Question about Infinity Overture 2 Speaker

Bypassing the 150 watt blown amp with passive crossover

I have four Infinity Overture 2 speakers with blown amps (lightning strike). I think the crossover point is 350 Hz. Is it possible to build a passive crossover with all the correct parameters for the two woofers in each speaker and bypass the amp totally. Any advice on where and how to do this would be great.
Thanks Tom

3/4 update: i bypassed the 300w amp on my first ovtr3 with a cs3006 crossover i purchased on ebay. the input wires at the base of the speaker were connected to the input of the crossover, the bass output of the new crossover was connected to the yellow/yellow-black lf+/lf- wires that used to leave the old 300w amp. the high freq output of the new crossover was directly connected to the leads coming from the speaker's tweeter (running the midfreq outputs from the new crossover to the input of the speaker's old crossover is no good, since the midfreq output of the new crossover would rolloff and provide little high freq to the tweeter). The mid-freq output from the crossover was connected to the input of the old crossover that came with the speaker (alternatively, i could have wired the mid freq output from the new crossover directly to the midrange speakers, but i figured the old crossover might have had some characteristics that would have been helpful. the result is better than i hoped for! true, the bass is not quite as floor shaking as before (and you need an amp that can boost +5-+10db below 350Hz and rolloff the boost above 350Hz), but the end result is more than satisfying and gives these speakers new life. I am using a Sony receiver that puts out around 200W for the front speakers.

I'm purchasing 2 infinity 3-way passive crossovers on eBay with the same crossover freqs as my two overture 3's with blown amps. For 19.99 each, it's worth a try. Good luck to you!

My infinity overture 3 crossover does not work anymore (both sides of the crossover do not have any output. If I bypass it the speakers do work (obviously without the filtering) My question is how do I...


This is a 3-way speaker; specifically which speakers do you hear something from and which speakers do you hear nothing from? If the woofer amplifer is blown, for example, you will hear nothing from the woofers, but will hear sound from the midrange speakers and the tweeter.

Whats the wattage of the bulb used in peavey sp2 crossover, my sp2 peavey speaker bulb is blown


The lamp is an "1156" lamp... replace with that part number. Here :

http://search.digikey.com/scripts/DkSearch/dksus.dll?Cat=524517&k=lamp%201156

Or you can find it at auto parts store.

LIKELY the polyfuse device is ALSO gone... Probably similar to this one (1.1 amp, trip 2.2 amp):

http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=F2010-ND

or this one (1.85 amp, trip 3.7 amp):

How do i connect my pv2600amp to my peavey subs and top speakers, i have the leads but what do i do?


Line outs Left and Right from mixer to power amp Left and Right inputs,
Power amp outs to Subs(if they have passive crossovers built in check specs on subs).
From Subs then to Main spkrs. Make sure power amp is set in stereo mode using this way.

Alternative: You will need at least a 2-way stereo crossover unit inline after mixer and before power amps if the subs don't have a built in passive crossover. Most of them do have passive crossovers in the subs these days. Then separate amps or one channel would drive the subs and the other the main speakers. True stereo would require at least a 2 way crossover and two stereo power amps if hooking them up this way.

There is another option as is common with many sub setups. Send the signal to the mains using L/R outputs from mixer and a separate Mono output to the subs only. Putting only bass/kick and low frequency outputs in this send would help too.

Infinity 2 overture speakers- 1 wasn't working so I replaced the fuse. Now it works but doesn't have the same sound output as the other. Any suggestions?


Verify that the bass levels are set the same on each speaker. If they are and the problem occurs on all program material, you most likely have a bad driver or amplifier in the speaker. One other thing to verify is that the balance or output levels of the left and right main speaker outputs are set equally on the receiver.

Good Luck,

Need to find out how to connect acoustics 4050 amplifier bought a system at a swap meet with no directions also have infinity passive crossovers trying to install in 69 chevelle


http://mobile.bostonacoustics.com/Manuals/GT40Man.pdf
try this site to see if it's for your model, but if not it should still give you the basics for installation. Now for the crossovers, if they are passive they will go between your head unit and amps or speakers. if you can tell me the make and model of the crossovers, i can tell you exactly how to hook them up. Let me know if this helps :)

How do you set this stuff?


Need more info..
How many amps and their RMS rated power.?
If one amp, how many channels + individual power for each channel?.
Two crossovers set at the same freq.is redundant and likely to cause more problems.
Do the front speakers have their own X-over? whats the X-over point? and what is their freq. response (total) are they separates
Rear speakers same question.
I'll point out that you cant hear below 20Hz unless your a whale and very few instruments go that low except organs and synthasizers.
The subsonic filter merely block the lower harmonics from eating up amp power.
Their is no universal setting. all systems are different, as are cars, interiors, ears, windows up or down, noise floor, etc.
A RTA helps with the basics but you will still have to tune by ear,
Good sound is difficult enough to achieve,
Great sound is trial and error and very time consuming.
Sorry no simple answer here. Find a good installer ,preferably with sound judging experience,
It wont be cheap, but if you have enough money invested in the system, Don't skimp. or all you'll have is bragging rights
Best of luck, Sumthin

Car stereo crossovers


you should be able to remove the passive in-line crossover, but since it is blocking everything below 3500 hz, there is no need. leaving the passive crossover in place will also help protect the tweeters if something fails in your setup as any amped frequency below 3500 can seriously damage them.
