Musical troubles - logbook Toyota Carina ED 1995

I thought for a long time whether it was worth it and yet I decided I would make a loud car. First of all, the JBL GTO1200B itself and the VCL Lighting Audio for 6k mk were sold, the head in my car did not allow me to install this device. So all this was sold on the same day as the announcement was made, and even without bargaining, there were many who wanted to buy, the first who bought it all decided not to bargain ... Having 6k + a small amount on hand, I began to choose an intelligent head. The choice was between Pioner Alpine Clarion. Weighed the pros and cons and decided to take Alpine. I did not understand Alkah and had to shovel a lot of information to decide. On all forums, he praises such legend models as 9812, 9853, 9855, 9887, etc., but the problem was that these models were discontinued a long time ago, but even used ones are quite fun... to my liking, although it has 2 liners, unlike the 56 model. I took it for 6600 in a stereosib and I don’t regret it a bit, the sound is really a class of settings, too, enough for a beginner like me)
At the moment, the plans are as follows:
1) Shumka
2) alpine swr 1242 din + homemade case for it (50 liters 38 Hz)
3) VCL monoblock for subwoofer (I haven’t chosen which one yet)
4) speakers in the rear shelf are the same as in front and namely Lanzar VX830 (very solid bass speakers.
5) 4 ducts per speakers + Y connector TC linear only 2 :)) That's all for
now ... but something may change.
