Sound System
Hey I am about to put a very loud, very expensive sound system in my
’98 A4 1.8T. Before I start, has anybody done this and have any suggestions or things I should know about Audi? I am a professional installer and I know what I am doing, but have never installed a system like this in an Audi. So if anyone can think of anything that I should be aware of let me know..thanks. ps if you are curious about what I am putting in, here is a list: Eclipse 5423 Head Unit Eclipse DA6213 2-channel Amp (bridged mono RMS 1100w @ 4ohms) Boston Acoustics GT-40 4-Channel Amp (4x45w RMS @4ohms) Eclipse SC8254 Component Set (Front) Boston Acoustics NX-67 (Rear Coaxial) Two Xtant 12" X-Series Subwoofers Two 1.2 Farad Phoenix Gold Capacitors Street Wires and Rockford Fosgate wiring all the way around. -- Posted using the http://www.autoforumz.com interface, at author's request Articles individually checked for conformance to usenet standards Topic URL: http://www.autoforumz.com/Audi-Sound...ict123725.html Visit Topic URL to contact author (reg. req'd).

You may want to check out the audiworld A4 forums, there is always
discussion on sound systems there.... Do a search and you'll probably come up with what you're looking for.... Dan D '04 A4 1.8Tq MT-6 Central NJ USA |

Make sure you don't short the K-line to the aftermarket head unit.
Mechanics will blow their VAGtool if you do that. A lot of wiring adapter looms are miswired.

I'm sure you know this, but if you're planning to keep the original head
unit, its output impedance is not the standard 4 Ohms. I seem to remember it was 2 Ohms.

These days, any solid-state amp that costs over two bucks oughta have an output impedance measured in tenths or even hundredths of an ohm. If you mean that the Audi head unit is designed to drive a 2 ohm *input* impedance, well, that's a good thing, not a bad thing, and should pose no problem when driving 4-ohm speakers. Meanwhile, if you're talking about the line-level output impedance, rather than the speaker-level output, then 2 vs. 4 ohms ain't gonna mean a thing - the input impedances of today's separate amps tend to be up in the tens of thousands of ohms. -- Mike Smith |

Obviously talking about input impedance. In practical terms what this means
is that if you fit a pair of 4 Ohm speakers, you're only just going to get half the desired output (read volume), which is a real pain.

What's the point? - I'm assuming you already have the Gamma setup, in which case it *really* isn't worth changing it. -- Steve H 'You're not a real petrolhead unless you've owned an Alfa Romeo' http://www.italiancar.co.uk - Honda VFR800 - MZ ETZ300 - Golf Cabrio Alfa 156 2.0 TSpark - Alfa 75 TSpark - Passat 1.8T - COSOC KOTL BoTAFOT #87 - BoTAFOF #18 - MRO # - UKRMSBC #7 - Apostle #2 - YTC # |

Maybe not for someone who only listens to AM radio, but for an average audiophile there's a lot of room for improvement. Pete |

Well, speaking as what you'd call an 'audiophile', the OEM setup in B5 chassis VAGs is pretty damned good. A car is a pretty crap environment to listen to music, so it's not really worth spending silly amounts of money on 'improvements'. You'll only actually get more volume, not better quality. -- Steve H 'You're not a real petrolhead unless you've owned an Alfa Romeo' http://www.italiancar.co.uk - Honda VFR800 - MZ ETZ300 - Golf Cabrio Alfa 156 2.0 TSpark - Alfa 75 TSpark - Passat 1.8T - COSOC KOTL BoTAFOT #87 - BoTAFOF #18 - MRO # - UKRMSBC #7 - Apostle #2 - YTC # |
