How do I hook up one sub to my rockford fosgate p3001 amp


Hey i have looked over many rockford manuals,(i own a 300.1 my buddy owns a 325.1) and for there mono(.1) amps there hooked together on the inside so channel A+ and B + are cencted on the inside the amp. So you ither hook one 2ohm sub to channel A or you can hook 1 4ohm subs to channel A and 1 4ohm sub to channel B. There 2ohm stable so any lower will eventualy burn the amp out.

Wireing diagrams


Hello stingerman20,

Your Directed D2400 amp is CEA2006 Compliant. It is stable at 1ohm and will produce 1,200 watts into that load. So you want your subs wired as close to 1 ohm as possible.

The only 3500 watt Pioneer Premier series subs I could find were the models number TS-W3002D2 and TS-W3002D4 with dual 2ohm and dual 4ohm voice coils respectively. The wiring options for the D2's result in 0.5ohm (too low), 2 ohms, and 8ohms. Your best option would be the 2ohm configuration which would be voice coils in series and subs in parallel. Options for the D4's result in a 1ohm load and a 4ohm load. Your best option would be the 1ohm configuration which would be voice coils and subs parallel.

To see the wiring options, try Rockford-Fosgate's "wiring wizard".
Select 2 woofers and the appropriate voice coil impedance and quantity and click "search". It'll bring up all of the possible wiring configurations along with the final impedance load.

Hope this helps.

Need amp for 2 15 l7 4 0hm


Hello jasonjohnson,

There would be more amp choices if those L7's had the 2ohm voice coils, allowing you to series the coils and then run the subs parallel to the amp for a 2ohm load. As it is, you'll probably have to run them as either 1ohm and have limited amp choices, or as 4ohm and settle for a little less power.

An absolutely excellent amp to use at 4ohm would be the Alpine MRP-M1000. At Crutchfield this one is on sale for $347. For more power, and an amp stable to 1ohm, I would recommend the Rockford-Fosgate Punch 1000-1bd, a "factory refurbished" model is available at Crutchfield for $349.99. It's $700 new.

Both of these amps have adequate power for 2 L7's, but the RF will definitely be the better power choice. Both are also well respected names in mobile audio and the prices are reasonable.

If you have deeper pockets and want to push the subs really hard, a Rockford-Fosgate Punch 1500-1bd will put a full 750 watts RMS to each sub.

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".

Using JBL 4410 3-Way crossover, trying to use PG 12" Dual 4-ohm


ok, connect the amp positive to the positive end of one sub coil, take the negative of that coil, and run it to the positive of the second sub coil, then run the negative out of the second sub coil to the negative of the amp.

Amp problem, need help!!!


Sounds like one of two problems: either your subs are beginning or have gone bad, or you amp is going bad. What size power and ground wire are you using? You should be using at least a 4 gauge for both. Also what impedence are you running with the amp, ie; 4ohm mono, 2ohms stereo, etc?

Amp connection


Parallel would be the best way to wire them. 2 4 ohms subs to one channel wired parallel would be a 2 ohm load for that channel and if u wire them series then 2 4ohm subs to one channel would be an 8 ohm load for that channel.

Wiring


The T10001 can drive a load lower than 4 ohms. Wire the coils of the individual speakers in series to make each speaker 8 ohms. Then wire all 3 speakers in parallel and connect them to the amp. This will give you a 2.6 ohm load.

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.
