I'm assuming you don't have the pleasure of driving the Subaru BRZ. The standard Fujitsu FA601US equipped on all USA cars does not have RCA outputs like the FR-S does.

I will be using an Alpine PDX-F4 to power them as soon as my LOC gets in. My amp is already wired!

I am hoping so, but I keep having this itch to want to maintain a 3 way setup. I love how present the stage on the OEM speakers are. Do you think that there is a point there to maintain a 3 way setup when upgrading speakers if you don't want to loose that aspect of your sounds response?

No such pleasure. Mine happens to have 3 sets of preouts and in preparation for a hiccup down the line I have an x940bt sitting on the shelf. Now I understand your reference to the LOC...it sucks but I understand nonetheless.

A disclaimer: I'm still waiting on my BRZ so I haven't been able to spend much time in one listening. However, I would think that the fact that the mid and high are mounted at the corners of the dash/windshield is what really brings the stage up front. With a larger tweeter, you may be able to achieve decent staging with a two-way setup. Not sure where the crossover point is on your particular components, or how low your tweeters can play without failing.

With most three-way systems, the mid affects the staging more than anything, as that is the range of sound our ears/brains are most effective at locating, and I would expect it to be the same with the factory setup.

Quick question for you guys, if I installed components can I just remove the oem amp and replace it with an after market one? Would that work?

Thanks! Didn't feel like doing extra work and run wires from the front to the back.

Sorry, I misunderstood. You can replace the oem amp but it isn't plug-n-play. You'll need to run the wires.

So to clarify on this, you can grab your front speaker signals from the harness that plugs into the rear OEM amplifier.

Look up the wiring manual on the forum to understand which wires are what. The connector is a Metra 70-1761 that you can get from ama zon.

Just to be clear, The front door speakers are powered by the stock amplifier right. The rest of the speakers in the car, the two speakers and tweeters on the dash and the rear speakers are all being powered by the head unit?. Right now i am running jbl p66s speakers in the doors and infinity reference speakers on the dash. The jbl's are 2ohms and have 55 watt rms. Does the stock amplifier have enough juice to power the jbl speakers?

I am thinking of getting the alpine power pack to boost the head unit's power output. the alpine power pack is good in that it can be tucked away behind the head unit, a much cleaner install.

The stock amp probably has enough power for your JBLs at low to normal listening levels. However, like the OEM speakers if you turn up the volume there will be distortion and this will be a strain on the JBLs.

vignesh · 04-14-2013, 12:58 PM

So the amps just power the door speakers right?

Yes. Kind of unfortunate.
