Car Stereo and Electronics / incorrect stock door speaker
« on: May 04 2014, 01:30:26 AM »
After listening to the stock CSII system belt out crackly garbage for the last 10 years (time flies I guess) I finally buckled down and decided to change the stock speakers.  Actually, I figured I'd replace them while I replaced my outer dew sweeps with the repros I ordered like 3 years ago...

anyhow, the stock 5.25" speakers I had in the door were p/n 16054454: A 4 Ohm speaker found in other late 80s-early 90s Buicks.  With the 10 Ohm 3.5" dash speakers wired in parallel (stock configuration), the deck was subjected to only a 2.85 Ohm load.  Bad.  I ended up keeping the stock deck, stock 5.25s and just replacing the in-dash 3.5" speakers with more modern 4 Ohm ones.  I rewired the fronts in series so the deck would only have to deal with an 8 Ohm load.  Overall, it sounds much better now.  Not amazing, but definitely acceptable.

The door panels had never been off.   I searched for the p/n on turbobuick.com and it seems it happened to at least 1 other member there.   I wonder if they just ran out of 10 Ohms on the assembly line and put in what was on hand.

General Buick Tech / ATR pitbull muffler question
« on: March 05 2012, 01:55:09 PM »
Finally posting after registering almost a year ago.  Finally transitioning from tbs.com.

Did ATR manufacture application-specific mufflers ? 

I have the 4 stainless mufflers from my old impala SS quad muffler system.  The ones on my Turbo Regal are the aluminized steel ones and have seen better days.  If the mufflers weren't specifically designed to cancel out a specific frequency I was considering using the 2 centre ones.  They seem to be roughly the same dimensions as the Turbo regal ones.
