Q: peter peter@greatnowhere.com wrote in does anyone know specs input voltage impedance etc on stock infinity amplifier in durango 99 im thinking about replacing the stock radio but will probably leave amplifier in place. the infinity amp accepts speaker-level inputs from the head unit and it puts out about 12 watts rms per channel at a somewhat reasonable distortion level take that with a grain of salt. its rated at 160 watts but thats peak power at something like 8% thd. the only good thing about the infinity amp is that its got pre-programmed equalization to make the infinity speakers sound good relative term. chances are pretty good that any decent aftermarket head unit will have more power than the infinity so it may be better to simply bypass the infinity and go directly from your new head to the speakers. of course your best bet is to replace both the head unit and the speakers. thanks! ive already replaced rear & front speakers with kenwood 17cm ones infinity speakers were blown but left stock tweeters in place. so youre using the oem wiring with the integrated crossover for the fronts also found pac swi-x adapter that will let me use control buttons on steering wheel! neat little unit. would you recommend tossing the amplifier and get a decently powered head unit or maybe get a head unit with no amp and re-use infinity amp can it be tricked into accepting line-out instead of speaker level inputs thx! peter considering youve already upgraded the speakers you might want to get a decent head unit and bypass the infinity amp altogether. this will give you more power to the speakers but youll have to run new wiring directly from your new head unit to the speakers. youll also have to get a crossover for the front tweeters as the oem crossovers are buried somewhere in the factory wiring. otoh you can always tap into the factory wiring after the infinity output which would enable you to use the factory crossovers for the tweeters. i doubt you can feed the infinity a line level signal as it was designed to accept speaker outputs from the oem radio. if you really want to stay with the infinity you can probably just run the speaker leads from the new head unit right into the infinity. theres no guarantee however that you wont overload the infinity input stage due to the aftermarket head units higher power. .

tom lawrence wrote yep - the computer knows how much fuel should be used on each injection event lets see... i opened the injector for 3 milliseconds with fuel rail pressure at 15000psi - that used x amount of fuel... subtract that... carry the one... okay next event... so it keeps track of that and sees how much fuel was used to travel a particular distance. from that it makes an mpg calculation. thats why when with a diesel you add a pressure box to increase rail pressure the fuel economy calculations get all out of whack. the computer thinks it injected x amount of fuel becuase it did a 3ms injection event at 15000psi rail pressure. but the rail pressure was really at 17500psi so it really injected about 1.2x fuel... the computer thinks it used 17% less fuel than it actually did. so instead of your actual 17mpg that youre getting the computers reporting 19.8mpg. all numbers are used as examples only and may not have any real meaning - so put down the calculators where does all this common rail pressure come from surely not from the punie little lift pump. i would have thought that the actuation of the injector would create the much higher pressure. i have come to this conclusion because of the location of the lift pump being between the tank and filter. that would make the filter an extremely high pressure can with a low pressure gasket on it. -- bill p. just dog & me .
