I've pretty much decided that i'm gonna go with a pair of rockford p3 sd ten's for my dodge quad cab. How powerful of an amp do i need. Each sub puts out about 180 rms, 300 watt peak. So would i need around 400 watt rms ? What else should i look for. The amp will only run the two subs. Also what is the difference between two ohm versus 4 ohm in subs ? Thanks[align=left] [/align]

 

Yeah you should probably have a 400 Watt rms amp, you dont neccesarily have to have that much but your subs wont be at there full potential w/o that much. Most car speakers are 4 ohm. If your amp is 2 ohm stable thats when you could wire 2-4ohm speakers in parallel (benefit of this is most amps will push more power in a 2 ohm config then a 4 ohm). I have never heard that either 4 ohmor 2ohm speakers soundbetter than the other. I would always experiment whenI hooked subs up either running them parallel or series,on a single channelor indivdual. Maybe some1 on here knows the "perfect" way to hook them up indifferent configurations. Ialways tinkered with it untilI thought it sounded good.

 

I have a pair of rockford p3 10's w/ a rockford 400w amp in my '04, mine are bridged to get the most power out of the amp. It bumbps pretty good in cab (turns my stock seats into massagers) but its not real obnoxious outside the cab. Noting rattles like most of the little rice burners do. Thats my $0.02 on the matter.

 

I am waiting for delivery on the MTX thunderform matched with a kcker amp. I will let you know how that goes. MTX wired the two subs to be at 2 ohm. The Kicker is stable at 2ohm, so we will see how it goes. That install is next week's project!

 

RF p3's I think are dual voice coil subs. depending on how old urs are. newer ones I think are DVC. this changes how your wiring would be. two dvc subs thar are 4 ohm subs wired in parallel would be 1 ohm. if they are SVC then it's just 2 ohms. no difference in sound it's just the resistance of the sub. they olny have to do with wiring options. how many + and - plugs are there on each sub. if there is one of each ten its a SVC if it's two of each its a DVC.
