazon.

The amp sounds pretty decent without breaking in - I have kept it at low gain to break it in over the next few days and tuned it using some songs. Once its settled I will tune it properly using Sound Pressure Meter and test tones.

The sound is continuously getting better as it breaks in - tighter. How did you guys tune yours? What' your cross over at ? For now mine is set to around 80Hz , gain at 11 o'clock, phase 0 and no bass boost. I lowered the eq in the head unit for anything below 100Hz to 0.

How has it been now that you have had it for awhile? Are you still using the Rockville? I am interested in going this route as I would like just a little more bass but keep things stock looking.

do you have a spare tire or are you on run flat tires?
