SPL 1920 watt amp

I have that amp right thurr, trying to hook it up to 2 memphis 12 subs in a vented box. before this i had a rockford fosgate 325.1 hooked up to it, and it worked fine. When i turn the car on after everything is in, all i hear is bass just going on and on and on... i can change the channel on the amp and i can get it do several other patterns, but i can't get it to just play with my music... the bass boost is all the way up, i don't know that the frequency should be at, and the volume on the amp is in the middleish... can anyone tell me how to make it work?

For 1 never turn the gain all the way up. it is not there to control volume it is there to match gain impedance between other amps and components. 2 i dont know what amp you have so i cant say much about that. 3 test the rca inputs by using a dif set and test the speaker wires as well

Does anybody know what watt this is. it's sosed to be a 2400 watt and why does it have 2 ports on each side to hook up speaker wire And what's the best way to run it with a 800 watt Rockford fosgate


dual voice coil subs hook up mono on amp, from amp - from right side + from left side of amp run to sub n then jumper wires from one side of sub to the other side goes negative jumps on positive and positive jumps on negative

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.

Sub Wiring


Hello jtkpay,

Rockford-Fosgate claims their latest V-power 1500bd is stable to 1 ohm, and I would think that your Oldschool would also be. The 2 wiring options for 3 subs with 2 ohm dvc would give you a 1.34 ohm load and a 3 ohm load. The 1.34 ohm option would mean more watts to the subs, but the amp will run hotter. The diagrams look like this:

Using just 2 of the Kickers, you can wire 3 different ways, with final impedances of 0.5 ohms, 2 ohms, or 8 ohms. You do not want the 0.5 ohm load. It's bad for the amp. You don't want the 8 ohm load. It doesn't allow the amp to produce as much power. So that leaves only the 2 ohm, with coils in series and subs in parallel. It looks like this:

Hope this helps. If it does, please rate as "FixYa".

Is it enough to power to 12 volge=ahagen 12oowatss dual 4 ohms


your Volfenhag 12" subs are rated at 1200 watts they are only 600 watts rms and the Rockford punch p4004 is only 200 watts rms so the answer is yes it will work but if you get a amplifier that pushes out 500 - 600 watts rms you will love the sound from subs
there is nothing wrong with the Rockford amp it just wont pound out the bass as hard but the good news is you will never blow the subs with it
when buying amps or subs make sure to look at rms rating that is the true power they actually have ie. (sub box says 1200 watt you think powerful but if you divide it in 1/2 you actually get 600 watts rms) don't get me wrong that's a nice rating. for a sub but you will want to match that number with the amps rms rating or lower. The RMS is what makes the car pound the higher the RMS the better
hope this helps

I have a rockford fosgate p250.2 amp hooked up to two 12' subs but the amp is not powering on... instead the protect light is on and im not sure if its because its so cold outside... please help and thank...


Remove the load from the amplifier (subs) and the RCAs
Retry.
If the light stays on, there are internal problems with the amplifier, and it needs to be serviced.
If the amplifier works normally, attach the RCA's and power on again.
If it remains on, connect one sub, and then the other.
Your amplifier is a 2 channel amplifier rated at
60 Watt - 4 Ohm - 2 channel(s)
125 Watt - 2 Ohm - 2 channel(s)
250 Watt - 4 Ohm - 1 channel(s)
Your amplifier is not rated for a 2 ohm mono load.
If you have Single voicecoil subs wired in parallel, you have a 2 ohm mono load - your amplifier will eventually fail.

Quick question, amp problem


make sure you ground wires arent shared, meaning run each ground wire from each amp to its own grounding point

Sub hook ups


There's a lot more factors involved than that.
  • Power capability of the subs
  • Type/size of the sub box
  • Allotted space in the vehicle for the sub box
  • Voice coil impedance of the subs versus the capability of the amp
  • Etc.

Rockford Fosgate 800a2 To 2 SVC 2ohm subs


Ok.. Bridge the two sub into 4ohm than bridge to amp.


So. this how it goes.

sub1 + -
to      | |
sub2 - +
=      4ohm
       

           From Sub
                Two
            -          +  
            |           |
amp (L) - + (R)- +


This will use the full potiental of RF 800a2 amp. I believe it like 1153 watts max out.
