Re: 2018 Nissan Leaf SV - Amplifier + Sub + 4 Speaker Replacement

True, I went and Picked up some cheap edge 6.5's they are 4 way and have max 50w RMS so existing head unit should be able to power them well. I pulled the existing speaker out and they are 20w 4ohm, quality wise they are terrible! I have started sound proofing the doors and hopefully this should be my quick fix for much better sound. I couldn't use the stock speaker bracket by cutting it out as my speakers were different but the nissan almera 06 front brackets are exactly the same part no. CT25NS01 by bass junkies connects 2. Will let you know how it sounds.

Right, new edge speakers have been in there for a week or two now and sound ridiculously good compared to the stock speakers. Still got an itch for that deep bass, just bought a line out converter and going to dig out my old sub and amp.

Can you show pics of how you connected to the battery? I was just curious because I read a different post about how there is a block of wire down the line from the battery. I just want to make sure I'm doing it right. Also have you seen any reduction in range?? Thanks for the great post.

The best way to connect to the battery and minimize questions is to connect directly to the battery post, not to the OEM post adapter. This way you don't interfere with any of the OEM fusing/circuits.

Can anyone tell me best place to ground from? I need somewhere close to the boot. I was thinking under the passenger seats?

Ideally, you would use the same size wire and the power wire and keep the ground as short as reasonably possible. Stay away from seat bolts and grind the paint away to get down to bare metal.

Thanks for the post - I just finished an upgrade of my own that was quite a learning journey for me not being a pro audio installer.
I like rock primarily but my wife and kids have different music tastes.

My approach was to keep the functionality of the head unit / hvac controls but improve the audio sound quality with a 4 channel amp plus new speakers for all doors.

Nissan Leaf SV (no Bose) with 7” lcd

I also intended to keep the upgrade as invisible as possible meaning no visible wires or obvious aftermarket hardware to get kicked or damaged when carrying stuff in the cargo area.

I ran a #4 power cable under the floor carpet and up through the firewall on drivers side.
Based on other forum posts I used the unused hole (plugged with grommet) to the left of where the hood release cable passes through the firewall.
Power wire is fused and connected to the + terminal.

I am using a line out converter (AudioControl LS2i) and taking the high level output from tapping into the rear speaker wires located in the B pillar.
I am using a 4 channel amp (infinity ref 704) to power the 4 Infinity ref 6.5” which I installed in all four doors.

Here are my outstanding issues which may lead me to reverse the install:

#1 issue - Apple CarPlay voice interaction is routed by the head unit to the front channel speakers only. I can’t hear it now, only faintly through the pillar tweeters which I left connected. This will not be welcomed by my wife who occasionally drives the car.

Should I switch my configuration to use the front channel as the source? Would mean time and effort but it seemingly would solve the voice interaction problem.

#2 Concern not an issue but I couldn’t find a good way to run the speaker cables to the front doors in a clean manner. Since I am using new speaker wire that comes from the new amp installed behind the rear seats I had to run the new wire under the front carpet and through the firewall then around the side under the foam gasket on the fender panel. Then through the rubber wire boot to the inside of the door.
Not ideal and looks bad.

Ground wire is connected to the metal bracket in the cargo area - bare metal with the paint removed from the connection points.

I haven’t done any tuning yet after hook up but it sounds good at medium to loud volumes but low volume produces no low end or mid range. This is likely something I can fix with an adjustment or by verifying all connections and solder points.

I may add a powered Bazooka tube once I get the other installed hardware optimized and working the way I like it since that would fill in the missing bass.

Overall I am pleased I finished the install because it was very difficult and I learned a ton.

# 1 lesson - Nissan didn’t think anyone likes decent audio or they want you to buy the Bose system which I couldn’t justify the several thousand dollar increase in price on top of the inflated cost for the 2018 model.

#1.b Nissan didn’t want anyone changing the configuration themselves based on how they designed the integration. I understand some of it but seriously? How much money do they save in sub par components vs. customer satisfaction?

Happy to hear input or feedback.

In my opinion, swapping to the front speaker outputs will make everyone in the family happy. It should restore the CarPlay (and maybe a similar issue with BT that's yet to be found out) functionality and may also help with the overall sound. As for the speaker wires into the doors, considering you skills, amount of power, and overall expectations, I would find where the speaker wires go into the door (in the cabin side) and tap onto them there. There isn't necessarily a risk of fire or destruction with how you've got the wires run now, but you might have an issue down the road with amp if the wire insulation wears and starts to short out the amp.

Everything else looks good. Good luck with your search for bottom end. You might have some luck with deadening the doors but it will be time/labor intensive and adding the Bazooka may be cheaper and easier.
