Hello people, once again I have to bother you with my strange questions. So, and that’s about me arguing with a colleague about whether a car is spending more time when a thicker hifi system is built in and if it is fully turned on. what do you think about it?? (please don’t laugh. I know that this is a funny question, but I don’t really know the right answer now) I just remember that a colleague said to me that he was looking at me. used in car more when it turns on the air conditioning…. mfg

Hi Folks ! My Clarion has arrived today But now I still need adapters, because the standard plugs in my car do not fit. I drive by the way a Opel. (but not for long ) MfG, m4rc

Hey, to all freaks with a fault-free front system… I used: -The search function. -Speakingly, trying to get rid of the fieping in the tweeters of my neck, just like at the beginning, when the components were new, everything was still as pure… -The speed-dependent whistle was also short-term away, but then I heard a slight, also not to be underestimated basic whistles, deeper, and no more speed-dependent, as soon as the ignition started! I have had the mass of the radio directly on the battery, I have taken the power stages from the rear seat so that they have no contact to the mass, I have re-grimmed and screwed on the mass connections, I have put both power stages at a single mass point… – Result: NIX!!! What can I do now to get these two types of whistles away?! That completely sucks the fun!!! Help me!!! P.S.: JVC radio, Canton-QS system, 2-fold shielded chinch cable, Fiat Punto…

Have bought me a new system! Radio Avh-P6600DVD front system Hifonics and in the Koffreraum Hifonics ZX12 Dual power amplifiers Crunch and Alpine! have now connected everything to the rehearsal! now I have in the Fronsysten at all no kang anymore and a hum when I turn out the loud strength and give a whistle at the gas. and back I mean the trunk rides it *ggg*, but in the interior almost nothing to hear from the Woofer!! Help!! Gruss jens P.S. Drive a Bmw E36 Coupe

Hello guys. OT: I don’t want to be a troll thread, I’d only be interested in what you’re pushing in your constellations with steps, subs, current and especially cars like that. I’d just like to know what you’re pushing with which car (it’s clear you can’t put it all down) and hardware like that. Would be supi of you if you were writing what you’ve got in sound pressure. I only measured it last Saturday. (Termlab old) There were 145 dB in the Audi A4. What do you have? Many greetings from Frankfu rt

Hello ! I have decided for a soundboard, I know the opinions go far apart but my decision has fallen. Now I just need your opinion on this soundboard : Pullman RS 6 3-way (triaxial) system It is neatly mounted on a stable MDF wood panel ! The range of soundboards is very large, I have the feeling that this is already something good !!! OR ? What is the soundboard in your opinion still worth ? It is used but in non-intelligent condition and ! Thank you for your numerous objective answers Greetings OnKeL

what happens if you switch the pole at the ls over a longer period of time? so about 1 year long…

Hello freak I bought the hifonics atlas final edition and installed it yesterday. this drives my hifonics zeus bx12 dual bandpass in the 2 ohm operation. from the very beginning I was not very excited about the performance, because my previous stage made slightly more steam with the sub. it is a JBL GTS 600, which fired the sub with 2×175 watt RMS @ 4 ohm before. on the way to work I took the atlas a little bit, after about 20 minutes was sc hluß: the thermal overload protection had jumped in. after about 2 minutes the thermo protection had calmed down and I had bass again. I had arrived at the target meanwhile and looked immediately. the part was hot like a stove plate here still something to the connection: supply from battery to amp about 30 cm, cross section 35qmm, everything exactly like with the jbl:http://home.arcor.de/abraserver1/gallery/mai05/web/img_0047.jpg (I have a capacitor, should be retrofitted) vors the amp has only 60A ANL, has to get me a bigger one, but that shouldn’t be the problem here…… where is the problem, is the amp defective? impedance problem I closed out, the zeus has minimum 2x 3,8ohm and the atlas is 1 ohm stable. here are test reports and instructions for the amp and the sub:http://www.audiodesign.de/downloads.htm one is disappointed……

Hi I have the problem that I have a subwoofer that should be driven with 2x4Ohm!Here are the data: Technical data: Frequency range 21-1000 Hz Impedance Loadability 500 watts Diameter 38cm Peak load capacity 1000 watts RMS chrome Flame design Double-swing coil Chrome-plated pole plate Foam bead 4 layered walkers Fiber Membrane 500 watts RMS 21- 1000 Hz up to 6.2cm Hub AW1571T 15 SubWoofer 38cm Flame Woofer 2x 4Ohm 60Oz Magnet 93,4 My amplifier has this data: · Sinus power at 4Ohm: 4x 50WRMS + 1x 150WRMS · 2 ohms load stable (with even more power) · total 700 watts maximum power (4x100W + 1x300W) · Tri-mode capable · frequency response: 5 – 24000 Hz · distortion factor. 0.05% · Cinch- (230mV – 8V) and high-level input · adjustable low-pass, continuously adjustable from 400-200 Hz. · Subsonic filter at 30 Hz with 24 dB · adjustable high-passes, continuously adjustable from 40-200 Hz. · MOS-FET PWM switching power supply. · 24-carat gilded connections · PTC overheating protection · Size approx. 215 x 65 x 460mm fits that or what do I have to take into account? Do I have to give something or another amplifier? Here comes number 2: What should have more watts of the amplifier or the boxes? What is an impedance? (Have heard the word about Car Hifi) Hope You can help me!
