Are my watts matched up properly?

Question

I have two Rockford P3s dual 4 ohm (500 rms 1000max)hooked up to a p1000 stable at 1 ohm (1300rms 3950max(birthsheet)) so its 650rms watts for each speaker. ive heard fosgate subs are underrated like thier amps are so i can overpower them a little (im not absolutely sure thats true though). but anyways it matches up good on the rms but in terms of max its 2000 for each speaker which is twice as powerful. should i only worry about the rms or consider the max as well. i just dont want to damage my speakers.

Answer 1

The max wattage is where its peak when they blow them in testing, all the do if force watts into the subs in testing and when it blows they put down the number of watts right before they die. RMS or "rated" is what you want to look at. If you want to push a full 500w rms to both subs then it will cost you a pretty penny, but luckily you can get amp of lower wattage and it will work just fine. Now you said the amp is only stable at 1ohm? Your gonna want an amp that is the same ohm rating as the subs. Also it depends on how your subs are wired, if you have them in a box where they share the SAME terminal than it you be best to look into a mono amp or good dual channel (BRIDGEABLE) amp. Whether or not they share a terminal, THIS amp ( http://www.caraudiodeals.com/power-acous... )will be perfect for you, if your subs are separate, then it will push 450watts RMS at 4ohm and if you have them bridged then it pushes 1048 which is barely over the bridged RMS of your subs...plus its cheap. PA makes good stuff, Ive been using their amps/subs/and caps for years and they all work fine. Also don't forget the capacitor for your system. Check into a 2-3 farad cap. Also please check this Audio calculator to be sure your battery and alternator can handle the draw. http://www.datafilehost.com/download.php... if you draw a full 1000w you may need to upgrade to a deep cycle battery and high output alternator.

PA amps work perfectly. Mid range quality? no. Im sure you've never used them and are going off of other peoples words and not your own. In most cases my customers choose PA over memphis, mtx, hifonics, and others that I offer, because they are inexpensive and work great. No one has had any remarks other than praise for their setups. (after 34 installs with PA amps and only 2 people complained, the amps died after a month...but that happens to all products, you get the majority that work and the few that don't so its not even calculable)

Answer 2

Do Not purchase Power Acoustik!!! They are overrated, do not provide what they offer, and give mid-level performance and sound quality! I'm sure You already knew that tho. :)

And they way you have it wired, plus the equipment you are using is great! If you ever feel it is too much for the subs, simply turn the amp down.

But stick to what your on. It is better to have Enough power.. than Not have enough and be craving for a little more. Running a bigger amp at half is better than running a smaller amp at 100%.

Nice set-up!

Answer 3

its all about the rms is you double your rms you s going to blow the sub no matter how far you turn down the amp. its way to much power to the subs. best bet is to buy a amp that matchs the total rms of your subs and they will last a whole lot longer.

Answer 4

The RMS number is the one you need to be worried with, and if you're overpowering each sub by 150 watts at 1 ohm and you play these regularly, not just in competitions then don't be surprised if they burn up fairly soon.

RF doesn't have a great track record over the past 8 years or so. And now that they are sold in bulk through companies like Crutchfield, all they worry about is production numbers...not craftsmanship. So any hearsay you've gotten about them being able to handle more than rated is potentially true about any sub manufacturer out there. Most subs can handle more wattage in low doses but a steady inflow of wattage beyond the manufacturer's recommended range is taking an unnecessary risk.

Answer 5

You really don't need to worry about the max. It's really a bogus number. It doesn't happen often enough to make it a problem. from the looks of it, you've done your homework. The amp and the subs are a really good match.
