My rear speakers get interference from the throttle?

I have a mk2 furio 1.4, recently changed out all the speakers new head unit and amped the rear speakers. now for some reason the rear speakers get feedback which seems to range in frequency when i use the throttle.
Weird i know,

i have a jbl 400w amp powering 2 13cm 240w vibes and well there arent nearly as impressive as they should be.

i have had a look at my wiring and i used the grommet on the drivers side behind the pedals for the power lead this seemed to be to be the only available place to run the power lead? anyone else use a different one?
This is also where i think the problem is but i have no idea have to fix it. all the connectors are crimped properly and its grounded on a rear seat bolt.

Any and all ideas/views are welcome.

It is the ground mate, i had the same problem in my car, seat rails or things similar aren't that good for grounds. Best thing to do is find somewhere to bolt it right into the chassis. Hope this helps.

How hook amp up to a oem integration SNI-15 line output convertor


The amp needs an RCA input to communicate with the head unit. SOLDER the wires that come out of the head unit for the front speakers to the SNI-15, making sure that the polarity and right/left is correct. Do this for the front and rear speakers if you have a 4 channel amp. Cut the wires if you add new speakers and run the new wire from the speakers or sub box directly to the amp, or skin back the wire insulation and tap on if you use the factory speakers :( then plug your RCA cable from the SNI-15 to the input side of the amp. Don't forget that most new cars have their own amp so you might have to locate it and bypass the speakers wires around it. Don't make a mess in case you have to put everything back to factory for resale. You can avoid all this by installing a new/modern head unit with built in RCA outputs for front, rear, and sub woofer. I hope this helps. Ray

LED lights up but! ???


Sounds like there is a problem with the amp. Try switching the inputs around for that output on the amp. If that does not help, Yes I would have to say that there is a problem with the amp output circuit.

Dodge infinity


The Infinity system includes a CD/cassette receiver or a CD receiver in the dash, and a complement of 7 speakers: 3-1/2" speakers in the dash (left, right), a 2-1/2" center dash speaker, two 6"x9" woofers in the front doors, and two 5-1/4" speakers in the rear doors. You'll have to remove a section of the dash to install a new stereo, as you do with the non-Infinity system. You'll need a special adapter to connect a new car stereo to the Infinity factory amp http://www.crutchfield.com/p_120CHTO02/Axxess-CHTO-02-Factory-Integration-Adapter.html?tp=3486

This one Wire should be for the +. Try connecting the + to the Head Unit and - to a Common Ground. At the Worst, You will Blow the Amp Fuse if not Correct. The Lead from the Head Unit is Only an Off and On from the Ignition. Please Rate My Response! Thanks!

1999 Audi A4 Rear Speakers


The large block is a factory amplifier - in your car (as was in mine) you had a partially-amplified system. The front speakers were driven at speaker level from the head unit, but the rears were fed a line-level signal from the head unit to the amp, which then boosted to speaker level. The harness then sent the speaker level signal to each rear speaker.

What you can do is fit your new head unit. The fronts will interface perfectly with no issues. For the rear, run new wires from the adapter harness at the back of your head unit, back to the new rear speakers, and connect them directly. Then everything will work as it should.

Rear speakers in audi 1999 audi a4


You don't want to fit that - it's the factory amplifier for the rear speakers (the rears are amped, the fronts are not). You need to run new wires from the head unit back to the new rear speakers so that the speaker-level outputs from the new head unit are used to drive the new speakers.

I hooked up a 4 ch alpine amp MRP-F600. The back speakers play nice but the front speakers play very low. What could be the Problem?


1)When you connected the amp to the head unit, did you run two pairs of RCA cables for front and rear reference or did you only run one set of RCA cables from the rear out to the amp?  2)If that's not the case and you did ran two sets, on your amp, swop the rear and front RCA cables. If the rears go quiet and the fronts are loud you now know the issue is either in the cables or how the head unit is set up. If the fronts are still quiet, check your Amp's gain, frequency and filter setter settings (if available). If those settings don't change anything you may have a faulty amp. 3)Check speaker connections, seems trivial, but you never know.
Message me back if nothing works and/or you get stuck.

1998 Audi A4 Quattro rear speaker wiring


You can't use any of those - the large connector at the OEM speakers is because the rears are amplified. Your factory head unit puts out a line level signal to the rear speakers. There's an amplifier on the driver's side rear speaker (the box around the magnet that you can see from inside the trunk).

You need to either replace the head unit with an aftermarket one to drive your new speakers, or you need to tap into the amp connector and find the line level wires, break them out, put RCA plugs onto them, and plug them into an aftermarket amp, which you'd use to power your rear speakers. Doing it that way allows you to keep the factory head unit.
