Well my very first set of subs were some company I had never heard of called verge and I had two twelves. They were horrible subs, paper cone, tiny magnet, not good at all. But even they had an rms wattage of 150. Try checking the ground on your deck too. I had a loud buzzing one time and it was because my ground wasnt connected well. Actually, check all your grounds while your at it. You want to make sure you dont just have them screwed down to a painted surface. Get some sandpaper if they are and scuff it up.

 

Good point. My head unit's ground is ziptied at the moment but it is touching bare metal inside the dashboard. I'm assuming it's getting it's grounding but I'll check again and permanently mount it somewhere.

My amp is grounded to one of the bolts that go up into the rear (third) brake light. Area around teh bolt is painted but I'm assuming I have a good ground there as well since it's bolted right to the thing, and the bolt isn't painted. Again, will check all grounds tomorrow. Perhaps will even get that ebay grounding kit if it helps.

 

A box doesn't take up a lot of room honestly. My setup is a pretty big box that's a cube. Slightly over 1cuft. I still have quite a big of room.

 

Nice sub. Space usage is everyone's own preference, really.

 

Ebay grounding kit wont help with that. I have it and it didnt really seem to do much other than my vehicle seems to be at a better charging rate while there is a load on the system. Probably a placebo though. The stock grounds on the car are very poor for grounding such high power items such as an amp. It should have its own dedicated ground IMO. And all grounds should touch bare metal, no paint even if the bolt isnt painted. Ya my decks ground was not fully secured and it buzzed really bad. I forgot about that. Ya make sure you scuff up even the bare metal where your putting your head unit ground. Just worth it in the long run and only takes like 10-20 secs to scuff it well.

 

i think i know the problem for the low bass. bring the LPF on the amp down to like 125 max. on your radio, there should be settings for specifically subwoofers. if so, you might have a HPF on your radio that is creating a "wall" that the subs cant go beyond. so see if you can take the HPF off for the subs on the radio. also, I know on my pioneer radio, there is an option that allows you to either select the rear output as full range or subwoofer. see if your radio has something like that and switch it to subwoofer. that way, your radio might start treating your subs like subs and not speakers lol play around with the radio some more, at this point, it cant be the amp or the subs.

also, if you have the time, DEFINITELY move the RCA wire to the other side of the car. usually, whine from the RCAs coming through the sub is hardly noticeable, but its usually there when next to the power wire.

and try grounding the amp to a bolt that holds the back seat to the chassis, if you have one lol

 

ok i just downloaded the manual for your subwoofer, and this is the best i can do over the internet lol

set your settings like this:
rear volume: 35
subwoofer level: +7
bass level: +2
middle level: +6 (although if you have stock speakers, try a little lower)
treble level: +8
balance: 0 (middle)
fader: Rear 4
front AND rear HPF: 120 Hz
Low pass Filter: 120 Hz
subwoofer phase: Reverse (180) (since your subs are backwards)
Loud: once you have all the other settings dialed in, try setting this ON and OFF and see which is better

without being in the radios presence and finding "hidden" menus, thats the best I can tell you. by "hidden" menus, I mean like on pioneers, if the radio is off, and you hold in the volume button, the settings menu comes on.

for your amp, set them like this:
Level: 2.5
Bass-EQ: 0 (for now)
LPF: 100 Hz
X-over: LPF
HPF: 40 Hz (all the way down...if this wasnt already all the way down, this may be why your subs wouldn't hit until you turned the LPF up!)

once you have these settings dialed in, along with the radio done, turn it on and turn the volume to 75% of the total volume. put on something with decent bass, a song in which you know how loud the bass should be with respect to the speakers. basically something you can easily tune the subs to. now heres where the playing comes into play, but ONLY USING THE BASS-EQ ON THE AMP AND THE LOUD ON THE RADIO!!! all the other settings on the amp and radio should be perfect. id say first turn the LOUD off on the radio, and play with bass eq from here. if that doesnt work out, to your liking, turn the bass-eq back to 0, turn loud ON, and play with your bass-eq again.

also, make sure your subs are wired right! i know one time i hooked the positive and negative up backwards and they sounded like absolute garbage. go into the box and make sure positive on each sub goes to positive on each terminal cup on the box, and positive goes to positive on the amp. same for negatives.

good luck and let us know. i strongly suggest at least turning your box around if you arent going to get a new one.

