Just out of curiosity, how is your Basslink tuned? Where do you have your gain adjustment and bass boost set at?

I connected it to a battery I had laying around in my garage. Basslink worked perfectly

I then directly connected it to the main battery. It keeps cutting out.

Voltometer says 14 coming from the main battery without the car being turned on. I burnt a fuse and tried again but still no results. I tried with car on and off.

Voltometer said 12 when I connected it to the outlets in the green box. No results.

The problem is coming from my battery since it worked perfectlty with the other battery I had in my garage (it is from a maxima).

Update: For the hell of it I added capacitors to the speaker wires. No change. Still cutting offf.

Buy a new battery?

Any suggestions what is wrong?

I figured out the problem ..

It looks like I used a 12 gauge power cable.
If I replace it with an 8 gauge power cable it should work

Still puzzled as to why it worked with the battery that wasnt in the car.

If you can, go with the biggest the basslink can take (I think it's a 4 gauge). The amp will have an easier time getting the power it needs.

I had a Basslink in a wakeboard boat, hooked both the power and the ground directly to the battery (8 ga cable) and never had any issues with it cutting out. I think you need to bypass that green box and go directly to the battery - should be easy considering the battery is back there too!!

Good luck!!

The person who installed my basslink sucks: I just looked at it

The speaker level connections were cut and reconnected with the sub. There is a capacitor (mini one) on the wire and I was wondering why it was helping. The wires are not solded! The guy just twisted the wires.

Now I dont know if that is the problem or not?

Another thing i noticed was that when he cut the power/ground cables that half the wires are sticking out when it is connected. I asked him and he said it doesnt make a difference as long as all the wires are touching. The wires are curled up and going all over the place.

I am using an 8 gauge wire cut to 4 feet.

I still dont understand why it worked with the battery I had in my garage and not on the X5 (I connected it directly to the battery).

Hopefully the wires are just messed up.
This whole time I was just the tester and my installer was the one in the back doing all the work. My job was simply to suggest new ideas to him and turn on the radio when he said go.
