Rockford Fosgate P112-200 Car Subwoofer Questions & Answers
I have an sony xplod 4 channel 600 watt amp
First are they in the same box? If so and they are sharing the same air space running one amp to both is best andwill perform better. One woofer could be over powering the other and or you could have a woofer problem. A lso your wiring coul be problem. When amp is bridged it changes the OHM reading and output your other woofer may not be rated at or able to handle a lower Ohm rating also it coul blow that woofer if it hasn't already hapened . Be careful. check woofers independently for operation and check the non performing woofer on an unbridged power source or amp. Hope this helps. Write back if not.
When my bass hits, my car lights flicker.
Is the problem much more noticeable when the car is at idle? Double check that Alternator output. 70 amps is not high output, and if the problem is especially noticeable at idle, it's probably due to the alternator putting out lower voltage( a common thing with alternators). Also, with that much draw from your sub amp, the wire from battery to alternator should be beefed up, as well as the ground wire from battery. You can make up your own cables by purchasing the wire to length and wire lugs at a local Welding shop, 4 gauge from alternator to battery is good. High output aftermarket Alternators shoot into the 200 amp range.
When i play certain bass, like mainly highs, but
It is possible to overdrive a speaker beyond what it can handle.
DO NOT BELIEVE the spec sheets regarding power and capabilty, especially those for automobile amps and speakers.
If the cone moves too far, the voice coil leaves the active area of the magnetic field and the speaker will "rattle".
The speaker AND its enclosure may be resonating at particular frequencies.
If these things are happening, you will permanently damage the speakers.
2 12 p3d212 2 ohm hooking up to a rockford
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.
I have a Rockford Fosgate 1500 BD amplifier and terminals for the power cable will not loosen or tighten how do I fix it
First off will the fastener turn ? If not try using a bit of wd-40 and letting it "soak" for a little while . Also be sure you are using a good proper sized Phillips screwdriver . If the fastener still won't turn try using a can of "computer duster " inverted so the liquid comes out , note this will be well below zero degrees , and freeze the screw head , then try turning . If the fastener is stripped and the ttol slips you will have to remove the amp cover and grip it with a pair of vise grips ,pliers or a flat blade screw driver .
