install aftermarket amplifier on Kizashi base without Rockford system

[Satya166]

Yes not a pro but have worked on my motorcycle electrical circuit.
Will open up the trims and let you know sir.

From the diagram I can understand that the signal for centre speaker is spliced and given to the door speakers.

If centre speaker is working that means the head unit is giving signal correct?

[SAEED_KIZZY]

that's correct. Keep in mind that because all left or right speakers are spliced from one wire problems in one speaker can cause other speakers to fail too.

hi aranciata-oz,

as you can see in below schematic 2 wires are used to send subwoofer signal from HU to subwoofer: GREY and GRN/YEL

I replaced OEM headunit with aftermarket android unit(ATOTO A6) and also use Kenwood amplifier so I cut these 2 wires and send it to Kenwood amplifier which I placed it on OEM AMP spot(which you can see on my previous post) and send it back to subwoofer.

In 4 channel amp I used same process, RCA output of my HU and send it Poineer amplifer and send it back to my HU and connect those wires to OEM connector (G248)

I am receiving 12v at all the fuses

But my amp is having a fuse rating of 80amp.

If I take 4 parallel connection from.the fuses and combine them and then put a inline fuse of 60amp for safety will it work?

Is it a good idea.?

bad idea fuses are safety components you can not use them in parallel. for 80A use 3 Gauge wire directly from + battery terminal also use a 100A fuse at the battery for safety.

From which side is the entrance through fire wall ?
I don't want to make additional holes in the firewall.

If I remember correctly my amp was not that powefull so I tap into fuse on junction box no.2 but after a while I decided to buy OE amplifier and use the same power for that so I did not need to use power directly from battery but some folks said we can use car oe wiring harness beneath steering whell use this path to route cable but I couldn't convince myself to do that.

Thank you
I'll update with what I do finally
I first tried to fit the amp under front seat but there are wires beneath which doesn't allow the amp to slide in
