Can anyone tell me how many watts a Rockford Fosgate Punch 120a amp puts out? There is no sticker on the bottom of the amp to tell me anymore. Plus, I cannot find anything online. Does anyone happen to know how many watts it puts out? And, tell me if the wattage output is good, fair or poor? Any help would be greatly appreciated!
Do you mean the "120.2"? Because it's 30 watts per channel at 4 Ohms, or 60 @ 2 Ohms.

Just made the order for around $150 through CarDomain. I currently have a pretty old Kenwood amp that I'm hoping to replace with this to my JL 12w0 sub. How is this Rockford amp?

Yes, it is safe to bridge your amp, provided that you realize that it increase the chances of the amp overheating, because it is making twice the power.

I am running 2 JL audio 10W7's off of a RF Punch 401s amp. The amp is 2 ohm stable and I have the subs wired in parallel for a 1.5 ohm load. The subs are 3 ohms each so if I run them in a series it becomes a 6 ohm load which I dont want. Is this half-ohm likely to cause any trouble? The majority of amps out there are only stable up to 2 ohms which will likely limit my selection when I upgade in a few months or so. The entire system is wired with 4 gauge wire and supported by a 1 farad cap so I am positive the amp is recieving good voltage. Any thoughts?
yes it is to low for the amplifier it will play but it will get hot and when the volume is loud the speaker protection on the amplifier will kick in by cutting your output to half for a few seconds or the amplifier will go on protection after a couple of minutes
Well, you need to look more closely at the ratings on the rockford 2400. It really doesnt do 2400 watts. That is just a rating they use to attract buyers. The RMS ratings is what counts here. Most likely it isnt more than 800w total. If you can look at the RMS specs, it wil give you a better reference to how good it will pus these subs. My guess is that I will Work, but Not power them efficiently!
