subwoofer

[BenChan]

okay .. im noob with the mazda3. just wondering if there is a sub in and out on the stock mazda3 deck. AND if i add a subwoofer in .. 10" OR 12" will i need to change my speakers too?? because i dont really want to change the speakers when i add the sub in.

This should be in the I.C.E. (car audio) Section but I'll give my input until it gets moved.

There isn't a stock in/out on the deck for a sub. You would have to add a LOC (line out converter) to take your audio from the deck and convert it into an RCA signal. Then you would run that signal to an AMP and then you your sub.

You'll need a bunch of things to make the sub work and it can get pricey. Just giving you a heads up if you didn't know.

No you don't have to change your speakers but you will probably want to once you get your sub in. The sound quality of the stock speakers are crap.

how i did it was. i am currently running my subs through my rear speakers. as what CWP_sedan said you need the Line out convertor which you can get at canadian tire for like 30 bucks for a basic one. then what i did for ground is used the spare tire jack stand which worked well, and the cigarette lighter fuse for my REM wire, and obviously the power wire. it works well, granted not as well as if you were to put an aftermarket deck but it still makes it sound half decent. and you dont have to change the speakers, i havent but im looking to do it soon. and with the stock deck im running 4 subs and a 1200 W american legacy amp. soo hope that helps you out. if you need help on how to do it let me know as ive done it a few times. good luck
