If i want to upgrade my car soundsystem wat do i need to buy? like do i need to buy amplifier? or just subwoof?

-Okay so my car, one of the speakers in my car doesnt work at all. SO bascially i need new speakers, but i always want to upgrade the bass too



So all i need to do is buy a new pair of car speakers, and the subwoofers? or what elese do i need? Do i really have to buy an amplifier too? because the money piles up pretty fastCheck out sonicelectronix.com go to subwoofer, get subwoofer amp combo, you should be able to get a decent sub, box, and amp for under 350. whatever you have left you need to spend on a wiring kit, which can also be available on the siteIt depends on how far you want to go with the sound system. If you want to do just subs get an amp, box, subs, amp kit and you should be okay. If you want to go further you can upgrade the head-unit, speakers, get an amp for the speakers and an amp kit.



Good luck!
go to a stereo shop and give them the 350 and ask for a budget system. and they will hook you up with some soso stuff for now they might even have a package deal for you.
Subs amp distributor wires and maybe new alternator
