Polk DB651's on a 4 chan too loud??

[microhaxo 10+ year member]

This is going to sound crazy but, i bought all new speakers for my new car, installed them and decided to go with a 4 channel instead of deck power. I bought an MBQuart ONYX 60.4 and i began to tune the amp. The speakers i have are rated at 60w RMS for the fronts and the backs are rated for 50w rms each.

With the deck completely flat, I am not kidding when I say that I couldn't turn the amp past 7.8 volts..

For those who dont know, that is 15.21 watts RMS to each speaker.

THE VOCALS WERE EAR BLOWING

How in the HELL could you ever even get close to 60w RMS let alone 25?????

That being said, the mid bass from the 4 channel was much weaker than when when using the deck. I was completely surprised by that.

i think you have a quiet definition of loud.

im going to be running right at 800rms to my new front stage.

it's called an EQ, man

I would need to lower the high frequency range by atleast 6db if i wanted to run at 40w rms.

check the HPF on the amp, that could be blocking your midbass, not that those mids will give you much.

x10 on your definition of loud as I run a few thousand watts on my front stage...

 

[microhaxo 10+ year member]

The amp is running them FULL, the deck crosses them at 90hz.

just start working with the eq. and possibly turn the volume down if you ears still cant handle it.

 

[microhaxo 10+ year member]

I have the volume at a great level, i just have zero mid bass. I have a sub that can fill in the lows but the mids are pretty much non existent.

 

[Phoenix Risen 10+ year member]

sounds like you got the wrong component set then.

 

[microhaxo 10+ year member]

guess so, i expected the 4 channel to push them more than my deck thus making more midbass, the deck actually made twice as much flat. IDK..

They sound good so i'll live with them.

if you do decide to replace the mids look into the silver flutes that are on madisound/partsexpress.

they are tough to beat for the price.

 

[microhaxo 10+ year member]

Thanks, ill look into them.

Turn the amp gain up until the midbass is at least as strong as it was with the head unit power. You're still doing something wrong.
