No sound from Subwoofers

I have a iva-d300. i also have aftermarket subwoofers and mids. i have Rockford Fosgate subs and amps and MB quart mids so they r not junk. both on Rockford amplifiers. i have all of the wiring correct and my mids work fine and i have power to my sub amp. i went thru the manual and im positive i have done everything it says to do.but i have no sound at all coming from my subs. im not sure if there is a hidden setting for the subwoofers in the head unit or not???

Did you check the gain level on the amp? Sometimes a bad or loose ground can cause this also. Was it working previosly and it stopped or did it never work at all. Let me know. Hope this helps.

Hi, Make sure the connection are correct + to+ and - to -.
Also make the same connection to your amp + to + and - to -.
Make sure that your amp can run the subs, wattage and ohms.
Hope that helps.

What settings to put on Rockford fosgate Prime 250.1? one P1 12 4 Rockford Fosgate speaker, in atrend LSV 12 vented box. With JVC radio that has the sub woof, MID. What is MID and what setting to put it...

Need to know what JVC deck you are referring to so I can give you optimal settings. Mid is the mid-range of frequencies... ones that are sent to your door speakers' woofers, not the sub-woofer. So set that to whatever you feel sounds best, probably low in my opinion. Subwoofer set it as loud as you want, it depends on what kind of music you listen to. If you want your bass to be "boomy" then set it high. If you want it tight and crisp set it low.

Auto adj is auto adjustment for when you turn the sound louder it increases all settings accordingly. I always recommend putting that on 5 so if you ever want to crank it - the whole system gets cranked.

Thanks, let me know if you have any questions or concerns, just reply to my answer here and I will be right back with you.

Why does my 6x9 amp drop or not let the sound play at all when my subs are on? it just started to happen? they worked together fine before. i turn the subs off and the 6x9 work? but when i turn the subs on...

You probably have too much hooked up for the size of your power supply which is presumably a small car battery. You either need to get:

A) New, better bigger battery.
B) Capacitor in series with battery.
C) Both of the above.

What are the specs,rms ect on my older mb quart psc 216 speakers

Any type of 4 channel amp that will allow the speakers to be hooked up at 4ohm. I would check your local walmart. The brand VR3 are made by Rockford fosgate as well as lighting audio. From what I have heard they are some really good amps at affordable prices. If you are looking to spend some money I would recommend a JL Audio e2150

Rockford Punch HE2 wiring question.

if your sub will handle it, bridging it will give you more power. The best thing to do is to find out how much power the amp puts out ( RMS ) and if it is in your power handling range bridge it. It sounds better and gives you a harder punch because of more power.

Wiring

You may be surprised to learn that even though there is a negative and positive on the sub it usually dont matter all that much because that amp allows you to switch the polarity of its outputs to allow your mids to sound better... anyways on to your question To wire a sub it depends on how many you have, if they are dual or single voice coils, what impediance your amp is stable at. Tell me what type of amp you are hooking this subwoofer up to and how many are being connected. And ill try and give you the best way to connect the sub(s) to your amp.
