Camaro time bomb

My wife’s Camaro just went into self-destruct mode. It seems like all at once, everything broke. The thing is 8 years old but it has low miles, and we take good care of it. The windshield cracked, the brakes warped, the differential’s making noise, the speakers blew, and the battery gave up the ghost.
The most challenging repair was the speakers. She has the premium Monsoon sound system, and it has some crazy components. The front 6½” speakers have separate inputs for the woofer and tweeter, with the crossover in the head unit. My first thought was to simply frankenstein together some aftermarket speakers by bypassing the crossover in the speaker, but I was horribly wrong. It turns out that they used 2Ω woofers and 4Ω tweeters! Most aftermarket speakers have 4Ω voice coils, which would mean crappy bass response. I looked up the price of the factory replacement speakers, and they were $90 EACH!
A quick internet search found that many people had suffered this situation and found a solution with Infinity’s Kappa speakers, which have 2Ω voice coils. I picked up a pair of 60.9cs component speakers, and wired ‘em up. The main dilemma came when I read a little on impedence matching. It turns out that most amps can easily drive speakers with higher impedence than rated, but using a lower impedence speaker can damage your amp. I was worried that the 2Ω tweeters would cause problems. The increased power would also mean overwhelming highs. You could solve this by going to your local RadioShack and wiring a couple 1Ω – 10 watt resistors in series with the tweeter, but I chose to just hook up the included crossover to the tweeter and use the -6dB button to reduce the output (RadioShack was out of the resistors I needed).
The Kappas sound awesome, and they’re loud enough to drown out the horrible noise coming from the rear end! Let’s just hope nothing else breaks!
This is how you install the 62.9i
Afer going nuts and reading up on the stuff on this board, I attempted the install of the Infinity 62.9is in my 2002 Camaro Z28.
1. Just take a wire cutter and cut the off crossover box at the end, and let it fall into the trash can. Now once you strip away at the end you'll see 3 wires, a RED, WHITE, and BLACK. The red one is the positive wire for the Midrange speaker, the white one is the positive wire for the Tweeter speaker, and the black one is the common negative wire for both speakers. (Connect BOTH negatives to this one).
2. You must soder the wires (soo easy) to the red/black wires that were connected to the stock speaker. Make sure you connect them to the right wires or it will not sound the best and you can do damage. (You know which wires are the right ones by looking at the Monsoon wiring diagram in the sticky).
3. It's easier to connect and soder the wires on your kitchen table instead of knealing next to your car door, so make sure you unscrew the larger "plastic ring" around your door speaker, so you can just unclip the wiring harness and bring the whole piece inside.
And there that's it. 62.9i instead of 62.7i problem SOLVED. :woot2:
**The only thing is I think these speakers are not worth the price and o yeah, one of them is f****n BLOWN right out of the box but there's nothing I can do about it because I can't return them because I modified them. WTF!!!! :eeek: (by the way this is my seccond crappy experience with sonic electronix they SUCK).
My advise is that if you really want better sound, don't waste your time and money and just go with a fresh aftermarket system.
