6 Speaker Stereo Question

[Adam423]

Hi,I have a 2003 Vibe with the 6 speaker stereo, 4 speakers and 2 tweeters in the upper door (no sub) with the amp under the passenger seat. I read all the great info in the other posts (thank you!) and have a few additional questions if anyone can help.1: Is the under seat audio amp a 4 or six channel amp? Does anyone know the wattage of each channel or point me to some official specs? Here is a great pic that someone else posted FYI: http://forums.genvibe.com/zero...o.gif2: I plan on keeping the stock amp with a new HU and I am installing new component speakers in the front with separate passive crossovers, woofer and tweeters. I don't know if I should use the crossover supplied with the new speakers and hook up direct to the just the woofer output on the amp and then the tweeter to the crossover. Or use the factory amp crossover/amp and bypass the new component speaker crossover.My preference is to use the component speaker crossover but if the factory amp/crossover has an internal crossover for the front speakers then the new speakers will not get any HF. The tweeters do have a cap attached to them which leads me to believe that factory crossover is external but then the drawing shows separate outputs.Also I noticed that the front door speaker was labeled 2 Ohms, which is kind of strange for a factory amp, 4 Ohms is standard. Maybe the woofer and tweeter are being driven by a single amp and the total load of the factory woofer, tweeter and crossover is 4 Ohms?Anyway, does anybody have any direct experience with this issue.ThanksAdam

I want to say its a 4 channel amplifier with the tweeters running off of the front door speaker signal, no idea on the wattage but its nothing too impressive, they are 2 ohm speakers after all. go ahead and install the new speakers with the crossovers they came with and if you notice a lack of power or any unusual issues, remove them. for the sake of knowledge i would vote to replace the stock amp, especially with aftermarket component speakers, if nothing else for more power.to reference the drawing, though it shows separate outputs, it also shows the dashed line over them, which could indicate the crossover. i could be completely wrong here, but its a thought.thats correct that the speakers are 2 ohms, in some attempt to create a better sounding stock system the 2 ohm speakers would be better than the 4 ohm at delivering mids/lows, while the tweeters would cover the lost highs.Ive replaced my head unit and installed a line output converter, but i have not yet replaced my stock speakers, when i do i will definitely be buying an aftermarket amplifier though.also, i noticed this was your first post, welcome to genvibe!

I read all the great info in the other posts (thank you!) and have a few additional questions if anyone can help.IF you have tweeters, you have a 6.5" in each front door, a 5.25" in each rear door (IIRC, they may be 6.5"s too, not 100%) and the tweeters in the front door sail panels... 6 speakers total 1: Is the under seat audio amp a 4 or six channel amp?

I don't know if I should use the crossover supplied with the new speakers and hook up direct to the just the woofer output on the amp and then the tweeter to the crossover. Or use the factory amp crossover/amp and bypass the new component speaker crossover.to utilize the factory amp with an aftermarket HU, you'll need a LOC (Line Output Converter) You MUST use the supplied crossover with components, it's designed for it.. the factory amp doesn't have any sort of crossover on it, the factory 6.5/5.25"s run full range... The factory tweeter has a cap on it to block the lows.. IF you us an aftermarket HU, a lot of them come with crossovers built in anymore.. This can be used to help remove some of the lows from the 6.5/5.25"s to help protect them.. using a High Pass crossover, set really low (50hz) can remove everything from 50hz and down, to protect the mids.. (they can't produce it well anyway)My preference is to use the component speaker crossover but if the factory amp/crossover has an internal crossover for the front speakers then the new speakers will not get any HF. The tweeters do have a cap attached to them which leads me to believe that factory crossover is external but then the drawing shows separate outputs.see aboveAlso I noticed that the front door speaker was labeled 2 Ohms, which is kind of strange for a factory amp, 4 Ohms is standard. Maybe the woofer and tweeter are being driven by a single amp and the total load of the factory woofer, tweeter and crossover is 4 Ohms?Not that strange, a lot of factory systems run like this, gets more, out of a smaller package, but it also means that if you run anything 4ohm YOU WILL GET HALF THE POWER...!!! Anyway, does anybody have any direct experience with this issue.ThanksAdam See above, welcome to GenVibe..
