[FR-S2GT86]

So to start off, I've taken good care of my collection of mobile electronics over the many years since I started this hobby (and for a few years back in the day, this profession) and I decided to begin a new build for this '15 FR-S that will include two "veteran stars" from the old days, along with some new "supporting actors" from today.

In the dash on top, and in the leading role, I present my 18 year-old Pioneer Premier DEH-P940MP in 3-way network mode, and underneath that, in one of the spporting roles, my new Alpine CDE-172BT to add a host of modern features to the setup via the Pioneer's auxilliary inputs.

In the trunk, and co-star of this show, I have my 20 year-old, first generation Orion HCCA 12-inch, dual 2-ohm subwoofer wired in parallel, powered by another one of the new cast members in a supporting role, my new Cerwin Vega Stealth Bomber B51 mono-block amplifier.

To round out the rest of the cast is my new Stealth Bomber B54, 4-channel and B52, 2-channel amplifiers which are powering all Dayton Audio brand 1-inch tweeters, 3.5-inch midrange drivers, and 6.5-inch woofers all in the front factory locations.

I had to fire the factory rear speakers as they kept showing up to the set hung-over from the night before.

This setup is technically a 4-way network system with the high RCA outputs of the Pioneer head unit feeding the first two channels of the B54 at 80 watts RMS per channel at 4 ohms for the tweeters, the low RCA outputs feeding the B51 at 500 watts mono into a 1-ohm load for the sub, and the mid RCA outputs being split and feeding the second set of channels of the B54 for the 3.5-inch midrange drivers at 80 watts RMS per channel at 4 ohms, and the two channels of the B52 at 150 watts per channel into 4 ohms for the 6.5-inch door mid-bass drivers.

The combination of the built-in crossovers and time alignment of the Pioneer head unit, along with the on-board crossovers and sub-sonic filter of the Stealth Bomber amps makes this entire system so simple to adjust once you get all the gain and level settings correct. So far, except for some vibrations in the doors and rear deck, everything is sounding great.

The small size, light weight and features of these Cerwin Vega Stealth Bomber amplifiers along with the 250mV to 10V signal input sensitivity are what sold me on these new amps. I highly recommend them if space is a concern. The Pioneer head unit can put out a clean 6.5-volt signal on the RCA outputs which was very high for it's day, and still higher than most head units today which was an important factor for choosing amplification and it took me weeks to sift through all the specifications of several brands of amplifiers for me to finally choose the ones I did.

I'm still in the process of building everything which is the reason for the messy wiring, and right now the Orion sub is in a cheap Walmart enclosure until my custom enclosure is finished, but I promise to update this thread when I get everything in the trunk a bit more organized. Until then, thanks for taking the time to read this. If anybody has any questions about this build or suggestions, just let me know.
