Audio Help; LC7i install

Hey TW, seeking and hoping I be able get input on my project. I'm not new to the audio stuff or modding in general but haven't be able to find a solid answer on this. I've reached out to AudioControl as well and awaiting their response.

Back ground, '18 OR non JBL system. Keeping the Entune HU. I've already swapped out all the speakers to kickers. Wire harness acquired from ********* for speaker level out to the component and back into to factory speaker wiring to cut out the need to run new wiring, will be running my speakers below 75w RMS. Putting in my stealthbox I had from my 2gen along with a Alpine PDR-V75.

The LC7i requires a max 2 amp power feed. Question about how that can be achieved. Is it ok to get the constant +12v from behind the headunit wire? Or do "add a fuse" at the radio fuse? I know I can run an inline fuse directly from the battery but since the amp draw is so small, why not get it from another location I believe is OK to work with. Are either locations sufficient enough for the LC7i to operate with no ill effect else where all the while reduce and have one less thing connected at the battery terminal under the hood.

 

Perfectly fine to get power wherever you want. In most cases, the LC7i will be located near the amp due to its size. It’s not a small device for sure. If it’s located next to the amp, grab power and ground from the amp.
If it’s located behind the radio somehow, you can grab power and ground there.

 

Thanks for the input. I read that some people were getting a popping noise when they initially power up their system. Is that due to the power source and or ground source they could be using?

 

There are lots of things that can cause that. I’ve learned to never worry about turn-on pop until you actually have it. You’ll drive yourself crazy trying to avoid every single problem that can happen.

 

@destin_meeks appreciate the input. Gonna do add a fuse at the fuse block using the radio fuse location.

 

Stupid question. If you need to run power from the battery for an amp anyway wouldn't it be easier to use one of these and tap off of it to power both the amp and the lc7?

Not a stupid question. You can absolutely do that. Although one of those is overkill. You can run the lc7i’s power, ground, and remote straight to the amp. No need for a distribution block really. If your power wire to the LC7i is only a few inches, it’s all good. If it’s a few feet or longner, that’s when fuses get introduced.

 

So power line (80amp inline fuse) straight to the main amp (2/4/5 channel amp) and to give power to the LC7i (2 amp fuse needed) it's ok to just wire the LC7i straight up if the units are next to each out with no inline fuse for the LC7i or inline fuse is still warranted due to 2 amp rating of the LC7i?

 

straight up is fine. the fuse is there to protect the wire, not the device. so when dealing with such a short wire run, there isn't enough wire to be worried about.
If you are concerned about it though, grab one of these and it will make you sleep better at night
