amp install

Hi, im having a problem with sound quailty,I hooked up my player to two amps a 1500bd fosgate for base hooked to the rear rc on the riocar and I hooked a 800 h2 to the front rc . the problem im having is the EQ is not recognizing the front from the back and im getting base thru my highs.Is there a better way to hook up the riocar when using two amps

Please be more specific. Not sure where the problem lies. I'll take a wild guess based on the sketchy information given:

If you are trying to use the 4-channel equalizer in place of a true crossover, (by cranking down the low frequencies to your front speaker pair) you will create "holes" between the bands where some bass still leaks through.

This is because the EQ deliberately narrows the bandwidth of each band as you crank it farther away from zero. The solution is to hand-modify the Q parameter so that the bandwidth is wider for the "cranked down" bands.

HOWEVER PLEASE NOTE that there is a bug in the beta-11 EQ where one of the two channels is not properly saving the Q parameter in L/R locked mode. This will be fixed in the next beta release. In the meantime, use independent 4-channel mode to set independent Q's until the next release.

There was also a bug where 4-channel mode wasn't getting set properly at power-up, but I think that has been fixed in beta11.

Personally, I found it easier to simply buy an amp with a built-in crossover. They're not that expensive these days.

All try to be more spicific,Thanks for replying my amps are brand new it is a 800 two chanel amp that the front rc of the rio car are hooked to.The 1500bd amp is a one channel amp hooked to the rear rc of the rio car and ran to two 10"solarbarics.The 800 is running the mids and tweeters.Im runing 1.03 in the riocar

I called the the place that installed my riocar and they told me that the riocar is not designed to be a stand alone unit,and it would sound better If I got a second head unit and ran it thru the aux in of that unit.

Do the amplifiers have any built-in crossovers? Is your problem specifically the "bass gets into the front speakers" problem?

If the amps have built-in crossovers, my recommendation is to engage those crossovers and place the player's EQ into left/right mode rather than 4-channel mode. Center everything and see how it does.

I called the the place that installed my riocar and they told me that the riocar is not designed to be a stand alone unit,and it would sound better If I got a second head unit and ran it thru the aux in of that unit.

This is an incorrect statement. The Rio Car is, in fact, designed to be a stand alone unit and does (in my opinion) work the best that way. This is the way I run it, and I get fantastic sound quality out of it. Many other users here on the BBS will attest to that fact.

The amps have setting for the megherts and there set at 150 thats as high as they go. they dont have a regular croosover

Thats what i told them that it was designed to run alone.Maybe a bought the wrong kind of amp.

Do you have a digital camera? Or better yet the model numbers of the amps so we can check out their specs for you?

Sounds like you've just got the crossover set backwards for the front speakers. Does it have a switch that gives you a choice between LPF and HPF? If so, make sure the front speakers are set to HPF.

all check out the amp settings and all post some pics.I have been playing around with the EQ and im starting to get it to sound a little bet better.

Is what's described in here and in this PDF document what you have?
(Looks like the RF Punch 800.2 has the same filter switch/crossover frequency setting dial too)

Look at page 12 (you'll probably need to zoom in somewhat) and there's a switch
HP/FULL/LP (also see attachment). Make sure it's in the HP setting (HighPass, will only let higher ferquencys through) Then use the crossover frequency dial to set how low the HP filter will go.

You will get that from most car audio places. I feel the reason they tell you that it would work better as an AUX vise a standalone is because the Rio doesn't have a built in AMP but if you look at the specs of most of the head unit amps the THD is usually really high and besides most car stereo places don't even know what the hell a Rio Car is so they just tell you that out of "lack of knowledge"

thanks for the help everyone is giving me this forum is the best.I just got home from work and i havent had time to work on my system yet.after i do all let you no how it turned out. Thanks agian.

been messing with the EQ got it to sound a hole lot better.the only thing that is wierd is when i have EQ on four channel front it adjust the base and when it is on rear it adjust the hi's and heres a some picks hope they look all right.

sorry dont no to much about cumputer cant figure out how to post pics

The 4-channel bass/high thing was a known bug in one of the software versions. What version are you running?

im running 1.03 and tried to post pics but im a cumputer moron and cant fig how. lol

pic try agian

any one live in california that can call me collect and walk me thru a computer prob.LOL I work in construction and I dont no dick about computers.

Picture problem is probably that it is larger than 100.000 bytes - the board only allows posting pics of size < 100.000 bytes.

Is this an arbitrary limit coded into the bbs or something paul set? I'm wondering if maybe 250,000 bytes would be more reasonable, as the only times people attach stuff is usually a picture.

Calvin

The limit is hard-coded into the BBS I believe.

I think the problem isn't the size of the limit, part of it is that the text telling the user about it isn't easily readable. It should say "100k" instead of "100000 bytes".

Also, one of its major problems is that should give them an error message and allow them to re-upload if they exceed the limit. The fact that people can post and think it's OK because they're not prompted for a re-try is really the root of the problem.

Is it 102400 bytes or 100000 bytes?

Calvin

Good point.

Still, it should stop them if they go too big instead of letting them think it worked.

does that mean i should set the picture quailty lower on my camera.

No, it means you shoud resize it to a smaller image, using a piece of photo-editing sofware, before sending it to the BBS. Make sure the file size is under 100k before doing so.

All my pics are at riocar.org

When you say you are getting bass through your highs, do you mean throught the tweeters, or through your entire front stage? If it's through your tweeters, you definately need a capacitor (crossover) to roll off the lower frequencies, otherwise they'll distort very badly and you'll cook them!

Just a little thing to check :-))

I also run my empeg (rio-car) as the only head unit in my car, I use an xtant amplifier with built-in crossovers.. it's highly doubtfull that you have the wrong amplifiers, since the empeg is designed to work with almost all car amplifiers.

the problem is the crossover settings for your front speakers, as other people have said.. the EQ is not designed
to be used as a crossover, and is not designed to work in the way you are using it.

you simply need to adjust the crossover settings on your front amplifier, and rear amplifier to get the desiered output. a local best-buy car tech should know enough to be able to adjust this.
