Product Research

Features

Overview: Pioneer describes the TS-A879 as a wide range speaker (as opposed to a full range speaker), designed to replace the 3½" speaker used by several vehicle manufacturers. Please enter your vehicle information to confirm fit.

Crossovers: A 6 dB/octave, 850 Hz high-pass crossover is integrated in-line with each included 10" length of speaker wire. The output end of the wire has quick slides that plug onto the speaker terminals; the input end of the wire is not terminated. At the widest point the crossovers measure just under ¾" across.

Power: The 100 watt RMS power rating is valid only when using the included crossovers.

Frequency Response: The published frequency response is 52 Hz to 33 kHz (-20 dB), but the -3 dB point on the included high pass crossover is 850 Hz. (The included crossover should always be used, unless the speakers are actively filtered.)

Customer Q&A

5 questions already asked

Q
Do I need to install an amp or anything else, or can I just swap these out with the factory speakers? I have a 25 Jeep Wrangler 4xe with the stock base radio (not the alpine) and looking to get more out of the front speakers.
lanny  Apr 01, 2025

A
These speakers will need an amp to power them to get more audio output. Depending on how much increase you seek, there are some speakers that can improve levels with stock power. I recommend contacting a product advisor by calling 1-800-324-9695 to get a personal recommendation on which will meet your goals

Q
Are there grill covers available for the Pioneer TS-A879?
ricky  Dec 14, 2024

A
Hey Ricky, there are not any grilles available for these speakers. The design of these were always intended to be placed in a location that had a factory grille present so if can sit behind.
red  Dec 14, 2024 (Staff)
Q
if i am connecting these to a 100w rms two channel amp on 4ohms and i already have the high pass filters connected, will they need anything else in between aside from the high pass filters?
bryan  Nov 08, 2024
1 answer
A
The highpass crossover is the only thing besides speaker wire that needs to be installed in between these speakers and an amp.
jason  Nov 08, 2024 (Staff)
Q
Is the bass blocker on the positive side? Normally the negative wire is striped
will  Feb 13, 2024
1 answer
A
Greetings Will. Thank you for your question. In this case the positive wire is black/white. There are two different size terminals on most speakers, the larger of the two being positive. If you look at the back of the speaker as well, the larger terminal also has a black/white wire.
