Hey guys,
am going to be buying a mediocre second hand car soon....
as such im going to be installing some aftermarket
speakers,subs etc..
as the car is going to prob last for about 2-3 yrs.....
i am looking to install active subs, new head unit, 6x9's ,
and front door panel speakers.....all of it will be coming
out when i get a new car in a few years time..
i have researched and scoured the net for info
and how to wire it all up..
from what i have "googlearnt"
(please correct me if i am wrong ..any pointers would def help)..
the active sub still needs 12v power source running
from the car batt (fused) ...sub will need to be ground to the car
chassis...and on/off lead to head unit..correct ?
removing door panels to refit the new speakers,
...can these run straight off the headunit amp ?
would the 6x9 's also need to be grounded ? or do
they ground via the headunit ?...and would they
need there own dedicated amp ? ...if not is there
a minimum head unit amp out that is recommended for 6x9's ?
....bearing in mind they will also be running the door panel speakers
thanks in advance !
*** added this...its kinda how i se it in my head on how im going
to do the install.....if there are any obvious errors ..please let me
know***

Speakers today commonly use two hot leads and you can't ground either
from a HU, but power amps tipically use one hot lead, unless its
bridged, which means two hot leads.
You can ground speakers from HU's, but then you have to leave one floating
which cuts voltage in half or 1/4 power, not loud at all.
Power ground is attached to chassis, and its not good to attach speakers
to one side of ground. I,m not saying its impossible, but not
generally done today.
You seem to like 6X9's.
There is too much treble and midrange beaming from them torwards where they are pointed.
