What really fits in the dash of a 2005+ Frontier plus some general speaker info
Hey All,
I just finished installing my Pioneer Ts-T110s - was very easy with nice results.
1st off thanks to Boomer for sharing his Ts-T110 install.
I searched and read everything on the topic of Frontier dash speakers/tweeters. I came away with some direction but not much detailed information. i.e. what exactly fits, even Crutchfield had no clue.
I decided I would share my experience and hopefully help some out down the line. This is for my 2006 CC, yours may or may not be different.
So, what fits?
Once I had my stock tweeters out this one had me puzzled as to why there was no hard numbers on this. Seemed pretty clear cut as to what could fit. There is a 2.5" dia cut out with 4 mounting holes on a 3.1" dia bolt circle. Unobstructed depth is about 1 1/4". Space between the stock bezel and mounting surface is about 1/2". Based on this info alone you could go buy a set of tweeters and by 99% sure they would fit.
I had originally planned to install my Ts-T110s with washers, the same way Boomer did. But with the information above I thought it would be pretty simple to make a drop in adapter plate (it is) and more securely hold the tweeter in. Below is a template (pdf at bottom) for a ~3x3" plate with the 3.1" dia bolt circle and a 2" hole (2" is what I needed for my Ts-T110s - this can be changed for your tweeter size up to ~2.5"). Print the template and glue it to your substrate of choice ( I used 0.06" thk plastic sheet) and cut out. Beforehand, confirm your print is: to scale and/or not compressed in one direction (ie circle is an oval) - adjust as needed.
Some general info on Frontier speakers CrewCab specific
nonRF system
Front 6x9 and tweeter are 2 and 4ohm respectively wired in parrallel - head unit sees 1.33ohms using stock wiring!
Stock tweeter has a 3.3 uF cap which corresponds to a 12kHz 6dB crossover
Stock 6x9s DO NOT have a crossover. Unless there is one buried, but I doubt it.
Rears are 6.5" - 2ohm
RF system (guys w/ RF please correct if I got anything wrong - Thanks for your input Steve)
Front 6x9 and tweeter are 4ohm and are wired directly to the amp (ie separate leads/channels)
Tweeter is bigger than in nonRF systems - more of a midrange. Any high pass filtering is done in the amp.
6x9 is driven more as a woofer, again filtering done in the amp.
Rears are 6.5" with a separate tweeter and are wired in parallel same as the fronts in a nonRF system. Tweeter has high pass cap integrated as well. Not sure of value.
Tweeter replacement STEPS
1) Remove grille - a credit card works well
2) Remove stock tweeter
3) Make adapter
4) Mount tweeter on adapter
5) I hacked the stock connector off and used it as a connector on my new speakers. USE LOW HEAT TO SOLDER AND CHECK PINS BEFORE ASSY.
6) Plug in to harness
7) Install into dash - oh yeah you will need to get some more speed or plate nuts.
8) DONE!
