Default Aftermarket speakers replacing stock Monsoon system

I've got a few blown speakers in my '99 Firebird with the Monsoon system and am looking to replace them. I've looked at dealer prices for stock replacement speakers and its kind of expensive compared to aftermarket speakers. I've heard that aftermarket speakers aren't compatible with cars that come with the Monsoon system and you're better off finding stock replacements. Is this true or have I been wrongly informed and will be OK with aftermarket replacements

I was looking into getting these for the Mid-Bass in mine
http://cgi.ebay.com/_W0QQitemZ400016435825

And I believe this would work for the front doors, but not 100% sure on the tweeters... Also not sure if the woofer there is intended to be a sub/mid-bass or not.

The replacement packages I sell are actually specifically for your F-body. No guess work involved. I have 2 packages to choose from and they actually work with your Firebird. The Kickers that are listed there are not the correct subwoofer for sailpanels in a Firebird application and actually could potentially damage your stock amp, they will however work for a Camaro. I have the correct DVC subs in my standard package which is on sale right now for $277.00 shipped. This includes doors, sails and rear hatch replacements so every speaker in your car gets replaced.
The subs in Formula350's 93 Formula are completley different then what is in your 99 car unless he swapped in a Monsoon system. It is a common mistake though.

No, I didn't swap a Monsoon in, mine's the good ole pre-Monsoon 10 speaker HOWEVER I do plan to use a Monsoon amp from a 99 or 00. I have it and all the speakers except the mid-bass. The 4 door speakers are actually the Monsoon ones ATM. I have noticed a big change in ohms between them though. Like my rear Mids I think are the 4ohm and the Monsoons are 10ohm! I think that my amp does the crossover stuff (or whatever it's call) and the Monsoon doesn't. I vaguely remember removing or swapping some capacitors/resistors when I swapped in the fronts. The rest of my cars speakers now are still like-new, it was just the door speakers that were shot. Only reason I want some new mid-bass is for a bit cleaner and better sounding bass. The factory ones kick quite a bit of *** and if I'm listening to techno or the like, thump damn good, I attribute some of that to my deck though and it's frequency fine-tuning options.

That, and I'd never spend over $100 on speakers heh I got all the Monsoon's (minus mid-bass remember) and Amp for $50. Only audio piece I'd spend over $150 on would be a deck, but I have no plans to upgrade as mine does all I need.

You'll have to know whether the amp you got is from a Camaro or a Firebird because they are completely different and use different speakers - especially for the sail panel subs.

Sorry, completely wrong. 10-ohm speakers were only used in GM's base audio system with "extended range" (their term not mine) speakers. And the Monsoon amp does all the signal filtering except for the tweeters in a Firebird setup which have inline high-pass filters because they are powered by the head unit rather than the amp.

I suggest you read the Monsoon FAQ sticky for more information.

Thanks guys, and thanks for the offer Kee, but I think I'm just gonna order some Monsoon replacements from the dealership, they told me $50 per speaker and I only need 3 of them. I'll check out that Monsoon FAQ also.

Why did GM give the Camaro and Firebird different amps / speakers as far as ohms?

The Firebird is GM's "upscale" version of the pony car compared to the Camaro. The Firebird Monsoon system sounds a little better than the Camaro (not that either one is audiophile quality) partly because of the separate tweeters and extra bass power from the DVC subs. The Firebird version has dual voice coil 4-ohm sail panel subs that provide twice the power handling of an equivalent single voice coil speaker. To keep things relatively competitive, the Camaro version has single voice coil 2-ohm sail panel subs. In essence, this also doubles power handling over an equivalent SVC 4-ohm speaker but DVC speakers are somewhat more effective at using that power so the Firebird version seems to have better bass.

The Firebird amp uses four of its eight channels to power the DVC subs in both sail panels so all the tweeters are run directly from the head unit. There are only eight speaker elements in a Camaro so all of them run off the eight channel amp.
