Speaker wiring system

I’m usually pretty good when it comes to who puts their hands on my truck. Got injured at work my brothers friend said he can hook up after market speakers with a new aftermarket radio. No biggie right. I decided last week I want to change things out again due to one side always cutting out. I’m reading on line there’s speaker wire harness that plugs into the factory wire harness. I pull my front door panel off and the dude cut off the harness ends and just ran the speaker P n N to the wire! He cut all of them except my tweeters in the dash. What to do?

 

go cut the guys nuts off, then tell him about these: http://www.metraonline.com/part/Toyota_Universal_wire+harness_72-8104

 

Am I reading that right. you have one side that cuts out so you want to change things? Did he install an aftermarket head unit? How did he connect the speaker wires? Is it red butt connectors? Sounds like the connections are weak. Maybe not a bad thing he ran new wire...maybe should have done better connections.
I would ask him how everything was connected then just start lightly tugging on them. I bet you get the ones that cutout to separate.

 

Thanks guys, my truck is the SR5 it didn’t come with GPS n Rear camera yet Toyota prewires it. I bought a plug n play aftermarket headunit, new door speakers and a amp with 2 12 subs. Lately I noticed the passenger side would cut out when it was on for a period of time, that’s when I investigated. I think it may be the amp. It has 2 RCA inputs but not a R L input like the headunit. I unplugged the RCA at the amp only one channel is working suppling all Door speakers n sub. I don’t know much about it, I do know he cut the dam harness ends off, thanks I appreciate it

 

Yeah he cut the end of the harness off that plugged into the door speakers. He ran positive n negative to the two wires pink that fed the harness. I had good sound for a year it just started up with cutting out. I don’t think the amp is wired correctly. I bought a new amp it will be here tomorrow I’m just worried about him cutting of the harness plugs

 

Also reading the forums Toyota uses high n low voltage 6 n12 v in their systems that’s why like the tweeters have 4 wires to the harness etc. I know you’re not supposed to cut those harness off n that’s why they sale the speaker harness adapters. It could be why the amp is only working on 1 channel now it fired it. I don’t know what to do with this thanks again

 

Cut the wires.

all of them.

 

Lol n just put in a boom box

 

Ok. Now I get what your saying. Sounds like you may be getting into a can of warms. If you are replacing the amp and you think it may be wired wrong it might be worth it to grab a friend and a meter and start from the headunit and work your way to the doors. Make a list of everything you need to replace and just do it that way you know it is right.
Hope your wiring isn’t too jacked and you get it figured out.

 

I appreciate it will do

 

It would suck, but I would plan on replacing all speaker wire with heavier wire. Not really needed unless you are putting in a Booming system, but you need to replace everything he touched. No idea what he butchered under the dash or behind the HU, Do it yourself and you know it's done right.

 

I checked all the wiring didn’t find any problems except for ground wire to the amp, moved it made it longer it’s fine. The problem now is the amp works fine with headunit n power on, but as soon as I turn the engine on it quits working, turn the engine off it works fine. Doesn’t blow any fuses nothing. Anyone know the source of the problem

 

Remote signal hooked to wrong wire? Loses power once ignition switch is released maybe.

 

I checked the remote wire is fine, could it be the deck? There’s a huge delay when it’s turned on there’s a Toyota icon that comes on the screen first before the radio turns on, the amp turns on immediately before radio it also shuts off last after the radio turns off. Would a delay relay work to solve that. Maybe some of the other items that turn on like the camera uses 6 volts this is new to me thanks
