  • Safety of spare parts supply (older models) – which manufacturer is the leader?

    Hi, since I prefer to buy older vehicle models (which are usually not produced at the time of purchase) and drive them for quite a long time, I would be interested in which manufacturers here guarantee a safe spare parts supply over a very long period of time and which manufacturers here leave the (youngtimer) owners rather in the rain. At Opel I have had very good experiences in the past years, at Ford and VW rather less good. How do your experience look like? and where is it special?

  • it250d or it300

    Hello guys, I want to finally get a SUB…but now I am again in front of a Dilema….so HERTZ I would best buy (as you ordered), but which is exactly better…es250d or it300….I calculated here and I got this at the end:ES250D box volume in liters: 75.4 marginal frequency f3 (-3dB) in Hz: 25 marginal frequency f8 (-8dB) in Hz: 21 efficiency in dB (1W/1m): 86 length of the bass reflex tubes in cm: 37.7 diameter of the bass reflex tubes in Hz: 21 efficiency in dB (1W/1m) cm: 10 Number of bass reflex tubes: 1 Total surface area of the bass reflex tubes in cm2: 79 Ql: 7 ES300 Box volume in liters: 71.3 Limit frequency f3 (-3dB) in Hz: 31 Limit frequency f8 (-8dB) in Hz: 25 Efficiency in dB (1W/1m): 89 Length of the bass reflex tubes in cm: 30 Diameter of the bass reflex tubes in cm: 10 Number of bass reflex tubes: 1 Total surface area of the bass reflex tubes in cm2: 79 Ql: 7 …what does “Ql” mean?

  • Laser noise in the LS

    Hallihollo. I changed my radio recently and since then I have a noise in the rear LS when the radio goes on and off and I read a CD. I didn’t have that on the old radio and I didn’t change anything on the wiring. Where can it come from at once?

  • Housing calculation Bandpass

    Hi together, as already described in another thread I plan to build a bandpass myself. The GZUW 12X from Ground Zero is to be built. Problem is now only the case calculation. I tried the whole with WinISD but nothing reasonable came out. Maybe you can help me with it. Use the dimensions of the entire box as well as the dimensions of the individual chambers. With the technical data on the chassis.

  • Help with the construction of a subbox with 2 Rockford P112S4 Subs (fluxwildly76 HELP)

    Hello, on recommendation from fluxwildly76 in another thread (http://www.motor-talk.de/showthread.php?…) I bought two Rockford Fosgate P112S4 Subwoofer. Thank you for the help and hope you can read with me and of course all the others. Now on the topic: I drive an E36 Coupe, no ski bag only foldable back seat. For the Subs I have to build a housing and I need help with the calculation etc. so that the Rockford 1. I’m not quite sure in which direction I should align the subs, whether to the passenger cell or the rear? 2. Should the box be divided into two chambers because of the two subs? 3 What wood is the best and how thick? Connection terminal I have to buy then. 4. Do I also need bass reflex tubes?? If so how long and how long??? I would like to build the case with a plexiglass wall in front of it so that the subs look good. mmen, maybe a few spike flow from the hardware store still with in to the peterde. How do I attach the Plexiglas best to the box? It is of course also about optical wants a small beautiful trunk expansion so to speak and of course also well Mucke, it is clear to me that not always everything can be arranged. I am grateful for any help, is really a very good forum!!

  • What kind of door?

    hi, the following question to the experts here: I drive an omega b caravan and would like to install a 20s subwoofer (possibly even a 25s, see) in the rear doors. per door, of course. since I was still active in the scene until 3 years ago, I am currently thinking of an emphasic neo for installation depth. however, I don’t have the thiele&small parameters at hand, or can I just conclude from this that they are suitable for the door installation. they should be put in a GRP board, like I installed it for the front, but still about the door volume running. until now there is a blue point Seattle MP74 as well as a GroundZero GZTC 2165T in the GFK board. it sounds very clean and powerful in my opinion. but since I hear mainly hardcore techno, there is something missing from the jagged bass. it doesn’t have to be loud, the times are over, but some support in the cellar would be nice. I prefer a closed box, but a box will be cancelled unfortunately. as a final stage I thought a box would be nice. Hifonics brutus who is born on 2 ohms as well as a 0.5F cap. I actually wanted to run only the 2 woofer over the level, because that radio is only about 60% exhausted, is loud enough. but keep out below, there was a lack…… does my calculation go so far or do you recommend me something else? (my stand the things has been as said up to 3 years ago, has happened a lot since then…..) thank you already. mfg, patrick.

  • After full fuelling problem at Piaggio Skipper 125 ( 2-stroke engine ) !!

    Hello scooter friends, have a small or bigger problem with my Piaggio Skipper Roller 125 ( 2 clock motor ). Whenever I have filled the scooter and put it there, it presses me or runs after a certain time gasoline on my rear wheel. I just can’t find where the petrol comes from. However, if the tank is only 1/2 or 1/4 full nothing happens at all. I have already checked all hose terminals and connections and also followed up. But it did not bring any success. . Can someone tell me where the petrol comes from ?? Or is this only the case with the currently high temperatures ?? Who has had this before ?? Please write me everything you know. Thank you in advance. Many greetings from Regensburg Klein_Kare Karl-Heinz Klein

  • Which carburetor Neos 50 2t

    Moin municipality, I just picked something up above because I don’t know the exact type yet. So, I got used Yamaha Neos 50 year of construction 2017, two-stroke carburetor with oil sockets and petrol filling sockets under the seat. Because the Moppi has stood for a long time and I don’t feel like cleaning the carburetor, I would like to buy and grow just a new carburetor with e-choke. Maybe someone from insiders might say what exactly that must be for a carburetor s? There are some with 12 mm up to 18mm. I don’t want to tune anything, I don’t want to do anything faster, I just want to run neatly and cleanly. Maybe your swarm knowledge helps further? Greetings of the Gardiner
