Ok, so i have never really been into the stereo stuff before so i'm looking for some advice. I decided i wanted to add some bass to my car and i am working with very limited space. I have all my air ride stuff, 2 7 gallon tanks, 3 compressors, all my valves, and my nitrous bottle in the trunk. So i decided to just do a single 10" sub. I went to the stereo shop and after listening to several different subs, i decided to get a Rocford Fosgate P2 10" sub. Now i have to decided on a amp to go with the sub. This is where i need some help, i know nothing about amps, so any input would be much appreciated.
well you NEED to know the coil configuration of the sub. I am willing to bet that P2 is a single 4 ohm coil. Find a nice mono amp that puts out 200-300 watts RMS at 4 ohms and be done with it man. Brands to look into would be Rockford, Alpine, Soundstream, Cadence, just to name a few that are going to have good bang for the buck.

i vote for alpine. m-500
4 ohm power=300 its perfect
click sig for my car audio videos
Cadence TXA-3002 would feed it 600w RMS at 4ohms and runs about $130. Serious bang for your buck...
TXA-6004 is awesome as well... 600x2 at 4ohms for $180 but you have no use for that.
Thanks for the help guys, you guys answer quick as hell lol. If it helps any here are the exact specs for the sub,

What are you willing to spend on the amp? You can buy a nice budget minded amp, or a super high end amp, it all depends on your budget man.

If i have to i would spend up to $350 on a amp, i'm wanting to get the amp and sub combination lined out so i can move on to doing the rest of the speakers in the car to make it sound really clean, i'm going for quality, i would like to hear the words clearly, but also have some bump to go with it.
Well, i want decent quality out of the sub, i'm wanting to spend more money on the deck and rest of the speakers, i'm not into the really loud bass, but i do want something that if i want to turn it up, it's gonna be heard. Thanks for the help JL. It's gonna be another month or 2 before i get to the deck or fronts, i am getting the car painted at the end of this month(hopefully if my paint guy comes thru), so there gonna have to wait just a little bit longer. I just wanna finish the sub and amp combo so i don't have to worry about it also. I am leaning toward that Rockford 400 watt that you posted, it would be nice to have everything as a matching brand. You've been a great help, thanks a lot bro!
no problem for the help... Matching amps is always nice, and if your amp matches your sub so be it, but when it comes down to your front speakers, I highly advise against RF, simply because anything of high quality they offer for speakers, can be outdone cheaper by other companies.

If space is an issue and you wanna eventually do the speakers you could look into a 5 channel. Or a 4 channel and bridge the last two channels for sub. But I dont really have any specific suggestions.
I have never put a amp on componet speakers, hadn't even thought about it really. I'm new to the stereo stuff, but can i run them off the deck like normal and have them still sound good with the sub, or is a amp a must for them?
You can run them off the head but theyll be power starved and will sound 100x better on a good amp. But I havent ever had a set. Thats just what I hear around here.
Look at it this way... if you have a set of speakers rated to take 100w rms and feed them 18-20w rms(which is what 99% of head units can provide), they are going to sound fine up to a fairly conservative volume, but then you start sending a clipped signal when you turn it up. You are trying to send more and more power to get more volume because the speakers can't really open up, so by trying to push more volume without having more power, the power gets distorted and will trash your speakers. By amping them with closer to or higher than their rated power handling, you give them good clean power sooner and don't have to crank that volume knob so high to get more volume, because your amp is giving the speakers easily what they need...
Basically, it is ok to run aftermarket speakers off the head unit if you are easy with the volume and understand how to treat them, but with them amped you are getting their full potential easier, and better.

Thanks, that's exactly what i needed to know. Guess i'll be looking for a amp to power them when i get to that point.
