For quality sound and avoidance of technical mishaps, you need an amplifier installed in your car. The size and type of car you own will help you settle on a specific amplifier and where to mount it. A majority of car owners mostly fit the amplifiers the car's luggage compartment. But if you are driving a model like an SUV, this means you will have to reconsider the mounting due to space limitation.
Installing a DIY Car Amplifier
Do I Need an Amp Fuse for My Car and What Size?
This will involve disassembling your dashboard and running multiple wires from the head of your vehicle to the sub in the trunk or under your front seat. You may need to purchase additional speaker wire or RCA cables outside of your wiring kit. Consult your manual before ripping any fabric up. If you want to wire an amp to a sub and head unit, start by turning your vehicle off and popping the hood. Then, poke a hole in the rubber next to your firewall and feed the power cable through the hole with a wire coat hanger. Finally, hide the power cable under the floor mats and run it along the floor to the back of the vehicle so you can connect it to the amp.
Car Amp Install.
Most cars come with very basic audio systems that only include a head unit and four speakers, so upgrading beyond that is more complicated than simply replacing old components with new ones. If your car didn't come from the factory with an amplifier, and it probably didn't, that means you need to wire it into power and ground, and that means you need some type of amplifier fuse. If you aren't careful when running a power wire for your new amp, and it shorts out, and it isn't fused, you could be looking at significant damage. In a worst-case scenario, a shorted out amp power wire could even cause a fire. Even if you are careful, simply driving around on the smoothest of roads causes everything in your car to bump and jostle around a whole lot.
Installing a subwoofer in your car yourself feels great! Better to plan well or stop and pick back up the next day. A good estimate is perhaps hours or more for adding a subwoofer to an aftermarket stereo and 4. The right tools make all the difference!
