The third-generation Acura TL, spanning the years 2004–2005, 2006–2007, and 2008, comes equipped with a factory amplifier located in the passenger kick panel. The factory audio system in the Acura TL consists of 8 individual drivers, including the front speakers, the dashboard tweeters, the rear deck speakers, the subwoofer, and lastly, the center channel speaker. When the factory amplifier is working with no issues, the factory audio system sounds rich and full. When your amplifier begins to fail or has failed, the system sounds tinny, and the volume output is very low. If you want to upgrade your sound system or if your factory amplifier has failed, this is a great option to consider. Our plug-and-play amplifier works with the factory radio or with an aftermarket radio if installed with our accessories. The plug-and-play amplifier will work with your factory speakers or aftermarket speakers. This is a five-channel amplifier that will retain all your speakers except for the center dashboard speaker.
This upgrade is plug-and-play so it doesn’t require any new power or ground lines. When installing the amplifier, you don’t have to run any wires to the speakers or to the battery.
These are the amplifier power ratings.
- NEW AMPLIFIER With 2 OHM Speakers: 80 Watts to each speaker + 200 Watts to the subwoofer
- NEW AMPLIFIER With 4 OHM Speakers = 40 Watts to each speaker + 100 Watts to the subwoofer
- FACTORY AMPLIFIER With Factory Speakers: 20 Watts to each speaker + 40 Watts to the subwoofer
Impedance is rated in ohms. Impedance changes in a speaker as it begins to play music, but for the best results, you want speakers that have a resting impedance of 2 ohms. The amplifier will automatically send as much power as it can to each speaker, depending on the impedance of that speaker. There is no switch or setting on the amplifier for changing impedances; it is handled automatically by the electronics inside the amplifier. To take full advantage of this amplifier, we recommend installing 2 ohm speakers for the doors, deck, and subwoofer. We sell 2 ohm JBL, Infinity, and Audison speakers, but there are other brands that also sell 2 ohm speakers. If you also plan to upgrade the subwoofer, the kicker subwoofer we offer is the best choice. There are other subwoofers, but you want one that has a 2 ohm final impedance.
The factory amplifier powers each speaker with roughly 15–40 watts, depending on the speaker; this results in a total power output of 140 watts. This amplifier has a total power output of 500 watts. The factory speakers are all 2 ohms in final impedance, so if your factory speakers are all in good condition, the amp will make them sound great. If some of your speakers are blown and you didn’t notice it before, this amplifier will make you notice it now.
When installing the amplifier, we highly recommend replacing the factory subwoofer at the same time. The factory subwoofer works with this amplifier, but you will have to be careful at higher volumes with heavy bass songs. The extra power can possibly damage your factory subwoofer. As for the factory door speakers, we have found they can handle the extra power as long as the high-pass filter is turned on. The amplifier is shipped pre-configured, so you don’t have to turn any knobs or flip any switches. We ship the amplifier configured based on the selections you make on this page. When shipped, the amplifier will have the proper level set along with the correct high-pass and low-pass filters selected for your application.
This amplifier is packaged with a plug-and-play harness and the accessories you need to install it. The amplifier also comes with a bass knob, so you can control the bass level on the fly. To install this amplifier, you will need to remove the passenger kick panel cover and unbolt the factory amplifier. Then you can proceed to unplug it and connect our plug-and-play amp in its place. The amplifier shares the same connectors as the factory amplifier, so no wiring is necessary. If you plan to install the bass knob that comes with the amplifier, you will have to snake the wire for the bass knob to your chosen location. To mount the amplifier, you can use the supplied screws or self-tapping screws to secure it in the factory amplifier’s location. The new amplifier will fit in the factory location; you will just need to maneuver the wiring harness into the area next to the glove box and then mount the amplifier.
While this amplifier is louder than the factory amplifier, it does not shake the doors off your car or make your window flex from the bass output. This amplifier is a great choice for someone who has a failing amplifier or wants just a little bit more bass from the subwoofer and the door speakers. If you are looking to make your car show stopping loud, you will want to check out our other high-power plug-and-play amplifier. This upgrade will make your car noticeably louder, and you will feel the bass, but you must have realistic expectations.
Please read this disclaimer. The loudness of sound can be subjective from person to person, along with the quality of sound. Almost all of our customers who have bought this amplifier have loved it, but there have been a select few who claimed it was not louder than the factory or that it did not sound better than the factory. We do not accept returns because you don’t like how it sounds or because the amplifier is not as loud as you expected. If you want loud and clear sound, check out some of our higher-end amplifier options.
If, after reading this description, you feel that this package does not have enough power, you can use our amplifier bypass kit to easily install your own amplifier. Please keep in mind that if you are going to power each speaker with more than 125 watts RMS, then we recommend running new speaker wires and suggest you do not use our amplifier bypass.
