View Full Version : Amp/Speaker Question...
OK, I've popped one of my rear speakers. I can't stand the farting sound, so it's time for a descision.
I'd appreciate technical info if you can give it (electronics engineer here).
I can buy aftermarket 6x9's and put those in, BUT, the stock speakers are 2 ohms with dual (HighFreq/LowFreq) inputs, what a pain in the backside it'll be to find some like that!
In your expert opinion, which would be the best solution for me?
Buy aftermarket 6x9's and only connect the low frequency channel?
Buy aftermarket 6x9's and connect the low frequency and high frequency channels together?
Buy aftermarket 6x9's and and aftermarket tweeters - connect the low frequency outputs to the 6x9's and install/connect new tweeters to the hi-frequency outputs?
Disassemble and modify the Monsoon amp in the trunk to bypass the crossovers (whereby I can use normal 4 ohm 6x9's) ?
Buy an aftermarket amp and use it in place of the Monsoon amp in the trunk (whereby I can use normal 4 ohm 6x9's) ?
If anyone has any information or experience changing out the Monsoon amp for an aftermarket one, I'd be grateful for that!

Sorry for not helping, but I have a follow up question that might help us both:
Is each speaker each 6x9 (woofer and tweeter) 2 ohms each, and wired in series for a total load of 4 ohms? I'm not sure how x-overs work :(
I currently just have my 6x9's hooked up to the low channel, I can't really tell if it is running at half power or not.
terisk: How does it sound wired to the low channel only?
A crossover is usually a passive LC filter with a stop band for low frequencies and a pass band for high frequencies (high pass filter) -and/or- a stop band for high frequencies and a pass band for low frequencies (low pass filter).
6x9's usually have one bi-directional electrolytic capacitor connected in series with the tweeter, providing a simple high pass filter (stops the low frequencies from damaging the tweeter).

I would forget the 6x9's, and install a set of 6" diameter component speakers, connecting the low-input to the 6" speaker, and the high input to the component (tweeter).
Fabricating an adapter to fit a 6" round speaker in a 6x9 hole is easy.

What do you mean by "component speakers" ?
They have separate high frequency and low frequency inputs?

component speakers are your best bet when it comes to music clarity. the midrange/woofer are totally seperate from the tweeter. with the 2 being seperate it allows for better imaging. they are usually expensive compared to a good set of components. and for what you would spend on buying a set of components, taking the time of building a plate to mount them, and the headache of messing with factory wiring you could buy a good set of aftermarket speakers and an amp and sound really just as good. unless you do your homework and set the components up to have the right imaging i dont think you would notice that much of a difference between components on the factory amp and 6x9s on a aftermarket amp.
Gotcha.
Can you get 6x9 component speakers? They all seem to be round ones. I'll losing a lot of diaphragm putting in a 6" round driver as opposed to a 6x9, so I'll lose bottom end...
I definitely don't want to be putting subs in the trunk, etc... I just want a decent sound, not something that sounds better than your average home stereo!

Oy, so many people w/ this same problem. Here goes;.. The rear 6x9's are indeed dual input. There's a line coming from the head unit for the tweeters & a line coming from the amp for the woofers. The woofers are 2 ohm, the tweeters are 4 ohm. DO NOT connect the two (wire the two input wires together.) or you'll screw everything up. Aftermarket speakers are 4 ohm, Monsoon are 2 ohm. If you connect an aftermarket to the Monsoon you'll only draw half the power from the Monsoon amp & will sound like absolute crap in comparison to the Monsoon 6x9. For a comparison connect one aftermarket & leave a Monsoon 6x9 hooked up. The Monsoon 6x9 will drown out the aftermarket so much to the point where you'll question whether or not the aftermarket is working.
If you want aftermarket speakers you need to get an aftermarket 4 channel amp. (The Monsoon amp is designed to run the 2 ohm load w/out it it's a weakling)
You're Monsoon 6x9 is more than liekly not blown, cut the cloth to see if the tweeter post is broken off it's mount that's the cause of the rattleing 99% of the time.
Hope that all helps, alot of people are puzzled about the Monsoon it is not conventional, that's for sure!:)

But could you insted of buying a 4 channel amp, just hook up an aftermarket head unit, and run all 4 speakers off that, and bypass the Monsoon amp all together??

Ya, you can, but you're not going to get anywhere near the potential that the speakers can produce, and you're most likely going to end up blowing the new aftermarkets off just the headunit cause it's not putting out enough power for you...

I have an Alpine 9847 head unit, Alpine Type S 6.25" components, Polk Audio db 6x9's, a Pioneer Amp powering a 12" Alpine Type E sub. Can all of that go into my car though, without using the stock Monsoon Amp? and if I have to use an aftermarket 4 channel amp, what is a good one going to run me??

your speakers will be fine off the headunit, but they would sound better with an amp. a 4 channel would be good all around, but a 2 channel would really be all you needed for the components.
alpine, jl, kicker, fosgate, crossfire, etc. just pick a brand :lol:

Hehehe this is exactly why I DIDNT want a monsoon system, what a PITA!

i wouldn't have cared. the only thing that's still factory in emily's car is the harness that plugs into the radio. if it would have been very much trouble i would have just bypassed it. there's only 3 wires that makes a radio work. then you've got a couple more for fancy stuff, like dimmers.
