Any ideas how many watts I can smash into a 4pill 2879 fatboy base amp without killing the pills?

Well normally a 4 pill needs around 100 watts bird drive. which is 2 2sc2290's. that is what I use to drive mine in my mobile the base should be the same. the main think is the voltage the 4 pill is at. some people use 2 2879's to drive a 4 pill but I think it is useless. Hope this helps.

I drove it with a rm 203 yesterday and saw somewhere around 940 pep. Need to measure bird today both the rm and the fatboy.

Ok well I don't know to muchabout the rm203 never ran one. All I know about them are they have mosfets in them. I have ran some rm amps in the past but never one that small so not sure of the wattage it will do. Now I forgot in my first post to say I do not read my wattage with a peak kit. I only use RMS but I do have a bird with a peak kit and I hooked it up for you. Hear is my results: My Fatboy 2 pill with 2 2sc2290's in it was swinging 100 bird RMS not sure on peak forgot to look, but the 2 pill driving the 4 pill was giving me 500 to 510 bird RMS and around 1200 peak. I was running it on a regulated power supply in house the power supply is regulated at 15vdc. I hope this helps. Oh ya I about forgot I was using a Cobra 29ltd radio from Dustin at RRCOM the radio will also depend on your output but it should be close as long as you can get a driver to do around 100 bird RMS

u put 100 bird into a 4 pill amp and you should blow up in a matter of seconds. No more than 50-60 watt bird into a 4 pill 2879 amp at 14 to 15 volts. And thats with the radio doing no more than 4 watts dead key . you will no when you swing back if your over driving it .

Hey Highvoltage what you talking about I put 100watts bird swing into my 4 pill everyday. LOL I run a fatboy 2 pill with a 123built 4 pill. LOL I run my truck at 18volts all the time. I run the 2 pill on 14volts and 4 pill on volt line. That is what 123 told me to put into it. LOL I use a 2 pill to drive my 4 pill and my 6pill. humm well even when I am on the keydown line I use the same 100bird drive into my 4 pill at 20 volts. now I am not talking about Deadkeying 100 bird into the 4 I said 100 watts bird drive Rms swing. but I guess differant strokes for differant folks, but I have been running the same amps for alone time and never blow them up. lol. charger and 123 have been good friends of mine for the whole time I have been keying and I have ran my stuff the same for years.
some people run 50 bird into them that would be a 1 pill. but hey look they also build 2x4 amps as well heck fatboy has a 2x4 with all 2879's in it.

u stated 100 watt bird drive. im talking dead key watts. in a 5 pill configuration . the 2290 or a 1446 is tuned in the circuit to drive the 4 pill section to receive around 20 - 50 bird dead watts. with 2 2290's your drive would be around 20- 70 bird watts. its rated to be a 60 watt pill . its wrapped with 4 to 6 turns of wire so it produces less watts , say around a 40 watt dead key with one 2290. don't get fooled about how much you should drive it with or how much you can drive it with until u overdrive it and sound like caca . lol lol
Yes I understand that I know how an amp works I have built them myselft before. I was talking about swing not deadkey. So I will clear it up real easy I use a 2 pill with 2sc2290's in it. That is what 123 told me to use when I had him to build my 4 pill. I really don't know how people read watts but I read watts with no pep kit. I should of just been more clear and said I key 20 bird and swing 100watts bird. but to answer the question of the post A 1 pill or a 2 pill should work fine. That is what charger recommends when you buy them.

foooooooooooooooooo 10 roger . cool
Hey hv I am not trying to be a smart butt or anything but I just figured by saying 100watts bird drive you would know i didn't mean dead key but I just know what I have used for years maybe I am driving my stuff to hard but I havn't had any problems. I really don't know Idid do a test earlier today using a 1 pill fatboy that I had laying around it was swinging around 80 bird and it still did as good as the 100 bird out of the 2 pill with 2290's. I lost about 30 bird on output. the 1 pill amp has a 2879 in it. Hummmmm I don't know. I just didn't want you to think my last post was being a smart butt. I just didn't want to fuss about it if you know what I mean
