Rockford P3001 wiring help

[lowryder99]

Im just curious if anyone can help me here, Ive asked the question briefly before but was still a little confused.

http://www.fullsizechevy.com/forums/showthread.php?t=137907&highlight=P3001

My amp is a mono amp 150x1 at 4ohm's, 300x1 at 2ohm's.

Now my question is, There are two sets of speaker inputs on the amp, how can I maintain a 2ohm load if there are two sets of inputs? Do I need 2 ohm subs wired to each channel to see that 300x1?

Right now I have two single voice coil 4 ohm sub's wired to the amp, basically i have them wired individually to each channel on the amp. So exalted said the leads are connected internally, does this mean the amp automatically kicks it down to a two ohm load? Or am I just running 75 watts per sub?

This leads to my final question, how can I wire these two 4 ohm subs to get to the 2ohm final load to get the full 300 watts? If I wire the subs together ill just have 2 wires to wire to the amp and that still leaves me with an extra channel not being used on the amp?

Sorry if this makes no sense, if it doesn't just let me know and ill try to explain better,
Thanks!

The speaker outputs are internally bridged. Having 2 sets of terminals just makes installation easier if running multiple subs. To get the most of your amp, you will need the final load to be 2 ohms, whether it be (2) 4 ohm SVC’s or (2) 2 ohm DVC’s like the following diagrams:

Exalted was right … the amp is internally bridged, so your amp is seeing 2 ohms, thus 300w … 150w per sub.

See above.

Hey Nemy.................can you reinforce what you are saying a little more? ;)

LOL, thanks a ton dude. So my plan right now is to run two 2ohm dual voice coil subs, but the above diagram leaves me with two wires to go to the amp, a positive and negative. What about the other terminal on the amp?

If I am to wire two dual ohm sub's to each channel how would I do it to keep a two ohm load? Im just sorta confused still because you said right now the amp is bridging down my two 10inch (4 ohm single voice coil subs) So wouldn't it take both dual 2 ohm voice coil subs and bring it two 1 ohm?

Just leave the other terminal unused or hook each sub up to its own terminal, it doesn't matter.

Because you are wiring each sub in series first then parallel you would still end up with a 2 ohm load.

Read THIS (http://www.jlaudio.com/tutorials/dvc/dvcAdvantage.html) paying attention to what series and parallel wiring do to the final ohm load. You can also look through the rest of their TUTORIALS (http://www.jlaudio.com/tutorials/index.html) they are pretty good explaining how things work.

Thanks, that JL link doesn't work however, asks me for a password.

I guess what im confused on is I didn't know i could leave one terminal not connected, and if I used the above diagram's from rockford's site id only have one terminal connected.

And then when exalted told me that by placing my two 4 ohm's subs on EACH terminal on the amp it bridged it down for me, now if I ran two dual 2ohm subs to each terminal it would do the same thing would it not? (internally bridge it down) If not, why would it bridge down my two single 4ohm subs, but not two 2ohm dual voice coil subs..

I mean I can see on that dual 2 ohm diagram where i can just not join the two wires on each subs to make it one wire, but im still confused as to why wiring both of those 2ohm subs into each terminal won't kick it down to 1 ohm...

For the JL site just got to jlaudio.com and choose tutorials, about the middle is The dvc faq, read the advantage of a dvc.

The amp is a one channel amp, the manufacturers put 2 connections on the amp for ease of hooking up multiple speakers. It does not matter whether you wire the subs together and then hook to one set of connections or wire each sub to its own connection.

As far as the subs are concerned, the reason it will still be a 2ohm final load, is beacause when you follow the diagram above, the 2 voice coils of the subs are wired in series (- of the first coil to the + of the second coil) which makes the sub a 4ohm load, just like your 4ohm single voice coil subs. When you wire to of these subs two your amp you end up with a 2ohm load.
