What Do You Need in an Amp?
Everycar sound systemhas an amplifier of some sort, but most are built into head units.
In general, you need one channel for each speaker that you want to amplify.
If youre adding asubwooferto an existing system, then a single channel amplifier will get the job done.
Units that have two, four, or six channels are more versatile.
By providing a raw, un-amplified signal to the amp, youll end up with the clearest sound possible.
Most factory head units and many aftermarket units dont have preamp outputs.
With that in mind, taking some measurements before you buy an amp can simplify matters.
You also need to verify your car’s alternator can handle the increased power draw.
