2018 Sound Upgrade Problems

We've used this as our LOC unit in 2018 installs

LC2i - AudioControl

What leads did you tap into for the stealthbox? Stock sub leads? Did you leave the stock sub?

Any update on this? Looking to upgrade my 2018.

I would welcome updates as well. Looking to upgrade my 2018 sound system.

Thank you

I have a 2018 with a Stealth box and JL 600-1/V3 amp. I don’t have a PAC or LC2i - AudioControl its just the sub and amp somehow connecting to the stock B&O system. 2 days ago my amp went out, so i thought ok maybe its a fuse. I took it to the shop, and a fuse was indeed blown. They replaced the fuse and the amp wouldn't turn on. They tell me it looks like a bad amp. So the shop gives me a replacement amp until they can get me a new amp. They put the new replacement amp in and it turns out the sub in the stealth box also blew. So two of JL's top components blew up at the same time. The shop i took it to had no idea what the issue was, they just told me they need to have JL evaluate the bad component to find out why both failed at the same time. Can any experts here tell me what the root cause might be? To me, it looks like an installation problem. Is a PAC or LC2i needed to tap into the B&O system?

Following. As far as blowing both, that sounds strange. Do you run your audio system hard? I wonder if some distorted signal went through and blew both components.

Not at all my old ass ears can’t handle hard anymore. The bass knob is turned all the way down on most songs. I will say this combo puts out some serious bass.

By no means am I an expert, but did they run power straight to the battery for the sub amp?

I'm not 100% sure but yes it looks like they ran a 4 gauge straight.

Also, where did you install the crossovers for the front speakers?
