Hello guys, I would like to miss my car better sound. Among other things, the bass should come over better. Music direction 90 % Metal. Rest radio. Radio original and should not be changed. I would like to have the system built by the professional. At the first request was spoken by nem Aktivsub under the passenger seat. But am at the superior degree to let the doors dam and fetch a 16ner combo. For this reason maybe a 4channel and normal sub would be more meaningful? D a car is a 7seater with correspondingly little to no space in the trunk. Jmd ideas? Is there possibly jmd that has already installed something in the car. Budget as little as possible xD Hab but reckoned with as 800€ times. Thank you and nice Sunday. Greetings Thomas
