New fg box for idmax sounds muddy..

[Mopey 10+ year member]

I just installed an IDMAX sub in a fiberglass enclosure i built. I pretty much guesstimated the size, and it came out a bit bigger then i wanted. I know for an IDMAX, the enclosure shoudl be around 1 to 1.3 cubic feet. If it is a bit bigger then this, will it make the bass sound weak and muddy? If so, can i just secure something solid to the inside to shrink the effective air space?

When i have the head unit EQ on flat, and no base boost or anything, the sub is barely audible from the drivers seat...I'm not sure what's wrong. I reground at a few locations, making sure to properly sand, and tried grounding directly to the battery as well, all giving the same result. The sub will get loud if i turn the "loudness" setting on the HU up, and increase the base boost and all that crap, but i wouldn't think i'd need to. The base sounds shitty when i do that anyways. The cut off frequency is set to about 70 HZ.

Equipment:

Pioneer 780mp

PG Xenon 600.1

12" idmax

2 channel rockford fosgate

Rainbow SLC 265

Either your wiring for the sub is incorrect or your settings on the amp are incorrect. That enclosure will not make the IDmax sound terrible. Turn your subsonic filter all the way off and set your low pass filter to the max frequency. Don't turn bass boost on or any loud functions and see if that helps.

maybe check for any air leaks. They use to recommened 1-1.3 but then they started recommeneding 1.5 cuse it just sounded so good (I had mine in 1.5 and it was great) so that little extra space should be fine.

pics are small for you? they show up huge on my screen.

I took out the sub, and one of the wires was weakly held on, i rewired it much more securely and it seems to have helped. I also bought some t-nuts with bolts, and used those instead of screws, and cut down on some of the carpet, so the sub isn't seated on any. I'm going to set the amplifiers properly later today.

it might sound better with a little more watts. ~700-900watts would do well. Also an Idmax in a ~1.5 cbft sealed should sound great.
