Rockford P3001 Its say 1x300 with 2ohms hows whould I be able to run it like that it looks like in the manual that I have to wire the first and 2nd speaker wires unlike most amp when you run the first and last spots?

Is this right?

I wireing a daul voice coil 4 Ohm sub with this amp and don't want to wreck anything off the bat? I'm going to run the daul voice coild in parral to get the 2 ohms to the amp.

 

Yes....it's a mono amp with 2 sets of speaker terminals that are paralleled inside the amp....wire your voice coils in parallel and use 1 + and 1 - on the amp.....

thank you very much for the fast reply thats what I thought I just wanted to make sure !!

 

You're welcome....have fun with the new toy.....

 

another ? for you I hooked it up right and turn up the filter thing to about 60 hz is that about right?

also when I had the gain turn way down on the new amp it cuts out but if I turn the gain about 50% it seems fine does that sound right to you?

 

Without knowing what else you have running in your vehicle it's hard to say....generally in a system with an after-market deck, amp and speakers I usually start tuning with the low-pass filter set around 80hz.....


When you say way down I assume you mean at the lowest voltage number on the dial....if you are using an RCA level signal from your deck find the number that matches the RCA output voltage listed in the deck's manual and set it there.....it sounds to me like you need to find someone who knows how your equipment is setup and get them to set that gain control for you....last thing you want is to damage the amp by having it set incorrectly.....

Just to clarify things a little. You're going to wire your voice coils in parallel to create a 2 ohm load for your amp. Then you simply have to use one set of terminals on the amp to connect the subwoofer.

Having 2 pairs of speaker terminals on a mono amp is a design feature intended to make hooking up two woofers a little easier. You only need to use one pair. (+) from the amp to both (+) on the voice coils, and same for the (-).

80Hz is a good place to set your Low Pass Filter.

As for your gain (input sensitivity), if that **** is turned all the way counter-clockwise, you've turned the sensitivity down on the amp. If its too low, the incoming signal from your head-unit isn't being processed properly. If you set your input sensitivity too high, then you induce a bunch of extra noise that the amp makes while amplifying that incoming signal. Distortion could result, things'll just sound bad.

Look on page 4. Set the switch to LP. The frequency dial should be set right in the middle between 60-125Hz. And I'd set your gain to the 5 position.
Also, just use the terminals labeled for speaker 'A'.

I would also set the "Punch EQ" to minimum.

What make and model is your head-unit?

 

ok thanks for all your help I'm going to turn the gain down abit each time I go for a drive till I find a good spot for it but it does sound good all the way up.

I Have a cheap Sony head Unit.

I Have the filter set at about 80 Hz should I turn that up abit?

 

OK I have the same amp, mine is set at 80hz so that should be perfect. As for the gain I have had mine for 4 years and it has never cut out on me no matter where the gain is set at. What I have always done and most others as well is -
1) get a CD you know well
2) turn all boost, loudness, etc on the deck off, also all bass, mid and treble controls to zero, & turn the gain on the amp right down (counterclockwise)
3) disconnect all other speakers except your subs
4) turn the volume up to the max you will listen to it at
5) start to slowly turn the gain up until you start to hear distortion then turn it back down a little
6) hook the rest of your speakers back up and see how it sounds
7) if you have too much bass and can't hear the front speakers clearly you will need to turn the gain down until everything is the same volume level
BTW is this the only amp you are running? Or do you have any others?

Its the only amp I have I think it sounded like it was cutting out on me because either one of the RCS cable was realy lose, or I think this was the broble I Had the Filter all the way down when it was doing it and the song I was playing had no bass playing at the time it sounded like it was cutting out.

I think it is working good now though.

Thanks for all your help !!!

I Have just stock speaker don't have the money to spend on good stuff.

I just wanted the sub and amp to give me more bass.

Thanks again all you guys have been really helpfull !!
