It looks like your car doesn't have an amplifier. If it did the blue amp remote wire would be next to the green (battery switch) wire at the top right in the photo.

If I helped you fix it, why not...

Your support is greatly appreciated​

 

I just did a head unit, replaced all speakers, and added a sub. Unfortunately, the car already had an aftermarket stereo head unit with the wires spliced in. I just spliced the new unit’s harness to the factory wiring and turned the thing on.

I have the wiring diagram of the stereo with no amp so here’s the pin out:
1) BRN - LF + speaker
2) BLK > ORG > BLK - RF + speaker
3) ORG - RR + speaker
4) RED - LR + speaker
5) YEL - Interior Light System +
6)
7)
8)
9)
10)
11) GRN - ACC on 10A fuse left side of dash
12) RED - memory power 15A fuse left side of dash. Always hot
13) WHT - LF speaker -
14) YEL - RF speaker -
15) GRN - RR speaker -
16) BLU > ORG - LR speaker -
17) BLK/ORG - interior lights system -
18)
19)
20) GRY/BLK - ground
21)
22)
23) PNK - B+ (acc on)
24) BLK - ground


Important notes: there’s no remote wire because that’s the amp trigger (or power antenna when that was the rage). Gray/black is a ground. The other blue wire is the left rear speaker negative.

 

So is your car a GLS? I’m not sure if the SE has the better stereo option, but unless you have that optional stereo, then your car has no amp, and therefore it should work with just the output of the head unit.


Edit: Amp is located behind the right quarter panel, and on the sedan it’s located on the right front side of the trunk. There’s a 25A fuse for the amp, and the amp harness wire 9 is the remote which ties to wire 10 on the main stereo harness. Your pic shows that pin to be empty so you have no amp. If the stereo powers up but there’s no sound, then you have no choice but to re check your wiring.

 

Why did you cut the factory harness? Could have gone to local shop and gotten an adaptor or waited for a prime 1 day delivery, and get an adaptor. The wires are universal for aftermarket stuff, so you literally just take your radio plug, the adaptor and crimp red to red. yellow to yellow. Can even have your 6 year old do it. You have also now made it much harder to restore the vehicle to factory if that's what the next buyer wants.

I have provided diagrams for all sub-models and body styles of the accent of the 2007 year.

Here is the colors I forgot to add it, but I believe you already know them

 

Looks like you have an amped vehicle that explains the no sound
The first diagram 3Door AMP should work for you. Blue wire is amp turn on, the Gray Black stripe is a ground. Black with orange stripe is illumination negative.

Good luck buddy
