Question about Rockford Fosgate Punch P550.2 150W x 2 Car Amplifier Car Audio Amplifier

1 Answer

Power fluctuations I have this Amp hooked up to 2 12's type r subwoofers. they hit pretty hard and then sometimes they hit really hard. I mean they sound fantastic. But its only for a couple of minuites and then it goes back to just a decent amount of bass that Im used to. I cannot replicate these situations regardless of remote settings, lights on lights off...etc..etc. If you need more information I can find it out. Me and my friend put this installation together and its just driving me insane! thankyou in advance! -jj

    Ok I left out information untill i looked at it thoroughly. I completly checked every fuse, rewired it to this diagram which matches with the subs that I have ( bottom). The only problem I found was the Fuse between the battery and the amp had minor corrosion.The alternator was running a little over 14 volts, the battery at 13. The 100Amp fuse was a little over 13 volts and so was the terminal of the 4 guage wire from the battery to the amp. The temperature is not a problem because its inside my truck compartment and while im driving listening to it the tempatures never exceed 80 degrees, also the amp runs very cool ive never fealt it to be to hot to the touch. I also checked the ground to be completly sure that's not a issue compacting the bigger problem. Im gueesing tghe next best thing is a capacitor. Meh.... mabey this helps J.J.

This is due to a few things, Your amp, the tempurature in the car, the size gauge of wire, and the alternator, When your hittin hard bass and you notice over time it kinda dies out, it means that your sub is losing power cause of the lack of power your battery and alternator produce, If the amp is fairly big then it needs alot of power to keep it at peak performance, I would recommend getting an capacitor that is well suited for your amp, this will give you the constant power you need and the bass will always stay bumpin hard for a significant amount of time, Also the tempurature greatly affects the performance of amps cause the hotter it gets the less power it delivers then possible shut off where then it will cool off for a brief moment then return for only a litle while if still bumping

Car amplifier just shut off and goes on and off when it wants


Driving the amplifier too hard causes it to go into protect mode to prevent damage. The amp periodically recovers and operates normally until the next overdrive peak hits it.

If i have a 4 channel 2000 watt amp, can i use 1600 watt wires if i only have 2 subs hooked up to it?


Yes, you will be fine. 4 gauge power wire is sufficient for a couple of reasons, the primary one being that most of the companies that are boasting 2000 watts for a 4 channel amp are off brand "web-retail only" companies, and they severely over rate the power output of their amplifiers. Secondly the supposed 2000 watts is peak power and not rms power. Peak power means how much power that amp can put out during absolue climax of the music or during a tone burst. RMS power is how much that amp will put out continously to your speakers or in this case, your subs. If you look at the spec sheet of that amp, in all actuallity you're probably only getting 200-300 watts rms even bridged.

On a side note, if you really want to push your subs hard, you might want to consider getting a mono block or "class d" amplifier and use that 4 channel amp to push your surround speakers. Class d/mono block amps are specifically designed to push subwoofers and will give you the most efficient power out and the best heat dissipation to withstand the output required to drive subwoofers. You'll get better bass and also more adjustability to tweak the sound levels coming out of your subs. Hope that helps.

Hooking sub up


Hello missywarden,

According to the specifications, the amp is capable of "tri-mode" operation, that is, running normal speakers on the individual channels while also powering a subwoofer in bridged mode.

Your sub needs to be a minimum of 4ohms and should be relatively efficient. I'd look for a sub that has an RMS power range of from about 75 watts up to a maximum of 250 watts.

The sub connects to the leftmost speaker terminal (positive - right channel) and the rightmost speaker terminal (negative - left channel).

It's not going to be a really loud subwoofer. The power is 360 watts RMS which will be shared by the normal speakers and subwoofer.

Hope this helps.

Amp cutting out when bass hits


With an amp like that you can not pull enough power from you cars battery alone. That is why when it hits hard it drains the amps from your battery and you amplifier cuts out. The light on the amplifier most likely dims when the bass hits. You need to get a capacitor. They are easy to hook up on the main power wire. You can get one from http://phatcaraudio.com/capacitors.html or get a used one off ebay.com. Good luck

Subwoofer wont play


Check your rca cables they might be loose or not connected to the amp or the radio. Sometimes those rca cable outlets get worn out by being bumped, moved, hooking up and pulling out connectors. Plug in your rca cords and wiggle them on the amp while radio is on and see if the music cuts in and out

Improper function


try hooking up your subwoofers in series. then connecting them bridged to the amplifier. as follows: positive from sub#1 into positive of amplifier left channel.. negative sub#1 into positive sub#2. negative sub#2 into negative amplifier right channel. turn the gain down as this will sound pretty loud.
