Working on stereo but finding difficulty getting info… this car isn’t very ‘aftermarket stereo-friendly’

As soon as you add subs, it rattles… there was no pass-through… no fold down seats… the trunk is like a sarcaphogus until you cut…

And the amp in the trunk is only a two channel for the underseat woofers the rest of the speakers are powered off the head unit, meaning to amplify the rest of the system it has to be rewired (or wires re-run)
