Audio Nightmare! Need Some Help

Hey everyone, I've got a 2017 TRD PRO and was bummed it didn't come with a good sound system. I'm no audiophile but the speakers were definitely lacking.

I brought the truck to a guy and he ended up installing a HERTZ system with an amp and new speakers all around.

Unfortunately, I've brought it back to him 4 times. And on the 4th time he had an expert come in who works on exotics.

I don't know if the guy installed it correctly or what.. but the sound is just awful. When using the fade function on the head unit to isolate speakers, I put it in the driver's front and nothing is coming out of the speakers at all. The driver twitter is always crackling and sending out static-y feedback.

I'm sick of bringing it back to the guy and he charged me $1200 for the install and kit.. Can someone please help me out?

Is it possible the switches and controls are wrong on the back of the sub? I swear I tried every combination and everything sounds like garbage or just doesn't sound at all!

Help?

 

@manethon is a great guy to talk to on this.

 

@manethon if you have anything you could contribute, I'd really appreciate it

 

So all this hooked up to your Stock Head Unit?

 

So how many channels is that amp? Do you have Subs?

 

It's a HERTZ HCP 4 Channel amp. I don't have any subs

Yes it's all the stock head unit

 

I believe to hook up an aftermarket amp to a Stock Head Unit the amp would have to have speaker level inputs and I am not sure it does. Hence the ability not to fade

 

I wish I knew.. all I know is that the cords from the head unit are plugged into the amp where it says HI IN (front and rear)

 

If it helps.. this is what the rear looks like without a horrible iPhone flash

 

Hmmmmmmmmmmmmmmmmmmmm

 

@Mr Marv would you be able to provide any input?

 

Who's that? You mean @Mr Marv

 

It’s going to be hard to troubleshot over the web. That system should rock, had Hertz in my last truck, good quaility stuff.

 

That's what I was afraid of.. might just bring it into a different shop and have them take a look

 

Unfortunately the guy before me did a similar hack.....I ripped it all out and required all the speakers to a new head unit.

 

Any idea what the guy did wrong?

 

Do you have more pictures of the wiring or connections?

 

These are the best I could get.. the only pictures I could get of wiring were the connections of the amp

 

and these are the layouts of the front/rear of the amp

 

From the pictures it looks like the shop does good work. It sounding like shit doesn't fit the install pics.

Does your truck have the JBl system in it?
