So it’s time for people, my age B3 with 70 hp should stay the same as it is. For that sound has to be pure that has washed itself. Of course money plays the role of the roles. Because without MOOS NIC LOSS So I’ll start… With the boxing: How would the performance be if I built a box… And how high can you bring the performance maximum, with self-built boxes. because completely new I can’t afford. Shouldn’t be small and should give me unique sound. Who can give me tips? n, pages where I know what I need for such boxes and possibly also some costs can specify.. The second problem: probably not so easy, I need an amplifier that has washed itself. Maximum 130€ to 150All at most… I know about amplifiers 0 and need your top opinion… And maybe you can also give me a pair of names where you can talk about since or where you can be satisfied… please also pay attention to RMS and OHM details…because otherwise I don’t look at them. The third and last problem… Sound is always nice, but what do I do with my battarie? I know that I have to connect amplifiers to the battarie, so now I’ve done it and turn it up full, I know my car has to be on it. Because otherwise my battarie is empty at the time I don’t want to. Is there a normal 12 V still enough? so would be nice if I could get a few of my own and TIPS. So that’s what I’m about to do. Thank you for all the help. So I say thank you because those who can help me would not be if I could get detailed answers.
