Thread: Wiring for rear deck speaker replacement (with Monsoon)

This is a really old thread but uhhh... I'm going through the same crap. What did you you do?

I installed Infinity Reference all around and connected the only the low pass to the rear. I want to re-connect the 3", 2ohm speakers to the high pass and use the factory bracket. Does anyone know where I can get only these or aftermarket? Does anyone have two they want to sell?

I am also wanting to replace my 2004 6x9's. I will post my assumptions and hope someone with a correct technical answer will reply... I want to replace the factory 2-ways with Kicker 3-ways. Since the monsoon amp splits the signal, couldn't I just splice them together and connect it to the normal input leads on the new speakers? Also, does anyone know if the signal is split because the amp separates frequencies or is it is split to send more wattage to the woofer and less the the mid/tweeter? I would be suprised if the amp also acts as a crossover and splits the freq's..

I paid big $’s for the Monsoon upgrade in my ’06 Grand PrixGXP. It was a huge mistake! As I kept blowing speakers all around, I decided toupgrade all the speakers with aftermarket but it was a challenge to find 2 ohmand 3 ohm speakers that would fit. Finally, I did it! I’m a true audiophile andthe sound is HUGE.

The solution is simple. I used Infinity Reference all around;in the dash, the doors, and even in the rear deck. I bought two 9602ix 6”x9”,two 6502ix 6 ½”, three 3002cfx 3 1/2”, and two 075tx 3/4” tweeters. I shopped,bought online, and paid less than $375 for everything.

Everything fit and I kept all the factory harnesses intact.I simply clipped the leads from the crappy paper speakers and connected them directlyto the Infinity’s.

The only challenge was the rear deck but it turned out to befairly simple. I took my Dremel and cut the enclosure part off the X bracketthat held the 3” crappy mid woofers and mounted the Infinity 3002cfx directly tothe arms of the modified X bracket. I had plenty of clearance, since I didn’tmount the 6”x9”s to the plastic, snap-in, speaker bracket like the stock ones.Instead, I literally just dropped the 6”x9” speakers right into the cutout inthe back deck. Then I snapped the factory speaker bracket on top of thespeaker, making a super tight mount without any fasteners. I connected the lowpass to the 9602ix’s and the high pass to the 3002cfx’s.

Done! I know I lost a lot of the frequency response from allof the speakers because of the Monsoon amp/crossover but it was relativelyinexpensive and an easy installation. The sound I have is nearly competition. Ihope this helps everyone trying to do the same.

Also, If anyone wants to purchase the factory speakers Ipulled out, hit me up in a private message. I have them all except the 3” midwoofers that were blown.
