Highs or Lows

I installed one of these in my car between my head-unit and 15 band trunk EQ to stop engine noise i was having. After installing and turning on my car engine i was the happiest on the block, all my engine noise was gone, my mids and highs lit up my neighbourhood.
Con: My subwoofer was no longer recieving sub frequencies!!! So i was left with no engine noise and no bass.

Great Product!!

The product has a very good price for what it does. It came to me in a very short amount of time. East to install, no issues at all. Has been working ever since.
Again, never look for things like this any other places than Sonicelectronix. Don't waste your time in any other stores.

It worked

I installed a Car PC and it was plagued with all kinds of noise due to many ground loop issues. I installed the B25N before all of the amps and now it is totally silent.

The resulting dynamic range is amazing.

Works as expected!

It's a simple product, bu it does what it says. A little large, but has some mounting holes, which is nice. Worked perfectly.

Does the job at a great price

Needed to get some noise out of my Preouts and these did the job perfectly. A little bulky but work well
