Switch it to 4 channel mode and just run 4 channels.
your rear deck free air speakers are subs....not midbass drivers. Midbass drivers need Relatively proper enclosures like all drivers. I recommended that amp because the 5/6 channels allowed a big delivery of power to the midbass Drivers
Yea I cannot get those kickers to sound good, they were supposed to sound decent as free air speakers.
When I switched it to 4 channel it should have made the front speakers louder but it didn’t. It seemed to have no affect. The bass knob also seemed to have no affect. The clipping lights didn’t work and it hissed.
I returned the crescendo amp and just hooked up a Rockford t1000-4ad and the hiss is gone and it just sounds better.
Crescendo may or may not give me full refund, i will see. I already took a loss from shipping costs.
I wouldn’t recommend the crescendo anymore until they get better.
Here’s an extra question:
We got that sundown audio sub amp and it has a LPF that can’t be turned off. I can turn it down as low as 30 Hz on the amp.
If i want the Subwoofer LPF set at 80 Hz, when i set it on the dsp should it be 80 Hz, or should I subtract whatever the amp is dialed in to?
So that it’s like 30hz on amp + 50hz on dsp = 80hz total LPF?
