I’m an overcrowded carhifinub, who wants to be pro! so as the title says, I have thought up the following (the questions are numbered to keep the overview :P): in my 3er compact (silver) a magnat megaforce 2120 169€ – 350W or a magnat bull power reflex 301 79€ – 230W should be placed in the suitcase room. which would you prefer? (1) as a midtoner I tend somehow to an xplod of sony – pricey are all in the frame. I stand on sony! ^^ de r diameter may be a maximum of 15cm. from the deep I have no idea, I would have to take off the cladding. there are electric window lifters installed and currently 7cm Teller loudspeakers in the door (where the max. 15cm should be in). so now comes still a difficult addition: I also want to travel, then the bassbox out of the suitcase and then also the small speakers in the wall have to deliver good sound. enough there two from sony? or should I still somewhere tweeter or other midtones installed? (2) What do I need a frequency soft (3), which soft fits for my system (4), what do I have to pay attention to? do I have to change if I take out the bassbox? (5) the radio must be a brand radio, must be mp3-capable and have a rotary button for the loudness. since I came to the cheapest of pioneer 249€. matching red to the xplod 😛 sooo… now I would like to know which end stage I need to install all this z u. the end stage will then I think find a place in the suitcase room and should also look like something (suitable to the bass). (6) is the maintenance-free bmw bacteria with 50 Ah sufficient? (7) again a very general question: do the medium and tweeters also run over the end stage?(8) if yes, I would have to put the audio cable first in the suitcase room and then back to the front to get into the side doors. is that so easy? (9) on the radio description is 4 x 27 WattRTS . then all four cables go to the amplifier or is one enough?(10) does that go to the end stage? does this work like a frequency soft? or does the joy double come behind the end stage? (11) so I hope one of mine takes care of it, otherwise I run through the internet for another 3 months and am in vain looking for reasonable tutorials/responses. in this view already BIGTHX!!!!!
