I have a Rockford Fosgate P3D4-12 and 4 Kicker 40CS654 6-1/2" 2-way Speakers. With a PIONEER GM-D9601 and PIONEER GM-D8604.

I am experiencing mild distortion during certain songs in my door speakers when I turn the volume up in order to compensate for my subs volume. I have the HPF set as high as it goes on my speakers but distortion still occurs.

What are my options to eliminate the distortion?

Also, I am experiencing muddy bass notes when I listen to metal because of the fast bass notes.

How can I fix this?

I thought of possibly adding a few 8" subs for mid-bass notes. Along with adding a crossover. Will these help with my problem?

your over pushing the amplifier on the top end , when it starts to distort turn it down a bit
...your high pass filter is most likely filtering out all your mid bass if it's set that high
the 2 way Kicker coaxils will not produce impressive mid bass
if it was me I would spend some money on good components for the top end
and build pods so you don't have to have the HPF set to the roof
..this will fix your mid bass problem and give you WAYYY better sound quality

as far as the sub goes..if it's muddy your enclosure is probably out of wack, I have
installed many P3's and they are tight in the right enclosure
if you add more subs you will still have that muddy bass in the back ground

don't add more to the problem...
find the problem and fix it properly and you won't be dissapointed

Thumpper,

Okay, I will get some new components. Instead of pods, what about the factory tweeter locations in the dash? And I don't see how I am over pushing my amp when it is is rated for 100 rms per channel and my gains are set fairly low. My enclosure is a Belva MDFS12, which is 1.0 CU feet. What is wrong with this enclosure? The bass notes only get sloppy when they are very fast. I wanted to add the 8's to use for the higher range bass notes, so that I could lower the LPF on my P3. I agree with getting some new components, but I thought that id I set a HPF and LPF on a pair of 8's they would play those double bass drum notes. Have I heard incorrectly?

I modeled it , you have 1.006 cf3 of effective inner volume after displacement




it doesn't look that bad for sealed ,I would say turn your low pass filter down slightly




as far as the top end ,,,, some nice sealed pods for the mids will improve
mid bass and power handling , try and keep the tweeters close to the mids
and sound deaden the doors

I do not have the tools to create my own pods. Is there some sort of pod kit I can buy and install?

p.s. thanks for the direction and advice.

pods are not that hard.... a few rolls of tape , resin and matting
the only hard part is cutting the MDF rings and placing them for staging
take a look at my build log in the enclosure section for the 12" Icon enclosure
I use a hot glue gun to put them in place

you might be able to find someone local to help....

I'm bouncing my mirrors with the mid bass from my front stage
with a single pair of 6.5" components... I love sealed mid bass pods

Bassnoob

So that's a no on any prefab pods?

And I'm new to navigating on this site, how do I view your build log?

Bassnoob

Nvm, I found it. What would the materials cost to build those pods? Also is there a more detailed step by step on how you did that? Or possibly a vid? And would a dremel tool work to cut the mdf rings?
