Bimmertech Amp no sound, please help

MelonKejepit · 01-06-2021, 10:06 AM

I bought bimmertech amp, and installed it on my 2007 e92.
The left subwoofer isn't working after i installed it.
I replace bimmertech amp with the OEM amp and the left subwoofer is working again, so i'm sure the left subwoofer is fine.

Just to be sure, I ordered a new pair of subwoofer, installed them, and the left subwoofer is still not working whenever it is connected to Bimmertech amp.
What could be the problem?

I've tried reaching out to Bimmertech but they only reply with switch the left and right subwoofer, i've told them the speaker is fine and they haven't got back to me yet.
I'm not pleased if i spent 800usd on an Amp that i can't use.

If it's new they should have some kind of warranty.
I would also hook it up to a computer and check the software
setting and maybe play with them.
I would try to troubleshoot the problem before you return it.
That means taking measurements .
Or possibly you could set up a remote session with them where they
could to the same.
What kind of speakers did you put in?

You need to specify which system you started out with and that
does not mean the head unit.
Specifics and pictures would help.
Where is TW?
Could the stock cars in your country be different than in the Rest of the World?
Check the wiring on the harness to make sure things are routed and connected
correctly.

I have a HIFI speaker system, TW is Taiwan but the car is imported from US.
It's a 2007 e92 328i with n51 engine.
I have bavsound ghost subwoofer, midrange and tweeters are alpha one speakers from bimmertech.
Every speaker works fine when i connect it to the OEM amp, but when i connect it to my bimmertech amp, my left subwoofer won't work at all.

Everything is working just fine if it's connected to my OEM amp, so i'm guessing the problem will be bimmertech amp.

I'll try connecting it to my laptop and check the setting tonight.

If it's not the setting I would guess Dead Channel or misswire.

What is a dead channel? Is it something i can fix myself?

Not unless you are and electronic technician and know how to read schematics
and have parts available .

A channel is one of the outputs or inputs.

As in I Have an 8 channel amp that has 8 individual outputs that are
connected to 8 speaker locations.
