  • Which of these subs should sound better?

    I currently have an older Rockford Fosgate RFP2410 10" Woofer. I thought a newer sub would sound better so I got a Kicker C10 Comp 10". Well I installed it today and I think the older RF sounds better!! Should it? Could it be the box? Thoughts??

    I'm using an RF500X amp. I have it wired 4ohm bridged 250 Watts X 2.

    The box may meet different specifications than what you already have. Same thing goes for the amp.
    you may want to try out a different config wiring them up. The way you explained it is confusing, i.e. bridged and x2 are two seprate terms. Are either of them DVC or just single.

      By sounding good I mean... Just as loud or louder, hitting harder, tighter, etc.

        A good thing to ask now, is which C 10 did you get? The 2 or 4 ohm model?

        Also don't you just love the Kicker documentation. On their web site they state the C10 comes in 2 or 4 ohm models and thier manual for the same speaker says it comes in a 4 or 8 ohm model.

        Well which is it?

        On reason I dislike Kicker subs, especially the low end ones.

          The C10 requires a larger volume box, 1.0-2.4 cu. ft. where as the RF2410 only needs .75 cu.ft. What's the volume of your box?

            I have the 4 Ohm model. Not sure the volume of my box. It's just the elcheapo truck box like this one:


            Would this box be better for the new sub?

              thanks for clarifying your idea of sounding good, because for some of us we would have sent you in the completely wrong direction....seeing as sounding good has nothing to do with being loud and hitting hard...lol

              match the sub to the box and it will be a better option....compared to just going off of basic specs and shoving the subs off into a box that's not designed for them

                Quick STUPID question.. Am I sending TOO much power to this sub? Am I sending 500W RMS?? This is what the amp doc says:

                Maximum Power Rating
                All Channels - 1000 W
                Continuous Power Rating (RMS) - Measured at 14.4 Battery Volts
                4Ω Load Per Channel - 62.5 Watts x 4
                2Ω Load Per Channel - 125 Watts x 4
                4Ω Load Bridged - 250 Watts x 2

                And I have it hooked up like so:

                  looking at max power is like believing a used car salesman....

                  depending on how you have your sub set-up...I'd say you are underpowering it either way you look at it actually

                  14.4 volt ratings are a cheaters way of making an amp look more powerful than it actually is....i'd definately say you could use a more powerful amp....but it all depends on the sub that you have on it and the box as well

                    I understand that the 1000W MAXIMUM is crap but I'm talking RMS... How many RMS watts am I sending it the way I have it hooked up?

                    Thanks

                      I don't know, how do you have it installed?

                      that's a 4 channel amp and you're running it on only one sub?

                      is the sub a dual voice coil sub? what is the sub rated at as far as impedence? how do you have it wired up to the amp?

                      like I asked before....without that information you can't get very far

                      honnestly though, no matter how you have it hooked up, if your claim of 500w RMS is true, you're way underpowering that sub....IF what you say is fact

                        Why do you keep asking me how I have it wired?? I posted the diagram of how it's wired!

                        Yes, I'm only running the one sub on two of the channels (bridged) and I'm running my other 4 door speakers on the other two channels.

                        The tech from Kicker said I'm WAY OVERPOWERING the sub. He said I'm sending 500W RMS to a speaker wanting 150 W RMS. The sub is not a dual coil. It is rated 4 ohm.

                          4Ω Load Bridged - 250 Watts x 2

                          That means your sending 250 watts to the sub, 250 watts to the speakers.

                          And the sub is rated at 150 watts. Use the first sub in that case.

                          Edit: Btw you said your sending 500 watts to the sub. This is what I dont understand. If its wired the way the picture is it should be giving it 250 watts.

                            Yea, that is what the Kicker tech said. That's why I was asking to confirm how much I'm actually sending.

                              no he asked IF he was sending 500watts RMS...which is a no

                              sorry - I didn't throughly look at the document....it looked like two different wiring schemes while I quickly scrolled through it...something like you see an awful lot in owners manuals

                              250 x 2 it is

                              if you are basing your question off of the current sub then yes - you have enough power...

                              somewhere i got that the sub NEEDED 500 watts....now that I reread throught eh post again, I'm not quite sure where that came from....
