Who has a huge stereo?

Yep, that's how it is done. You can also use capacitors if the amp input voltage is sagging too far.

 

Yep all the old stuff applies here too stiffening caps amplifiers unless you're running them wide open right regularly I mean you shouldn't really see any problems other than heavy high wattage used in these type of cars tend to flex the body and the plastics to the point of constant rattling sitting at idle and things like that so you'll spend a lot of time with the sound deadening material and glue and putting something in between interior panels and metal just to avoid rattling and vibration as best you can especially for when the stereo is off.

 

what do you like to use for working out natural resonance?

 

Yeah I don't get to spend a lot of time in the stereo world anymore My uncle worked for Hirsch Hoouck labs . In the '60s through '80s Lenny Feldman and Julian Hirsch did all the testing for all the good gear that stereo review reviewed for about 36 years Great guys good people My uncle was in the crew of people that pretty much invented four channel records and audio turntables that had cartridges on them and records that had four channels in them so left and right front and rear this is way back in the early '70s I believe I still have his record collection of four channel records which is I about 800 deep I think mostly progressive jazz and things like that stuff that I didn't listen to in the day. Those were some fun times

 

What I was getting at- do you use any special technique or tool to identify the natural resonance of a door or cabin? How do you test the results of the matting for tuning?

I've done plenty of custom car audio, but never any high wattage stuff, so I had relatively little clean-up to do in terms of rattles.

 

Yeah that's how I do it. I was curious if anyone was using measurement tools that might have spared me from disassembling/reassembling my doors 5 times lol.

It was still worth it!

Most any good stereo should be able to blow holes in the doors of a generation 3 All you have to do is kick them with your foot I imagine a large enough kicker speaker Paul to produce dents on the backside of the door on the sheet metal side not the door panel side I mean just leaning and accidentally pushing a body part against the door panel produces dents really easily it was almost shocking to me on the three on the two not so much.
