Default C7 Vert build

Finally got the energy to get this started. Learned a lot when I did my C6 coupe and have applied that here.

System design: (to be uploaded later)
Door upgrade with sound deadner and 10" Kenwood for sub/midbass. The midrange will be an Infinity perfect 300m.

10 inch fit without a baffle. Deadner in inner and outer skin. I love midbass!!

Driver door
sub box coming soon @madsonp

Lots of angles on the C7, plus a bit less room than the C6.


Not making the final angle cut until the L8S are mocked up. UPS is late!!!

Simple amp rack in the trunk.

Updates coming tomorrow.

You've been busy, it’ll be interesting to see how everything turns out when you get it all finished.

Not sure how you were able to fit the L7S subs in there. My box came out massive. I need to redo it. I might even have to go with the T series instead.




Full view of amp rack.

Huh, yep mine fit but it’s tight, are those the 8” speakers ? How does your box sound ? Looks like you got more box volume than mine has. Does your top open and close without any issues ?

yes, 8" L7S. Troubleshooting issues with the PAC interface, so no sound yet. No problems with the top.

Finally finished up the tuning (by ear). It sounds insane. Those Kenwood 10" door woofers are solid. Almost don't need the 8" solobarics. Tuned everything without the 8s and I was very happy. I then dialed in the 8s and could not stop grinning and feeling ridiculous.

I still need to figure out why the system does not turn off. My meter went out to lunch, so need to fix that first.

So did you change the sub box design any ? Can’t help with the system not turning off, I know nothing about the C7’s.

No change from the picture that I posted previously. That's a change that is down the road. Once I fix my meter, I will know if it's a problem with the pac interface or the dsp.

It’ll be interesting to see the final product when you get everything done. Does the tonneau cover close without any issues ?

Well if you get the sub perfected, you know you might have to get into manufacturing them for the C7’s.

yeah. Feel like doing a mold and then making it out of Fiberglass. Just for those that are worried about the extra weight.
