Ok so here is what i got going on

I have a buddie thats going to help me wire my truck up hense i dont know how to and he is going to teach...

I also know nothing about sound systems so here is the question I pose!

Ive got a Jenson 500 watt amp(bridgeabe)
And i want to put a thin sub in I was thinking Rockford Fosgate P3

My first question is should I go 10" or 12"

10" is 300 RMS and 600 Peak
12" is 400 RMS and 800 Peak

Me second question is 2-ohm x 2 or 4-ohm x 2
to be honest I have somewhat knowlage but am not totally sure of myself I belive that the 2 ohm vs 4 ohm has to do with your head unit but im not going to have it powering the sub only the amp will be....and rms vs peak im thinking is rms is what it takes even when its not hitting to run and peak is full force watts it takes when its fully hitting which leads me to think that 10" is the rout i wana go but let me know

3rd and final question befor I dig into this.... On the driver side door i have a little black box with 2 cables that resemble the cables that you put from the dvd player to a tv (I KNOW IM A NEWB LOL) but if i understand correctly that little box enables me to use the factory head unit and run a amp??? anyone know whats up there???? ( I know the guy befor me had subs but i never got to see that all hooked up or anything) I was under the impression you could only use a amp with a After Market radio but I dont know alot soooooooo

ALL YOU GUYS THAT WORK ON THIS AUDIO STUFF HELP ME OUT HERE PLEASE!

 

The ohms has nothing to do with your HU. It has do with the resistance your amp is working with (resistance= work), so the harder it has to work the less output and warmer it'll run. So I'd say go with the 2ohm, but with the P3s you need a 2-Channel amp to do cause they are DVCs. Not too sure about bridgeable amps but you need to know the RMS of the amp, this should at least be in the upper 1/3 of the RMS of your sub(s). Best is it to be higher so you don't clip the signal and blow your subs. I'm not new to this but others know tons more than me. Low e Red, mSaLL150, hen23.

I'm going with JL 12W1- 300RMS 600Peak and putting a Pioneer amp- 400RMS 800Peak

 

Thanks Texas Tech i do have a 2 way amp btw

OK SO THERE IS MY AMP SPECS SO WHAT DOES THIS MEAN FOR THE SUB THAT I WAS GOING TO RUN UP ABOVE?? Please explain it as if i was a retart because i really dont understand this crap lol
