Ok, here are some pics of the new radio install on my 71 98. I left the original AM/FM radio in the dash.



I put the radio on the floor board in an upside down universal box. I wanted to put it in the glove box but that wouldn't have worked very well. I still need to use electrical tape and wrap the wiring bundle. FWIW, it doesn't get in the way of the accelerator and I wear a size 18 boot.



Sorry for the lousy pic but you can see the aftermarket speaker grills I installed on top of the front speakers. The original grills wouldn't work because the new speakers were dual cone and got in the way. Luckily the rear speakers worked fine under the package tray. The front grills do look a bit tacky but I didn't have to modify the dash so I am happy.



Here is the amp and subwoofers in the trunk. I mounted the amp using sheet metal screws that were abou 3/4". It's actually farther on the driver's side than the gas tank, so I didn't have to drop the tank. I could mount the subwoofers on the passenger's side out of the way of the tank but so far they aren't moving when I drive.

So, that was my Christmas present. It's the first time my Olds has had tunes since I bought it in 2009 (besides the 1 note drone of the 45 inch glasspacks).

I still need to tune my head unit and amp so the subwoofers perform as best as they can. I might check out a car audio forum. There are all sorts of settings like crossover, gain, etc. that I tuned with my ear audiometer (think butt dyno) but my hearing aid sort of gets in the way.

BTW, sorry about fat fingering the title of the thread. I posted it with my phone so...

 

Fixed your title, nice install.

 

Thanks.

 

That looks really good.

 

Your front and rear speakers should work just fine like that. As long as the front wave is separated from the rear wave of the speaker you will get the most out of them. Position of the woofer enclosure is what makes the difference for the bass. Try turning the speakers 180 degrees toward the side or facing them to the rear of the vehicle and I think you might be pleasantly surprised.

 

I'll give that a try. There is enough slack in the wires from the amp to the subwoofer that I can easily reposition it.
