Brandon15zzz Posted January 27, 2013 Report Share Posted January 27, 2013 could it be that it can dissapate heat better? idk throwing things out here.

CJ18 Posted January 27, 2013 Author Report Share Posted January 27, 2013 The major differences that I see are the FL8.5k has less of the large copper coils, but more of the little silver topped things(dont know what they are, resistors maybe?) The 8.5k also has less of the big black cylinders, i think they are caps. This is the part that I would like explained. What each part is and what it does. I have tried looking around online and just get more confused. Just need an amplifiers for dummies 101 course. Link to comment Share on other sites More sharing options...
Guest Posted January 27, 2013 Report Share Posted January 27, 2013 you mean toroids and capacitors? Link to comment Share on other sites More sharing options...
knowledge Posted January 27, 2013 Report Share Posted January 27, 2013 here is a DDzse amp just for comparison REFF'SMy linkEBAYhttp://feedback.ebay...ck&myworld=trueI love car audio so much because I will never be done. I can never win, and I will never get it finished or perfect. It always has me coming back for more, I can never get my fill of it, but I get what I need.

CJ18 Posted January 27, 2013 Author Report Share Posted January 27, 2013 you mean torrids and capacitors? If you say so. I have no clue what they are. That is part of what i want to know. I am trying to read as much as I can, but words just dont cut it. I need a picture book! Link to comment Share on other sites More sharing options...
Wicks Posted January 27, 2013 Report Share Posted January 27, 2013 The major differences that I see are the FL8.5k has less of the large copper coils, but more of the little silver topped things(dont know what they are, resistors maybe?)

I have tried looking around online and just get more confused. Just need an amplifiers for dummies 101 course. The little silver topped things are the "12V" input caps for the power supply. They are directly connected to your battery/alternator(s). They filter the input current (ripple current) into the power supply of the amp. I can't tell the actual values, but a larger amount of PSU capacitance would mean it has to filter a large amount of input current. The large black cylinders are the voltage rail caps. They filter the rail voltage after the PSU has raised the voltage from ~12-14V up the rail voltage of the amp (Ex: 100VDC). Again, more capacitance means its filtering more output current. As Ray mentioned, with a much higher output voltage, a lesser output current is need, hence less capacitance...

Guest Posted January 27, 2013 Report Share Posted January 27, 2013 capacitors store energy and filter noise. toroids are transformers last I checked. like the ones that are on the power line poles Link to comment Share on other sites More sharing options...

One has more than the other, how does that effect the amplifiers output? Link to comment Share on other sites More sharing options...

Azagtoth502 Posted January 27, 2013 Report Share Posted January 27, 2013 Look up H-bridge tech to know about the SD & Stetsom amps. pa-pa-platypus sorry not everybody has a companies nuts so far down their throat they catch every drop ball sweat when it falls Link to comment Share on other sites More sharing options...
