Will my car handle a standard sub install.?

Question

I have a ford fiesta 1.25, it has a 12v battery. I just want a nice basic install around 12'' sub not to big - but big enough. I generally dont have a clue about all the technical issues like ohms and rms and stuff like that!!! but have a basic knowledge of electronics. And alot of you guys sound like real experts that i need a bit of advice from!. I am going to replace the door speakers and just asking if these would run easily off a headunit (kenwood probaly) or would they need to be connected to the amp. Also would 5'' component speakers be ok on their own or would i need additional speakers ie 6x9s on the rear shelf. Cheers guys!. ps i know this question is lacking alot of technical specifications like what size amp amp and what type of head unit but the i havent got that yet so just consider everything to be avarage i.e not to big not to small.

Answer 1

For just one amplifier the car could support the supplying of power for the audio system. You can connect the front speaker to the kenwood head unit and use a 2 ch amplifier to power the subs, is a very simple system. If you feel you need more power to the front speaker or the subs silence the speakers you could get a 4 channel amplifier to power both subs and speakers, just make sure the amplifiers doesn't not supply more power to the speakers than they can handle, always look for the rms values in power rating, @ 2 ohms and 4 ohms depending on the connection you want to do.
If the component speakers has highs and mid then don't, but if only high you should get a 6 x 9 which they play very nice and can support more bass than 5".

Answer 2

I'd suggest purchasing a 4-channel amp and using 2 channels to run your front speakers, while bridging the other two for a subwoofer. Replacing your front speakers and amplifying them will make a big difference in your sound quality, but there's no need to upgrade the rear speakers if you're also adding a sub. Even a budget 4-ohm single voice coil sub will give you a nice low end for a balanced, powerful sound.
