Slightly OT but since putting on the soft-top I have noticed my satellite reception has gotten a lot more spotty. It cuts in and out way more often. Heck I don't even know where the satellite antenna is on our JKs.

I just had the hard top off for the first time yesterday. As I was driving along I turned up the radio volume a bit to see what all this hubbub was about with the reduced volume when the top was off.

I had to stop increasing it when it got up to 27 on the volume meter because it was WAY loud at that point. I can't imagine anyone wanting it any louder. Was this a pre 2013 issue or something? We have a 2013 Sahara with the 430N, if that makes any difference.

Tried out of curiosity as well. Noticeably better without the fuse in. I have the base system so no amp. Guessing it alters the amp output since I got worse results. '13 JKU.

Something I noticed today since putting a soft top on a few days ago. I was driving home from doing some errands and when I came to a stop it seemed like the music got quieter, and then as I sped back up it seemed to get a little louder. Now I know my wife's car radio has an option to do just that, low volume when stopped and then when it gets above 40 it will get louder to adjust for road noise and such. I am just wondering if this is something built into the JK when you unplug the connector for the hard top?

Has anyone else noticed this happening? I do have slight hearing loss due to job related noise, but I swear, I heard what I heard this morning.

I had the feature in my G35; it's called "speed sensitive volume" I haven't seen the feature on my radio- 2012 JKU

Ok, just a little follow up. Just came back from getting a hair cut, and I am positive that the sound got quieter while I was stopped and slowly got louder as I sped up.

Like I said before, I wonder if this isn't built into the system to work only when the plug is unhooked. And by jumping the 2 wires it is defeating that feature and making it louder all of the time?

Ps, I do have a 2013 JK...don't know if that will make a difference or not.

I don't like SSV, but I could see it making sense in "top down mode" mode.

I guess I could pull the plug on mine and drive around to see if the volume changes (since my hard top is still on).

First post, long time lurker.

This is accurate. It does have SSV. 13JKU here. Not sure if that's a 13 thing or not. But it's quite obvious to hear.

^I was topless yesterday. I had pulled the jumper just to give the "correct" version a try. I noticed that my sound was slightly different when I had stopped. Not sure if it was SSV (maybe a very mild SSV), but it was indeed something. I'll pay more attention from now on....I didn't know if it was simply windnoise drowning out bass at first.

12' doesnt have SSV with the 430N from what I can tell. Unless you have a setting for it or its in your manual, I would think you dont have it either on any year.

I too could not hear the music especially since I drive my JK from May to October without a top or doors so I replace the oe speakers with alpine and added an alpine amp and an infinity powered sub woofer in the back. Now I never need to raise the voulme past 25 as it sounds great even on the highway. The whole change cost just under $1000 and it is worth every penny.

So I've paid more attention, and yes, I do indeed have SSV. I've always hated SSV, and I hate it even more that it is in my Wrangler. Not sure if it is a 2013 thing, a soft-top thing, or a 430rbz thing. No matter what...I don't like it.

I'm pretty sure there is a way to turn it off.

Bumping this topic with some new data. I just upgraded the sound system in my '13 and came across this thread in an effort to improve the sound quality.

I am running the following:

Factory 430N
Factory amp feeds:
Audio Control LC7i
JL Audio HD 900/5
JL Audio C3 Components
JL Audio C2 Coax
12" Adire Audio Brahma in a ~1.25cm3 sealed enclosure.

I have my hard top stored and have the premium soft top installed. I made a small jumper as detailed on page one of this thread. I installed it and there was a noticeable increase in volume. I decided to test the output to make certain there was actually a change in the level and not simply a perceived difference.

I will point out that this test was done in my driveway using less than professional quality testing equipment. I do have access to an Audio Toolbox and a separate spectrum analyzer. I may perform the test again using better quality gear if I get motivated.

For this simple test I downloaded an app on my iPad from JL Audio that provides a simple SPL meter and spectrum analyzer. I also installed a pink noise generator on my iPhone. With no jumper installed, I ran pink noise at a level of approximately 86db. Without changing anything else and the pink noise continuing to play, I installed the jumper into the plug. The audio cut out for approximately one second and then returned at approximately 91 db. It remained at this level and did not drop.

In my Jeep there is no question that there is a real change in audio output. I will perform this test again in the winter to see if I get the same results when I put the hard top back on. I also would like to find out if this is simply a 5 db drop in output across the entire spectrum or if certain frequencies are being limited more than others. I'll try to get some screen grabs up from the Audio Toolbox when/if I test again.

I thought I would provide one additional follow up to this thread. I ran another test with pink noise and a spectrum analyzer. I ran this test C weighted with a 3s delay. The numbers below are with the jumper in, the jumper out and the difference between the two. So at 25 Hz the pink noise level was 67.8 dB with jumper in and 65.7 with jumper out for a difference of 2.1 dB. There is a fairly substantial drop between 200 Hz and 1250 Hz with the jumper removed.

Sorry about the formatting. I tried several times to clean it up but the text editor keeps smashing the numbers together.

I'm sure the thinking behind the "cap" (if there truly is one) is so you don't blow your speakers by feeding them high THD levels because you're trying to make up for loss of volume with the hard top off.

That's why I replaced EVERYTHING. Now I get tickets for jamming "too loud". I told the officer that I couldn't hear &(*% because I was driving on the freeway and thus it didn't sound loud to me. Got a fix it ticket anyways, it was only at 1/2 volume lol.

By the way this is how the stereo systems on Harleys work. My 2010 Street glide works in this fashion, when i am stopped it lowers output, once i am rolling it raises output. You are probably correct that when jumping the system you may be by-passing this feature and the output just stays raised.

It may just as likely be two separate things -- a default level of gain and how much gain is applied in a speed sensing increase, the latter is usually adjustable through the stereo.

This fuse solution still working well?

Wow, that is substantial considering that those without a sub, that's the majority of the frequencies you're getting. Also, remember that a 2dB increase/decrease is the same as doubling/halving your amplifier power. That's a killer conclusion. Thanks for doing this.

For those who have used this shortcut to boost audio levels, has there been any impact on the operation of the rear wiper after reconnecting the plug to hardtop? Seems to me shorting out an electrical component would have some negative affects.
