Definately a grounding issue. check ground wire for breaks and make sure to ground on a solid metal surface such as the frame of the car.

Sounds as if you may have a bad ground. try running an external ground from the radio to a bare piece of metal underneath the dash.

I have a Kenwood KAC-9105D amp with 2 Rockford fosgate 10 inch subs in a sealed box. When i turn the volume up loud the bass fades out for a few secs and then comes back to being loud again, this keeps...


It's the battery, not enough juice to supply your amp at loud volumes so the bass will drop out especially on long bass notes. Replace your battery!

I have two 12 rockford fosgates p3 hooked up to and 350.2 kicker amp i just got them so i hooked them up and my amp will keep turning on and off


How may ohms are the p3's and how are they hooked up? Some amps won't handle less than 4 ohms bridged. Try running one sub to each amp channel.
Also check power and ground connections.
Useing too small of wire for power, ground can cause the same problem.

2 12 p3d212 2 ohm hooking up to a rockford fosgate p325 .1 mono amplifier can it work? and how?


Hello a_brake11,

The P325.1 is relatively small to power a pair of P3's. You'll only get 325 watts RMS at 2 ohms (162.5 watts per sub). The P3's power range is from 100-500 watts, so they will work, but don't expect them to be really loud.

For best power, your subs should be wired with the voice coils in series and then the 2 subs paralleled to the amp resulting in a 2 ohm load.

Hope this helps.

My kenwood kac-929 1000w amplifier is not powering my sub


unless you are a technician do not mess with the amplifier.
it takes years of school to learn electronics. unless it is a blown fuse or something simple,you will never fix it.
i did kenwood warranty for 8 years and the amplifiers are difficult to repair.

Connect rockford fosgate amplifier & speaker together


Assuming your P3 has a single voice coil (it will have only one place to plug your wires into) you will be running this in a bridged mode. You will take the left (+) coming off the amp and plug it into the (+) on the P3. Then take the right (+) from the amp and plug it into the (-) on the P3. This will make your amp push 500 watts to your sub. Now on the amp make sure your adjustments are as follows: Signal input switch is set to unbalanced for RCA input. Left Phase switch is set to 0. Right phase switch is set to 180. your X-card should be set to low pass. And adjust the gain for both R and L equally so it has equal power from both channels.

Subs not as loud as they should be plz help


RCA output level and speaker level output have different voltages and currents. The problem you are describing is common to folks trying to connect an OEM dash unit to an aftermarket amp. If your amp has speaker level inputs, try wiring to those......best bet..buy a new head unit, it'll sound better...louder and cleaner.

Buzzing bass Amp combo


The problem you have mentioned is a common one with old sets, but it also occurs in new ones also, though not frequent. You can fix this just by changing the electrolytic filter capacitors in the power supply and sub filters on the amp PCB. The new capacitors should be of the same or higher voltage rating and same capacity rating as of the existing ones. And as it is such an old one, it is better to change all the electrolytic capacitors to avoid any further problems.
