helppp!! not new to car audio but stuck on this...

[annunaki]

ok i will seal the whole enclosure.. but what do i do about the receiever like you were saying? check my other msg i wrote what i have plugged in

Use the outputs from the headunit listed as subwoofer. There is no need for a y adapter here. The inputs on a mono amplifier are summed internally 999 times out of 1000.

Page 6 of the manual or page 6 of the PDF?? There is a difference.

The page in the link with the pictures of the connection has the number 6 at the bottom. One of us may need to update our reader, but the number 6 is right by the picture.

My reader states 8 as well. I was going by the actual page printed on the page itself. 6

ok so then my reciever is set up correctly then? so im running this amp at 2ohms now? i got the amp on 2v.. it just doesnt sound like its hitting much harder.. and even when i turned it up loud the vent was barely pushin out any air... the duals were pushing that air hard.. i dont know.. i followed everything inless sealing that top rele makes that much of a difference idk.. but ill find out thursday bcuz i work all day tomorrow but post back asap bcuz i will be on 2nite and 2morrw morning

Problem that hasn't been addressed. Why are the subs not firing backwards?

The box has to be sealed dude.

What about crossover settings? How do you have that set-up?

Also, as mentioned over-and-over, try a y-cable.

 

[annunaki]

That enclosure needs to be sealed, meaning the top glued on. Then you need to check the crossover settings on both the head unit and the amplifier. Once these are solved for we can look at a few more.

Also, you will not be able to feel as much air moving in the vent(s) because they are actually the correct size to keep the vent velocity low. Rapid air movement is NOT a good thing with vented enclosures as it adds noise and reduces output.

they arent facing the back bcuz the box is huge and i had to wait to paint it b4 i put it in all the way.. what will the y cable do? i will seal it tomorrow.. also what do yu mean by cross over settings? what should they be set to? on the amp everything is up.. n i had low mid n high bass alll the way up to it was xplod factory setting.. what else do i have to do how do i do it n wat is it set to?

ok also my friend has a box that has 2 rockford fosgate rfr-1812 12in subs in there and he wants to buy an amp.. and it says on the specs its 600 rms 1200 peak but its 8 ohms and we werent sure how that works since we cant find 8 ohm amps... let me knoow thanks

Enclosure design, installation, and setup are the primary keys to getting the most from any system home or car.

Start at the head unit first and use the manual. Please be sure to do these steps with the amplifier off.

Ensure that the crossover (if there is one) is set to off for now. Then ensure that the subwoofer level output from the head unit is set to maximum.



Then turn the amplifier back on. Next ensure your amplifier gain is set to minimum. Make sure that all of the crossover settings are off except for the lowpass crossover. This should be set between 80hz & 100hz or so.

Once this is completed, then with bass heavy music, turn up the head unit volume until you hear audible compression or distortion from the speakers. Back your volume down a little until this compression/distortion disappears. This is now the max volume setting. Then, with the volume at the max setting you just established, slowly turn up the gain on the amplifier until you hear slight distortion. Then slowly back down the gain until you no longer hear audible distortion.

Been involved in serious storms.

Been without power.

Missed a little.

Wondering how "not new to car audio" turned into "what do yu mean by cross over settings?"

Oh my!

As mentioned, time to actually open owners manuals and read them.

Forgot to mention that I am thankful my family is alive, and my property is fine.

Absolute wicked storm.

Then slowly back down the gain until you no longer hear audible distortion.

And then realize that the numeric number displayed on your head unit is reference level, and that you should never go beyond this point. If you feel you need to go beyond this point, more power is needed.

Glad to hear all is well with you & your family!!

ok well i have one last question. i have everything set up but the 4g ground cable is too short. i have 6g in my garage.. you think that wud be fine since im not running it at the full power 4g wires can handle?

I thought you had it going.

It has been mentioned how to do it correctly over-and-over.

It has been mentioned that you NOT try it before it's complete over-and-over.

And yet, you continue to insist on trying it out as you go along.

All of the correct information is in the thread.

Follow the advice that has been given.

I find it hard to believe that you took the time to build a fantastic enclosure, and continue to try to take shortcuts.

Do it right, or suffer the consequences.

4AWG power requires a 4AWG ground. Period.

i just didnt feel like going out an spending even more money on sum ground wires when its not my fault they didnt give me enough. i go it working with the 4g.
thanks

Who didn't give you enough?

You ordered a kit. I suggested you measure, and order bare wire. It's not someone elses fault that you didn't follow recommendations.

Measure twice, cut/order once. Just like the enclosure.

 

[annunaki]

So...

With everything installed how does it sound? Initial impressions?
