Hello, please don’t laugh at me or curse me the bones for the following questions 🙂 but I have little to no idea of car sound and am glad to have found such a forum. So long speech short sense. I have a Golf 3 which is currently equipped with the serial LS in the dashboard, a Pyle 290W and a 6 year old (heated) Infinity Cappa 1.0-3 way. The radio is a Sony CDX-CA850 (4x52W/4Ohm) Now I thought it was time for what newer. I imagined: a 2 way system(“Kombi-LS” for in the doors and again a 3way into the storage. For the Alage I would very much like a new power amplifier with a little more power, but it should not rob so much space, because I do not want to reduce the trunk volume very much. For this reason also in no case a SUB in consideration. Does it then make sense to use the “old” amplifier for the front LS? Or is it enough to control it via the radio ? What is the meaning of using the “old” amplifier for the front LS ? e Dimensions of power (W) should I choose the one for power amplifier, front LS and rear LS ? What do you mean ? As promised the volume for the “extension” amounts to max. 500 teuro ! I am grateful for every tip and for every purchase recommendation! Greeting from the Saarland !
