Bought speakers. — Toyota Carina, 1.5 liter, 1992

At the beginning of the summer, he changed G.U. from mystery to Pioneer 4200SD and recently changed the front speakers, replaced the regular burnt ones with a component JBL GTO 6508C.
Installed without an amplifier in regular places.

But the trouble is, the speakers do not give out low frequencies at all.

I will try to put spacers and plan to pick up an amp in the near future.
