FAIL = new Rockford Fosgate amp and Door Speaker combination!

[cp_stunna_2011]

I am having issues with my Rockford 300-4 prime series amplifier and punch series door speakers. They whine like crazy when i rev the motor and it is really irritating i have tryed everything to fix this problem, and im not kiddin. If ANYONE has ANY advice it would be LOVED, because this sux BIG time. Thank you. Hit me up with whatever ideas you may have that cause this AND HOW TO FIX IT

Sublimewind should be able to help you out, my guess would be the ground, but I've been out of car audio for years, I couldn't tell you the last time I wired up seperate amps to speakers or a sub...

This whine you get, does it follow the RPM of the car? You have a ground loop, weather it be from the HU, or the amp ground... RF Prime gears is bottom of the barrel, I just spoke to my friend that installs at ABC Wearhouse, they are getting a rather high failure rate with them... beware.. Now, you say you've tried everything, what is everything? Do you have the amp mounted to metal or wood? How is the amp grounded? I would assume the HU is grounded through the factory harness?

[cp_stunna_2011]

nope the HU has its own seperate ground that i just installed directly to the chasis. so get rid of the prime amp and trade in and upgrade to a punch series, and i geard thay prime stuff was gong down hill to. Anyway i also uprgraded the battery ground to 4 gauge. The amp is mounted on a custom cut/molded piece of tinted palstic beneath the passengers side seat. and i have looked into this ground loop but dont really understand it? Could my pioneer deck be the problem i heard they were notorious for it. i Have also tried a few other things like switching rcas with brand new ones, thjey are run on opposite side of the battery cable. i also left one door speaker hooked directly to the deck just for testing purposes. Here is the next thing i am trying today: http://www.caraudio.com/forum/...98477

Here is the next thing i am trying today: http://www.caraudio.com/forum/...98477A. not all chassis grounds are the same, could be an issue, hard to say.. B. The Prime stuff may or may not be junk, it's hard to say, it's the entry level gear... C. Upgrading the battery ground was a good idea, doing the motor to chassis ground would be another good one.. D. The amp mounting, is there a change that one of the mounting screws FOR the amp is touching metal? Are the mounting feet for the amp metal? If so, you could be creating a ground loop that way... try dismounting the amp and putting a piece of wood under it and test again.. E. A ground loop is created when 2 (or more) grounded components in the system are at different ground potential... Say the amp ground isn't as good as the HU, well that difference (a potential difference, like what makes batteries produce power) is what causes a ground loop... This is why it is important to remove the paint around an amp ground connection (along with applying dielectric grease) and make sure it's good and tight.. F. Pioneer IS known for RCA issues, search Pioneer Pico Fuse... On the pios, they have this "Pico fuse" attached to the GROUND of the RCA lines.. well, one wrong move and the fuse blows, or opens.. Leaving the RCAs UNSHIELDED.. Well, this is where the problem lies... Here is something you can easily try...

[cp_stunna_2011]

k that audio forum stuff worked with the rca copper wiring. everything is good, and if i upgraded to the power series amp or punch series amp i would just end up turning the gain down becuase all the power that i would get i dont need. i mean if i really wanted to i couldupgrade but i deam it unneccesary. and the screws i used in the amp mounting i grinded off. there is no metal touching ne where other than the ground.

[cp_stunna_2011]

i think i may spring for the power series amp, just so i can say i have the best pf the bestin RF amps and 3 way door speaks lol and it should run with noooo problems.

[ajflan]

Yes the RF prime series is their entry level series, but they arn't that bad at all. I sell car audio at ABC, and we havn't had that many returns on them. In fact, I am using a prime amp to push my Alpine Type R components, and the amp pushes them quite well.

[skylinedrifter]

My Infinity amp whined like colicky baby at first but I dropped in a couple of noise canceling dohickies at the line-in inputs and the whine went away.

[cp_stunna_2011]

nice, and yeah im prolly gunna upgrade to the power series 4 channel and get a kenwood flip out just for hoots and hollers

I just spoke to my installer friend at ABC and he said they had more problems than that.. hmm.. dosn't matter, if it work, it works..

[cp_stunna_2011]

yeah well it powers them perfect u cant get any better than perfect power and thats what im aiming for....

[Sublimewind]

Of course there is better out there... there is better in the RF line... Explain to me what "perfect power" IS and I will explain to you why you are incorrect.. I'm trying hard not to be a jerk here, but, it's not easy at this point.. I just have to remember you are young, still learning...

