i was wandering, right now i have my rears hooked up to a seperate channel. so far im impessed, but i was told, hooking them up in series would give me a better sound,
but this has brought up a few questions.
1) my speakers, kicker K65's, have an impeadance of 4ohm, and a RMS rating of 65w. if going into series, will i beable to achieve 2ohm safely? my amp is 2ohm stable, and will run at 100w in 2ohm
2) will i still have stereo sound?
if all thats possible;
3) are there wiring diagrams i can follow, or would looking at sub wiring for SVC models suffice?
any help would be most appreciated, thankyou :-)

As long as your amp is 2 ohm stable you shouldn't have a problem.  Just bridge the rear channel.
Do it right the first time

to bridge my amps channels, do i take the positive wire from my (example) Left channel, run it to my left speaker, and run a positive wire from that speaker to my right speaker, and then a negative wire from the right speaker to the right channel negative on my amp?
or am i missing something?
i was finding diagrams on rockfords site but they are for subwoofers, and i dont think it explained it properly for a speaker setup.
any help would be appreciated

i found this image on the Basic Car Audio Electronics' site'
re-wiring my rears -- posted image.
this is what i should follow to have my 2 speakers run @ 2ohm and in stereo as well, correct?

Say what...... if these are rear speakers and not subs then do not wire them in series and do not bridge the amp to mono. Stereo means two speakers and two channels. Who on earth told you to wire your rear speakers in series?

/r7, have you been hanging out at one of those goofy forums?
Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

@stevdart: nope, and thats why i brought this here to ask people i have a little more faith in for wiring anything together.
this guy that listened to my setup said the bass sounded flat, i told him its probably my lp setting & the frequency i've set it to, however he insisted on series'ing it up to run more watts @ a lower ohm... he said thats how he did it on another persons setup for his subs & rears. though im sure his rears would be mono if he did it up like he said.
This guy runs a computer business, and figures he knows it all, hence my apprehention and curiosity into his theory.
on a side note about my flat sounding bass:
i cant figure out howto find 40hz without any tools to help me. if i were to find or create a 40hz sound and repeat it on my deck, could i adjust my frequency till i can hear the sound?
im in no rush to fix it just yet, it may be more urgent when i actually recieve the fronts i've been waiting for, for over a month,
Thanks for the help guys, appreciate it.

Use one of the above, make yourself a test-tone CD.  Very useful for setting crossover frequencies, and setting gain with the use of a DMM.

The guy who "advised" you is talking strange language.  For one, series wiring doubles the ohm impedance, it doesn't halve it.  Two, any speakers wired in either series or parallel must be on the same side of the stereo-either left or right-to maintain a stereo signal. 

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

A lot of times what may work for someone will not work for you. I should have answered the question a little more direct. If you chose to wire the speakers like you suggested, it would in fact be a mono signal. Thus do not do it and at the same time a series wiring setup would knock the available power down by 50%.

Post the model # and make of the subs and amp that runs them as well as the type of box the subs are in. We can then look at that part of the system to see what can be done.

atm i have no subs, just my 5 channel amp, which is SoundStream Tarantula 800/5, my rear speakers are Kicker K65, no box ;p, but will be changing their box enclosures for a stronger mdf box for each speaker, this will allow me to get rid of some of the raddle and noise the plastic stock box enclosures are causing, and hopefully remove some un-needed noise.
hth :-)
