Sub control is 100hz +1 -12

Sub is obviously on

HPF setting is 100hz

Bass boost is 0

EQ is powerful

SLA is +2

Balance and fader are both 0, untouched

I had an additive audio version 4 12" and I kind of learned some stuff with that but I'm still new to car audio and audio in general. I know the basics and some trouble shooting but not much beyond that

If you use the decks crossover ..you can set the sub crossover to flat on the amp or bypass ...set the deck at 80hz for subwoofer...turn crossover off on the amp...you dont want 2 crossovers (amp & deck) because they most likely wont match plus your slopes and phase start going out of whack

If its fiberglassed wrapped it should be pretty durable...but 1/2 by itself would flex and cause weird noises in sound...I do a mine out of 3/4 MDF or Birch

It was a box I got at best buy which I know is not the best but it was cheap. Probably why it doesn't sound good. I had a huge box that weighed easily 15 pounds it was 7/8" MDF with a port big enough for me to fit my whole arm up to my shoulder haha. 3 cubic feet of inside space

Is the deck cross over a better way to get sound or the amp crossover?

Plus my back seats prove to be one hell of a muffle causer

Your EQ should not be at powerful Keep it at flat and rest your gains again its completely set wrong and the EQ will screw up your bass and kill your subs All bass frequencies should be flat. Anything 80hz and above on the EQ can be tampered with to get the sound you want but anything underneath that frequency is forbidden. SLA should be at 0. Low pass filter on the amp should be wide as in the higest it can go. You want to use the low pass filter on the head unit set to 80hz. Low pass cuts off the frequencies above so it blocks out vocals from the subs. However, if you set it too low like you have with your amp ATM, you are missing out on all the kick drums aka midbass from rock and metal.

Gains should be reset set again properly after these changes. Volume knob on the head unit should be as high as your speakers can get without distorting. Then play a bassy song and slowly turn up your gain. When you hear the sub start changing to a different pitch, then you need to back up the gain a bit. OR if it stops getting louder, that means you are at clipping(dangerous levels) back it down slightly if that happens.

15lbs is not much for a 10 inch box. That box you have already looks too small to be honest. Pre-made boxes are generally garbage and they lie on specs all the time.

If you hacve the ski (beer) hatch you can fold it down like an armrest all the time...I did that in my Mercedes CLK and removed the plate that was behind it ...It made a big differnce ..

he folded down the seats and didnt notice the muddiness peaky bass go away. Its his whole system tuning going out of whack because of his EQ boosting the 50hz peak way too high. Thats what the "powerful" setting does. Along with killing subs for breakfast.

I really appreciate the help but do you mind telling me what to do in "stupid" form? I'm kinda new to this stuff and don't know all the lingo yet

Thats the same deck I have to check out for a friend shortly...He said it just started getting a whining noise...I hope they dont have pico fuses but it sounds like the problem from the description...//content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif

EQ change from powerful to flat then go to custom EQ and see what does what and play around with it to get the best sound for you, just remember not to boost too much. Do not fk with anything that changes your bass output or sound in the EQ options set those to zero/flat.

SLA - set to 0

low pass filter (located around subwoofer options) - set to 80hz

Sub level - max

Head unit volume - high as your speakers/ears can handle without distorting.

Play a rock song, go back and turn the gain up until the bass doesnt feel like its getting any louder. When it gets to that point, back it off slightly.

So basically what you're saying is turn SLA off turn bass boost off turn sub control to 80 or 100hz turn HPF to 80 or 100hz turn EQ to flat and turn the volume as far as it can go before clipping/distortion and readjust the gain level, turn cross over level as far as it will go and turn off bass boost?

I checked out kickers specs on the sub and it says at least 1.5 cubic feet of space to work "properly"

yes to all that. Use a rock song to set the gains again to get the appropriate output. However if you play bass heavy music or hip hop, you need to turn it down since bass in recording levels are different and it directly affects the amplifier power output. Same concept, if it stops getting louder, back it off.

yup, kickers need big boxes.

So get a different seal box. Hahaha. In the sub control menu I can set the hz level, then the next set is sub boost or volume? Like -1-2-3 +1+2+3, set that to the highest? Or keep it at 0?

Thats called a subwoofer level. Dont worry, its not a bass boost thats actually gives you the proper pre-out voltage signal you need. It does not distort the signal by adding in bass that is not there to begin with like bass boost does. It helps get a strong signal to the amp so the amp can output proper power.

In short, set that to max,

You can try adding polyfill to the box if you are on a budget.
