ok lets say you have a 50X4 receiver.. is it possible to series your RF and your RR speakers and series your LF and your LR so that you will get more power to them? instead of 50... getting 100.. if you know what im talking about reply

I wouldnt do this. I think when you attempt to bridge the headunit, it lowers the impedance and will blow the internal amplifier.
Someone correct me if im wrong.

it will lower it when you parallel....

Well...even if it were possible, it would either lower it to 2 ohms (if its a 4 ohm channel) or raise it to 8 ohms which would totally negate the increase in power.
You are better off buying an external amp.

dude.. when you series something .. it will double. when you parallel it will cut your ohms in half. so please someone who knows about electricity please post.

Yea...but in car stereo, there's something called ohms. And in a series circuit, ohms double. In a parallel circuit, ohms cut in half. But w/e, i guess 3 electronics classes in an auto school mean i dont have any electronics experience.

and if i series it, it should use the power comming from the RF and combine the power from the RR. IF YOU SERIES

so if you had 50X4 it will now be a 100X2

do you know what i mean now? i think you understood me wrong in the first post or something.. i dont know. sorry

The minimum Ohm load on any aftermarket head unit is 4 Ohms.

If you series your speakers you will double the ohms, which cuts the power in half.

Tedd is right. Just leave it be or buy amps.

If you series it you will actually loose overall power. If you TRY and parallel it you will just blow fuses if not the radio.

Sorry, Im sure this isnt what you wanted to hear

Thank you ryan. Now i know my 3 electronics courses and my 4 years of car audio experience hasnt gone to waste :thumbsup

let him find out himself... also that cd player doesnt put out 50RMSx4.. it probably does around 13 - 25 or so.. anyway, since you want to argue with everyone... give it a try :words

no. you cannot bridge a head unit.

short reason: no negative voltage rail in a head unit amplifier to support bridged mode with an inverted channel waveform.

P=I^2(R)

When resistence is raised, power is lowered. Hence: P/R=I^2

P= Power (watts)
I= Inductance (Amperage)
R= Resistence (ohms)

ahh...dc formulas. you're bringing back memories of last semester's DC eletricity class....good times.

Hey rehabb, sorry if i came across as an @<hidden>$$ last nite. Its just that it seemed like you came across real hard and strong and insulted me. Sorry we started on bad terms. Hope u accept my apology and i hope you stick around the board.

Happy posting :cheers:
