Which is better?

2 12'Sony Xplod Subwoofers 1200watts,350 watts continuous rms

2 12'Rockford Fosgate Punch P2 subwoofers 50-250watts rms (500 watts peak)

And can the fosgates be powered by a sony xplod 1000 watt amp 2 ch?

[jakegday]

the rockfords, without a doubt

you wouldnt buy car audio equipment at a department store would you?

Okay, how many RMS total will I be able to get using my 1000 watt amp??

example 2 fosgates P1S410 Power Handling:
Peak: 300 watts
RMS: 150 watts
Impedance: 4 ohms

Or can my amp power more then that?



And thanks again.

sony amps will give you about half of what you think they will.. for 2 seconds

basic rule of thumb, if its in walmart it should not be in your car. end of story

I just need to know how many RMS my amp can handle. I really don't understand on how matching your amp and subs work. But If you guys can give me somekind of info on it then I will know what I can work with. I am planning on getting Rockfords but not sure on the watts and rms. This is what I want to get:

10" Single 4 ohms Punch Stage 4 Subwoofer

alright....its not about how many watts rms ur amp can "handle" its about how many watts it can put out. RMS is the continuous wattage amps put out at a certain amperage i.e. 12v, 14v......but a car only puts out 12v. as long as your sub can handle as many watts rms as your amp can put out, then you should be fine. its probably better to get a sub that can handle a little more than your amp is capable of.
now you say you have a 1000 watt amp. is that max power? what voltage is that measurement taken? there is no magic "formula" to calulate anything like that. all that information should be included with your amp/sub. and if they arent, do some research and find out. these are things you need to know in order to see what your amp is truly capable of and thus, which subwoofer is the best match with it. hope this clears some stuff up.

Heres what I found:

Audio System
Max Output Power / Channel Qty:
380 Watts x 2
Crossover:
Active crossover
Additional Features:
Input level controls
Response Bandwidth:
5 - 80000 Hz
Signal-To-Noise Ratio:
93 dBA
Continuous Power / Channel Qty:
165 Watts x 2
Amplifier Output:
2-channel
High Level Inputs:
Yes
Input Signal Voltage:
0.3 - 6V, 1.2 - 12V
Crossover Slope:
18 dB/octave
Low Pass Frequencies:
80 Hz
Output Power / Total:
1000 Watt
Distortion Factor:
0.008%
Amplifier Output Details:
165 Watt - 4 Ohm - 20 - 20000 Hz - THD 0.04% - 14.4V DC - 2 channel(s) ¦ 200 Watt - 2 Ohm - 20 - 20000 Hz - THD 0.1% - 14.4V DC - 2 channel(s) ¦ 400 Watt - 4 Ohm - 20 - 20000 Hz - THD 0.1% - 14.4V DC - 1 channel(s)



With this said, does this mean I can get two Rockford subs that are 150 RMS and 300 watts? Or should I get something higher? I don't mean to sound dumb, I just don't have no one else to ask.

those are the only 2 things that really matter in all that. so its a "1000" watt 2 channel amp, but really it only puts out 330 watts at 14.4 volts, which a car is incapable of putting out constantly. all of the outputs listed are at 14.4 volts, so they are almost useless. u need to find the power output at 12 volts. now that is a pretty weak amp, it probably wont put out enough power to get the sound u want. if you are set on that particular amp, i would bridge the two channels together and get a 10" or 12" sub that can handle more power. like i said before, its always better for the sub to be able to handle more than the amp can put out, that way the chances of you blowing it are reduced.

the amp and subs you mentioned would do alright, but 165 watts (it will be less at 12v) to each sub is not alot, but you may not want it to shake apart your car like i would want it to do. its all about how loud u want to go. the more power the better (in most cases), but with that power comes capacitor(s) and all that jazz. its better to ask questions now before you do it, than to do it and figure out you did it wrong.

Thanks millrtime for your help. I really appreciate it.

[lilsweets3138]

Another question, whats the diffrence between a 10" RF and 12" RF?

[jakegday]

about 2 inches

[Schister66]

Just my .02....spend the extra money and get a set of either Infinity or CDT. Rockfords arent very good and Sony XPlods are straight up garbage.

i second that, amps and speakers, i know this from experience, im not just some random shit talking asshole, there 1000 things that you just shouldnt buy at a department store, car audio is one of those things
