I have a weird problem..

[Tone415 10+ year member]

For some reason when i turn my volume up on the HU the bass gets quieter. for example, At 10 the bass is low like its supposed to, it gets louder at 15, louder at 20, lower at 23, lower at 25, lowest at 27, then cuts off at 29.

I have two amps, one for my door and rear speakers, and one for the sub. I have a PA A3000DB with a DD3512 D2 running at 4 ohms. gain is a little over half. Stock electrical.

This problem has never happened before, I've been running this set-up for about a month now. It "all of a sudden" happened after i changed my rear speakers yesterday. Tried to get as much detail for u guys as i could. Any suggestions?

I had this problem too - and I noticed it was because I tapped into old speaker wires to use a rca's since my HU didn't have 2 extra spots and this caused the exact same problem with me. It should't be doing that if all your rcas are in your HU, and your speakers are just sitting there with your speaker wire going directly from them to the amp. Did you tap into any other speakers wire?
