Hi all! I recently bought an 88 Bonneville SSE from a buddy (Black ext/grey int) and i have a few questions about it.
I did find alot of what i was looking for by searching, but from what i could see pretty much nothing is the same between years and models (LE, SE, SSE) and info on the 88 SSE in specific wasn't the easiest to find.
Stereo. I replaced the headunit with a normal ISO unit and changed the 6x9 3-way rear speakers, the 5 1/4 2 way fronts and kept the stock tweeters in the dashboard.
According to what i've read here the dash shouldn't have any speakers/tweeters at all there, only the speaker grilles, with the Performance Sound System. Aftermarket?
I managed to find the color codes for the stock wires here and rebuilt the stock wiring to match ISO standard for easier replacement later, but i seem to be having some sound issues though.
I read that the rear speakers should have an amp somewhere. Where is it and how powerful is it? The should be a button/switch to turn it on as well, but i can't find any switches that makes the sound better or different in any way.
Was this only with the BOSE system and not with PSS?
Regarding the sound issue: With all speakers playing at once, the sound is horrible. No bass and choppy mid and high range. If i fade it to the rear and one side (One speaker playing) it sounds good though. Is this the stock amp just sucking at running my speakers? I haven't replaced or run any new wires, all wiring from headunit to speakers is stock.
I'm assuming this has something to do with weak amps for the speakers, but i've run similar setups directly from a CD-player before without any issues like this at all so i suspect the factory amp, if there is one, is too weak for the job, or just gets the wrong kind of signals from the headunit. Suggestions?
Are the antenna plugs different between the different years/PSS/BOSE/Models or can i use any convertion plug. With four weeks delievery time i don't really feel like ordering the wrong one. Not even once.
There is also a wide range of warning lights on while i drive. Well, atleast the Brake and ABS light is. The Brake light is because of the parking brake switch. I can deal with it being lit as long as i know why tbh. ABS concerns me a bit though since these cars seem to lack and ordinary master cylinder and booster. If the ABS pump goes, so does my brakes?
During the winter i've noticed that the ABS works, at times, dispite this light. A couple of times the pedal has been rock hard as well, but that has been after heavy acceleration (No vacuum) like an ordinary brake system would without vacuum to the booster.
Is the master pump gone/going or is it just another case of "Learn to live with it"?
I might also add that classic cars is my passion and way of life, ABS is not really vital. I've never had a car with it before and i'm not that desperate to get it now.
Removing the bulb for that light sprung to mind, but if it'* something serious i might as well keep it there and actually fix the problem and not remove the reminder.
I also have a water leak from the sunroof. It looks like the entire mechanism on the passenger side is rusted to pieces. Common problem? Any hotfixes that look more decent than black duct tape and doesn't cost a fortune/take "for ever" to do? It doesn't have to work, the A/C works, but i would like it to stop leaking water, the winters here are pretty rainy...
How are the transmissions in these cars? The previous owner replaced it at 180K miles, now going on 290K-ish miles. First gear can be rough, but it doesn't slip more than what seems normal and acceleration is good.
The power lock servos actually work, but the locks seem to be too hard for them to push up and down (All of them). Will a quick lube of visible joints inside the door be enaugh to fix that or is everything closed up and have to be replaced?
Other than that the car seems to think it'* too cold here in Norway, the compass points south. Always. But watching a working compass on Norwegian roads would only make you dizzy anyway, so that'* ok. And the Driver Information screen is dark most of the times, but sometimes it lights up, does a few checks and concludes that nothing works, everything needs a service and all doors are open. So every time i start the car and that thing is dark, i'm happy.
Did the face-lift interior come in 89 and the exterior in 90? I've noticed some considerable differences in interior design and i was wondering if i HAVE to get a car of the exact same year and model if i want interior parts. Getting an LE or SE for interior parts seems like a waste of time since they aren't even remotely close to looking the same inside.
That'* all i can think of for now. I'll try to take some pics after i've cleaned it. Just finished a 40 mile journey on wet, salted roads. It'* more white/grey than black atm.
