Moin Jungs, have decided now to throw out my factory boxes and invest a little bit. I just want to use the existing recesses that would be there: – 10cm Front + HT – 13cm Rear + HT Both systems should not cost more than 150€ each and I would like to let them play only via the radio (Alpine 9812RR 4x60W max.). To get some pressure in the stomach, I want to expand my trunk, whether I don’t know now, but should seamlessly fit into the clan Is this possible at all, if yes, it is worth to install 2 subs? If not, I would need a final stage for front and rear, up to 200€. A sub should not cost more than 150€ and the appropriate final stage no more than 250€. My musical taste is mainly based on heavy metal, so I would like to hear a clean double bass if this is possible with a sub. Furthermore, the size of the sub(s) would be decisive. Prices sin d now roughly calculated, if there is money left, that would be very great hope, someone understands what I want and can help me further. Brands I prefer no, since I have no idea… Hold on, I don’t want to get called the name Magnat
