[Mk2] [Turbo] Rev1 Turbo - Would I need a capicitor?

[IMR2T]

I'm replacing all the speakers with components and was aiming to run them off a 5-600watt 4ch amp along with the sub(or a new sub).

I've noticed when I put the window down there's a small drop in revs tempoarily.

I know nothing wiring an amp etc but I'm keen to learn.

With regard to the car being 25yrs old would I nd a capacitor or will the altenator etc be ok?

No system ever needs a power cap There a poor work around for not wiring a system properly.

If you find your getting significant voltage drop with your setup fitted then you need to upgrade the big 3 wires to bigger cables. your 600w amp us probably going to be 300wrns at best the stock wiring should be fine with it.

Interesting.

Sorted. Good to know

I haven't bought an amp yet, what are the 3 big wires?

[thomp1983]

There battery negative to chassis, engine earth to chassis and battery positive to alternator, they want to be a minimum of 4awg cable 0awg is preferable, welding earth wire is a cheap alternative just add extra runs alongside the factory cables

Sorted, thanks for that mate

I cheated and instead of running an extra cable from alternator to battery I used the battery to starter cable Toyota fitted. So went from alternator to starter with 0gauge