[cp_stunna_2011]

well yes but no i like the way they sound, they can prolly be powered perfect by the power series 4 channel, so yes that is right lol i just dont see the reason. Do u think it would make them reach their full potential if they were hooked up to the power series 4 channel? Cause i also dont want to buy to powerful of an amp and just ending up turning the gain down so i dont blow them, eerr idk i just bought what i thought would make the speakers reach their full potential im going with RF throughout my car for mids, highs, and mids and highs power, so i am going to go with one of their 4 channels...

[Sublimewind]

Hay, i'm glad you didn't take that wrong, I came in out of the garage just to post because I was a bit harsh in that last reply.. My apologies.. Now as far as powering the mids/highs... Well, being that the prime line is the entry level, it may make it's rated power.. lower level amps are usually over rated, so you feel you are getting your monies worth, though it's a basic amp... As you go mid level, they tend to generally make rated power..Upper level, is usually under rated.. I think I've gone over that before... WELL, your prime 300-4 is rated for 50wx4 @4ohms... It MAY make 50wx4, but it would only be making it at the very upper volume levels... Throw a Punch p400-4 or better yet a Power T400-4 on there (40$ difference between MSRP) and you will make rated power + some... So, what does this mean, well, you won't be at the amps ragged edge, trying to push max power all the time, the amp will run smoother, sound better, make and/or double rated power.. Cheaper amps simply have less on tap, overall... My RF Power 1000 5ch was rated for 50x4@4ohm and 300x1@4ohm... It would do 111x4@4ohm and 698x1@2ohm.. So at mid volume, I could be pushing a solid 50w with plenty to spare, while you would have to be at near max volume, to be pushing 50w and you would be at the amps output limits... So, overpowering, with less gain, is far more beneficial to good sound than you might think..

soo i will probably upgrade to the power series. Then i will have the best RF 4 channel amp lol, cool. and my door speakers were the only RF door speakers that were three way 6.5s i could find, so not to be cocky but i got the best RF door speakers too lol. anyway i am going to get a flip out soon here so that will be cool.

T-1652-S.. http://www.rockfordfosgate.com...tatus=I'll get into why a simple 2way component set, will sound better than a 3way coaxial another day, it's late, i've been puttin down some beers... Till then.. Cheers..

[cp_stunna_2011]

yeah i saw that, but i wanted a different set of tweets than the ones that came with that package and why Rf didnt combine the tweets i wanted with my three ways beats me......anyway, im not always going to have subs all the time and becasue of that i was told to get a full range speaker, instead of a two way, and i have a couple of good audio buddies who have these and say they are actually better to combine with sysytems too.....one guy has 12 15s and the other guy 12 12s lol

[cp_stunna_2011]

im having a hard time finding the RF tweets i wanted right now i swore they were on there yesterday...oh well they are sweet. im putting them where u said to, right down buy the kick panel. or within a foot of the speaker.

(mainly in the crossover) I don't know where your "buddies" are getting their info from, but they really aren't doing you any favors.. Because one has a pair of 15's and the other has a pair of 12's DOESN'T MEAN JACK....

[cp_stunna_2011]

idk maybe do u think its worth it? i want to be able to hear my highs over the subs, idk wat im doin yet lol...

I lose my head... totally not your fault...You want to hear mid-high over your subs... Ok, we have a starting point... First off, you would be better off with a simple component system... 2 mids, 2 tweeters and 2 passive crossovers.. Getting the tweeters out away from the mids and facing you a bit better would help.. I have my tweeters mounted on my kick panels (for now) so that they are more "on-axis" Highs are VERY directional (think of the light of a flashlight), so having the tweeter pointing toward you can be very beneficial.. A component system will usually offer a MUCH better tweeter too... often times with a much larger motor structure... This is the Pioneer set i'm running in my car (just the mid)and the tweeter.. It's in a machined aluminum housing..!!Comes with an awesome passive crossover too.. You could get the above set for ~250$ depending on where you find it... At the same time, people LOVE the Phoenix Gold RSD components set and i've seen them go for as little as 40$... Maybe you should consider moving away from Rockford mids/highs and onto something more suitable? (RF isn't "known" for their top quality mids/highs, subs and amps, sure, but not the rest)

[Sublimewind]

I could almost guarantee you better performance with this component set...for THAT money..! http://cgi.ebay.com/Premier-TS...0.m14

naw man i love pioneer but im trying to keep it fosgate, all i need is tweets if i need those at all....

[cp_stunna_2011]

i currentyl have 4 3 ways in my doors as well as the prime amp so there is no getting rid of that. Im not going fosgate with the subs or sub amplifiers i will probably do hifonics amplifiers and alpine or some other subs.
