To know whether you car has a factory sub you can call your manufacturer and ask him. The manufacturer will give you a correct answer for the same.
Factory sub is 8"
on factory actor on usa or on Europe the plaisio stores
The factory amp is located in the rear of the truck right behind the factory sub,
Well, i only know how to answer this because i blew the sub in my 2003 suburban. first go to the back of the car and remove the plastic bolting on the drivers side. about 10 inches from the back lift gate theres a cutout for the sub. order a new 8 inch sub from (sonicelectronix.com) there like 40 bucks. and make a easy install. works better than new.goodluck
Not without some serious and very expensive modifications. With another 300 H.P. you might be able to have a 10 second car. There are no factory built 10 second cars that I know of. Even a Corvette and Viper will not run in the sub 11 second range.
It's a sub frame car.
Your question is unclear. Factory parts are factory parts. Factory Equivelant parts are after market parts.
no you can not call the factory and order a new car
As you do not even list the make of your car it is impossible to answer. But as an example the Honda Accord can be purchased in 8 different sub-models.LXSportEXEX-LEX-L with NavigationEX-L V6EX-L V6 with NavigationTouringNeed to know the year, make and model of your car.
Yes. It is an option.
I am not sure about the volume, but definitely you will have either better or worse quality. Getting a sub will raise volume.
as far as i know there is only one amp and it powers the sub woofer. it is located in back, in the panel beside the sub woofer. pull off the panel covering the sub and look up to the left of the sub and there is a little gray metal box and a wire going from it into the sub box. the little metal box is the amp.
