Music part 1 :) — Toyota Celica, 1.8 liter, 2000

I decided to start describing the most precious thing for me, and just eat it in the car :)

The front doors, inside are completely glued with vibroplast STP and splenitis (splenium was not glued by me — then I'll re-glue :))

The price is 12100, this is from the manufacturer :) I found the same in Sochi only for 17300 :)

Dynamic in the front doors:

Alpine SPX-17REF

The Reference series was the first to go on sale and is available in two versions - with midbass sizes of 13 and 16.5 cm. the tweeter can be mounted on a special bracket. The woofer/midrange cone is made of aluminum and has a very high rigidity. The cast basket is devoid of overtones, and its profile and neodymium magnet reduce the installation depth to the minimum dimensions (for SPX-17REF - 64 mm).

The tweeter is brand new with a soft silk dome. Mounting accessories for flush mounting included. The crossover uses high-end capacitors, air-core coils and cooled resistors (!). The contact group is very convenient, it is possible to connect with terminals or under a “bare” wire.
