Togo Posted October 6, 2006 Share Posted October 6, 2006 what makes a $100 capacitor better than a $20 capacitor besides the name on the pacakge (as i know now even rockford stuff is made overseas!) what is the difference between 1.0 Farad, 1.5 Farad, and 2.0 Farad what exactly does a capacitor do? what will it gain me? will it have negative, positive, or neutral effect on the charging system / battery? (no pun intended) anything else i should know. reason i ask is that i have a gift card at Frys electronics and they hae a 1.5 Farad Cap (with blue neon light) for $19.99 Link to comment Share on other sites More sharing options...

Togo Posted October 6, 2006 Author Share Posted October 6, 2006 found this online..http://www.satcure-focus.com/tutor/page6.htm that's kinda odd - so it turns D/C into A/C - so on to the other questions - one brand better than the other? $100 vs. $20? since there is no real electronics in a CAP - and my best guess is that most if not all of the CAPS are made in china, is there any reason that my system will suffer/ gain with a $20 CAP?

ChadC Posted October 6, 2006 Share Posted October 6, 2006 the new caps for cars have higher quality conpontents (sp) and do not explode when shorted out (ooze yes, but go boom no).the audio caps need to be polar. many pc board parts are non polar. ( I might have that backwards?)100w to 1000w = 1 Ph2000w to 2500w =1.5 ph2500w and up = 3ph and more.do you want to put $400+ of stereo amps at risk by using a $20 part?you do not need a digital display.. they are for teh gay.no effect for the charging system. It will benfit the battery. Link to comment Share on other sites More sharing options...
Loud Pedal Posted October 7, 2006 Share Posted October 7, 2006 A capacitor stores electrical energy. It is sort of like a battery in that sense. What it does for an amp is provide it an electrical buffer so the amp can draw quick surges of electricity for pounding subs while avoiding power dips.I have a source for wholesale audio equipment. They don't carry everything, but they do monster cable, phoenix gold, sony, and others. Let me know if you or anyone on the forum wants me to price anything.David Link to comment Share on other sites More sharing options...
Guest Steve Mulvey Posted October 7, 2006 Share Posted October 7, 2006 Go to Fry's and buy a capacitor there. They are prety inexpensive and as someone has pointed out , they are kind of like a battery. In an auto application, you are using the capacitor to reduce or eliminate ignition noise. Noise is caused by voltage spikes on the 12 dc line into the radio and the cap absorbs them. Don't waste $100 on a cap, it should be about $2-. I believe if you ask for a noise suppressor for a radio (they have a component section for ham radios and stereos) , you will get what you need...Steve Link to comment Share on other sites More sharing options...

It is a quick release (and recharge) of voltage when the amplifiers need it.cheerschad Link to comment Share on other sites More sharing options...
