Im looking at this rockford fosgate p700-1bd amp brand new for $300 it comes with a birth sheet it says 750 rms on a 1ohm load. i cant find any reviews about it 225 rms x 1 @ 4-Ohms 450 rms x 1 @ 2-Ohms...


You can't go wrong with Rockford, in my opinion. Everything they make is well built and high quality. I personally have two Rockford p500-1bd amps hooked up to four 12 inch subs in my car and those amps make those subs slam. I have them wired down to 1 ohm and the specs say that they should be pushing 500 rms a piece at 1 ohm so that p700-1bd amp really packs a punch. Depending on what you're hooking up to that amp I would defenitely recommend it to you. - Ryan in Alaska

Which amp goes with 2 jl audio w3v3 4 ohm


Choosing a amp isn't always easy but it first begins with what you want.

--RMS of the speakers is what you want to use to find your amp.
That's going to tell you what watt's your speakers can REALLY handle @ 4 ohms.
--Also what you want to spend $$$ will determine how clear it sounds.
--I prefer a Rockford Fosgate amp for base and kenwood for highs.
--Also look at the RMS watt's rating to find the proper power and go a bit beyond what you want so that the amp performs with ease.
--Last but not least you chose the amp for how many speakers you are going to connect to that amp. For example if you are using 2 JL audio 12" for subs, then a mono amp is perfect. But if you are connecting 4 speakers, you should begin to find the amp with four channels so that you obtain left, right , front and rear sound.

I installed a sony 600watt amp and it works but old rockford fosgate 200 hit harder how do i make my amp louder and evenly spread throughout my car


Hello jmanbutt99,

The old Rockford-Fosgate was probably producing the rated power. The Sony is most likely overrated. But, it's supposed to be stable on each individual channel down to 2 ohms and will deliver 65 watts RMS into that load. So to get the most from it, your best bet would be a pair of 4 ohm speakers paralleled to each channel. A relatively efficient speaker like the Kicker 07DS600's shown here should provide pretty good sound.

http://www.crutchfield.com/p_20607DS60/Kicker-07DS600.html?tp=105

These will work with as little as 6 watts RMS and can handle up to 50 watts RMS so the Sony should power them really well. They're 4 ohm so a pair in parallel will present a 2 ohm load.

Hope this helps

Here are a few amps at Crutchfield.com you can look at. Notice that the closer to a class D you get, the price more than doubles. I have 2 Kenwood 12's that are 800W Rms, and I have a cheap SPL 1500W amp pushing them. 148.5 Db in a 93 Eclipse, so don't worry too much about the class unless you have money to burn. Let me know if this helps :)

Is it enough to power to 12 volge=ahagen 12oowatss dual 4 ohms


your Volfenhag 12" subs are rated at 1200 watts they are only 600 watts rms and the Rockford punch p4004 is only 200 watts rms so the answer is yes it will work but if you get a amplifier that pushes out 500 - 600 watts rms you will love the sound from subs
there is nothing wrong with the Rockford amp it just wont pound out the bass as hard but the good news is you will never blow the subs with it
when buying amps or subs make sure to look at rms rating that is the true power they actually have ie. (sub box says 1200 watt you think powerful but if you divide it in 1/2 you actually get 600 watts rms) don't get me wrong that's a nice rating. for a sub but you will want to match that number with the amps rms rating or lower. The RMS is what makes the car pound the higher the RMS the better
hope this helps

Rockford Punch HE2 wiring question.


if your sub will handle it, bridging it will give you more power. The best thing to do is to find out how much power the amp puts out ( RMS ) and if it is in your power handling range bridge it. It sounds better and gives you a harder punch because of more power.

Rockford fosgate punch 700s gets very hot


Disconnect the speaker wires from speaker terminals on the amp and turn the amp on (turn the head unit on). Set the volume to zero on the head unit.

Does the amp get hot?

If it does, either the bias is set to high or the amp has other problems. If it does not, you may have the speakers wired to the wrong ohm load.
