For a full upgrade the Pioneer DMH-1600NEX is the best car audio head unit, adding a CarPlay and Android Auto touchscreen affordably. The Pioneer TS-F1634R speakers are the best first upgrade, and the Skar RP-1200.1D is the amp to add real bass.
We compare published specifications, safety certifications and thousands of verified owner reviews, and we do not physically test every unit. Read the full process in our review methodology.

A car audio upgrade can mean anything from clearer speakers to a full touchscreen and subwoofer build. The smart path is to fix the weakest link first, then add power and features in order, so each pound spent is one you can hear.
Begin with speakers, since factory units are almost always the limiting factor. A coaxial set like the Pioneer TS-F1634R is a direct swap with an obvious gain. Next, a Bluetooth head unit adds hands-free calls and phone streaming, and a touchscreen model brings CarPlay and Android Auto. Add an amplifier and subwoofer last, once the basics are in place, for the bass that speakers alone cannot deliver.
The head unit is the control centre, offering Bluetooth, USB, and on better models a touchscreen with smartphone mirroring. Speakers convert that signal to sound, and upgrading them is the change most people notice first. Amplifiers add clean power, which matters most for a subwoofer but also lets speakers play louder without distortion. Match the three so the head unit has pre-outs to feed any amp you plan to add.
Two routes exist. A double-DIN touchscreen receiver integrates CarPlay into the dash but needs the right opening and sometimes a kit. A portable CarPlay screen sits on the dash, connects wirelessly, and needs no wiring, which suits cars where a head unit swap is awkward. Choose the integrated unit for a clean look, the portable screen for the least effort.
Do not chase big peak-watt numbers on cheap amps; judge them on RMS ratings instead. Avoid buying a subwoofer without budgeting for the amp, wiring kit, and enclosure it needs. And measure your dash opening and speaker sizes before ordering, since a unit that does not fit is the most common and frustrating error in a first build.
Replacing the factory speakers. Stock speakers are the weakest link, and a 6.5-inch coaxial set like the Pioneer TS-F1634R brings an immediate jump in clarity for little money. After that, a Bluetooth head unit and then an amp with a subwoofer are the natural next steps.
DIN refers to the dash opening height. Single-DIN is the short slot, double-DIN the tall square one that fits touchscreen units like the DMH-1600NEX. Check your dash or look up your car's size before buying, and get a dash kit if the shape needs adapting.
For clearer speakers alone, not always, since a good head unit drives them adequately. For real bass from a subwoofer, yes, a dedicated amp such as the Skar RP-1200.1D is essential. Amps also help speakers play louder without distortion.
Yes. A portable CarPlay screen mounts on the dash and connects wirelessly to your phone, routing audio through FM or Bluetooth. It is the simplest route for cars where swapping the head unit is difficult or expensive.
Wireless is more convenient day to day, while wired is more stable and charges your phone. Budget head units like the DMH-1600NEX use wired CarPlay to keep the price down. If wireless matters, confirm the unit lists it before buying.
An amp, a subwoofer in an enclosure, and a wiring kit with a power cable, ground, and RCA leads. The head unit needs pre-outs or a line-output converter to feed the amp. Budget for the kit and enclosure on top of the amp price.
Often yes, since 6.5-inch coaxials match many OEM openings, but sizes vary. Look up your car's speaker size, and use mounting brackets or adapters where needed. Depth clearance behind the door panel matters as much as the diameter.
Rated wattages can be optimistic on cheaper amps, so focus on RMS figures rather than peak numbers. A budget mono amp is fine for a single entry subwoofer, but for louder builds an established brand with honest RMS ratings is the safer buy.
Buy the Pioneer DMH-1600NEX for a modern touchscreen dash. Start with the Pioneer TS-F1634R speakers if budget is tight, and add the Skar RP-1200.1D amp when you want serious bass from a subwoofer.
