per our conversation. Mic your exhaust and add a couple

[Skibum]

do you have them already?

[Jay]

Jeeze Ski, we talked about them an hour or two ago and I haven't even taken the amp and a speaker to the local garage yet.

I wuz a jist a funnin' you.

Cheersh!

[Skibum]

thought you had 'em shipped "next hour"....

ive never understood bass shakers. They must be good since they are made by high end audio companies and sold for mucho money. I get plenty of SHAKE from my 12 inch sub (at home.. not car). I used to have the boomin stereo in my ride when I had my lowered rice burner truck, but no more...

partsexpress.com is running a $29.00 sale on 50-watt units.

I wonder how they'd sound in these?

[Skibum]

I use dual 12 inchers in a bandpass box for bass at my house... plenty to go around. I don't need no dumb vibrators to SIMULATE bass...

[Jay]

I thought you enjoyed your vibrator...

[Jay]

This one's mostly for Ski since he's not avail via EB at the mo. and we've been discussing this - anyone jump in tho.

Got a 13.8VDC PS and hooked it up to the auto amp. Connected a good spkr and portable music player. Sounds really good.

Now, does this look like the spkrs are floating a la current vehicle standards?
Obviously, ~7 below, is 1/2 the supply voltage.

~7VDC amp chassis to speaker + and -.
~7VDC from negative supply to spkr + and spkr -.
~7VDC from positive supply to spkr + and spkr -.
~5mVDC from audio input ground side to amp chassis. It appears physically isloated from the amp chassis.

So, what's the bottom line on connecting the amp inputs to my in-dash rcvr's subwoofer outputs w/respect to bolting the amp on the Jeep's chassis?
I don't see a reason to mount the woofers to the Jeep chassis because they'll need enclosures anyway.

On the surface, it looks OK to me.

[Skibum]

The OUTPUT of just about any power amp made is going to be floating ground. (AS yours obviously is)

[Jay]

Ski, you just tried to contact me. I immediatey replied but got Error: Remote user temporarily unavailable. You have no presence either.

[Jay]

The OUTPUT of just about any power amp made is going to be floating ground. (AS yours obviously is)

<{POST_SNAPBACK}>

Yes, but you were pretty sure that RS auto amps' spkr - and chassis ground were at the same potential. My measurement show they're not.

Or have we done it yet again?

I just want to know whether it's 'floating' in your parlance - is it OK to bolt it to the car chassis. It seems so.

[Jay]

Well yes, the short of it is that I can bolt this to the vehicle's floor as thought.

One big shortcoming of IMing rather than A/V to communicate is that long, typed responses can get lost above the visible chat window - unless you think to scroll up.

I suppose I'll use EB's full capabilities now.

[Skibum]

you mean you can talk????

[Jay]

If the damn thing will stop trying to reconfigure A/V devices.

Don't you go telling me to follow your directions to alleviate that. BTDT.

Don't go telling me to reformat again. I inherited this PC from my son and of course he lost the XP disk.

And, I don't want to tie you up when you're in support mode. All I can tell is when you're on the phone. I know you have a lot of emails and forum issues to deal with.