 

Wait, where did he say the model of the sub other than it was a jensen? Or did you figure it out? What model subs are they?

 

Here is my box. Evos don't have a pass through, so I didn't care about blocking it off. Plus, I took out my spare tire and jack and put a board under the carpet to support whatever I put back there. How does the bass sound with the rear seats folded down? I imagine a lot better then when they're up. Have you thought about cutting a port/hole into the rear deck and putting a grille over it and then firing your sub straight up and into the back glass?

 

Wow that's a lot and quite different from how I have it setup. I do have a few questions though.

You mean the head unit?

Are you talking about the 2zone feature? If you're talking about just volume, 35 is really high and my ears won't take that much.

My front stocks don't keep up with the rears as it is, should I lower them even more?

HPF-F and HPF-R right now is THROUGH because those, as I figured need to go to the speakers with full range. I suppose I was wrong and will try 120 for HPF.

LPF is also THROUGH because I'm handling it on the amp level. Should I keep it that way?

haha makes sense.

I've always liked loudness better, so I guess I'm keeping it that way for now.

Yes there are some hidden menu items from standby, last time my bluetooth got stuck I had to reset the head unit and I forgot to set those items. I can set things like speaker size along with other things I can't remember.

On the head unit you want 120Hz and on amp 100Hz. Just confirming.
If the switch is flipped to LPF, the amp disables the HPF control, correct? But just so if it doesn't, I always had it lowest.

Quote:

ONLY USING THE BASS-EQ ON THE AMP AND THE LOUD ON THE RADIO!!!

Understood.

Sounds interesting. From what I can understand, with these settings I'll be using mostly just the subs for lows and not my 6x9's, since HPF-R is 120Hz, gives more highs and less lows to my rear speakers, correct?

I'll give these settings a shot and get back with the results soon. Appreciate going all out for me!

 

haha yes sorry

i dont think so. i saw separate options for 2zone feature and rear speaker volume. this was just my personal preference to try and make the music itself loud, but if its too loud, thats fine lol

you arent lowering the fronts, you are making it so there is more rear fill. if you are still running all your speakers (even the 6x9s) off the head unit, they are only getting about 22 watts RMS anyways. this just gives it more of "surround" feel

is it LPF for the sub or speakers? if for the sub, turn it to 120 Hz, if for the speakers, keep it through

well then ive helped as much as i can with whats plain in front of me lol

right because the radios LPF options are 80 and 120 and some others, no 100.

yeah pretty much haha on second thought, try settings with this in the LPF spot and in the FULL spot

correct. you should never use speakers for lows, just mids. you can try setting the HPF-R to 80 if you want, which will add some bass (actually, mids) to the 6x9s, but also a little more distortion

good luck!

 

lol i meant his head unit, sorry!

nice setup, but really small port! lol did you build the box?

 

You have a lot of crap for one 10" sub... HUGE box

 

I assume hes running his doors off an amp and Ill bet that sub packs a hefty punch.

 

Ok I set everything to exactly how you asked. Then I turned up the bass on amp gradually. Eventually I was at 18dB but I had no bass from the speakers or the subs.... like almost nothing at all The only thing is, I can't crank it up to 75% volume, I have a sensitive ear and it hurts.

I'm thinking the subs and the box both are garbage. The only chance I will give this setup is sealing the ports and see if that makes it better. If all fails, I'll just use the amp to power my 6x9's and be happy with it.
