  1. Rockford T1000-1bd $500 Phoenix Gold sx2 1200.1 $549 dc audio 1.2k $349 what are the major differences assuming they all do rated power at 1ohm
  2. I have a mixer and a mic few in to a CB radio.. it sounds good and clean. How even for efficency I would add some additional frequency filtering... First for audio amp efficency I would like to cut everything below 80hz and above 3khz (it's questionable if any CB actually broadcast and thing below 100hz ot above 2khz... But... Second I would like to be able to run some studio monitors without feedback I have adjustable talk back built in to radio but any amount of talk back sets off feedback... ($40 combined)Mic shure pg57, Mixer Behringer Xenyx 502 i am looking for options for relitively inexpensive gear ($50-$75) to complete this task... I know it's a super low budget and understand the quality of gear I am bound to end up with... feedback filtering isn't required and neither is an equalizer but a parametric notch filter low/high filter is...
  3. Would there be a better location to seek out this information?
  4. I buy my mosfets from digikey or ebay i dont generally need 1000 mosfets so i buy them from ebay. good rule of thumb if te mosfet blew so did the resistor following it... If the resistor blew and the mosfet looks good it probably isn't.. If i have an amp apart and i am replacing the mosfets i do all of them for that particular section of the amp (if the mosfets blow on just a single channel i replace all of them for both channles) there cheap enough like 100 resistors is usually like $2.50 and 50 mosfets is usually less ten $30
  5. Disclaimer: So i purchased this amp used with instant protect mode for $20 at a pawnshop. so if i repair the output finals and they blow again im not out any large amount of money... The amp is rated at i think 260 watts per channel @ 2 or 520 bridged at 2 which is higher output then the 340 watt kenwood i am currently running.. Upon inspection of the board and removal of the blown mosfets x3 (the middle one didnt blow nearly as spectacular as the ends but its fried as are the resistors) I noticed the board is printed and drilled for a 4 mosfet final what advantage would it have to solder in the 4 th mosfet and associated components and if the existing output resistors are 100 1/4 watt 5% what would i replace both output chanles with? if i went form 6 mosfet final to an 8 mosfet final or would keeping it at the 100 resistors with the 4 mosfet final be fine? There wired in series? If i need 300 ohm per channel should i replace them with with 75 ohm if i go 4 mosfet final? http://i286.photobucket.com/albums/ll114/jgilk1/Mobile%20Uploads/IMG_20150602_215624.jpg
