Ok - so I've finally made the HU swap in my 2011 P4x!
Pioneer AVH-W4400NEX with a Maestro RR for Steering Wheel control and gauges. I used a PAC OEM-1 LOC to take the speaker level outs, get it to line level, and out to the factory harness. I based most of my install from https://www.thenewx.org/forum/15-how...up-camera.html
but man... there really is info lacking as far as the Maestro RR goes, especially wiring in the SW controls. I'll follow up more on that on a future post hopefully.
This post though is about integrating an aftermarket headunit with the Rockford system. After installation, I was underwhelmed by the sound - the sub wasn't kicking as hard and no matter how I tuned it, it just felt worse than the OEM HU. Using any of the features of the HU such as time alignment ect made it worse. After further investigation and reading up, it appears that the Sub is being fed from all 8 speaker lines and crossed over at the amp. So any panning, crossovers, time alignment at the HU was helping the door speakers but effecting the signal to the sub. Kind of a bummer.
So here are my thoughts/options. Let me know if going down the right path or erroneous in any way.
a)Replace the rest of the RF system with a new sub/amp and either add a component amp or wire new speakers directly to HU
Probably the best quality sound option. I know most people will say just do this, but I really don't want eat any storage space with a box or make a custom box for under the seat though. This is also the most expensive option
b)Add a second component amp and swap door speakers. Run RCA out of HU for those Front and Back channels, and keep the LOC in line to drive the factory RF Sub/Amp.
This seems to make sense right? Can I output both to the RCA and Speaker level outputs form my HU? I guess any EQ/crossovers would still effect the sub huh? This would be a little cheaper of an investment.
c)Swap and/or wire new speakers directly to HU using the speaker outs, wire in the factory RF amp with the Metra 70-7551 Amplifier Integration Harness to the Sub out on my HU.
This seems to be the most feasible way to get the best sound for $$$ and keep the stock sub, right? I could then EQ and crossover my F/B, and not effect the signal to the sub. Am I loosing much ot only drive the RF amp with two channels of RCAs? Also- My HU has 4V Pres on it, is that ok to drive the RF Amp? Or is this setup the one that causes the POP when switching sources? If not, should I have skipped the LOC altogether and just used this Metra harness? Also - would the Pioneer be find to drive the stock speakers directly If I hard wired them?
d)Replace F/B speakers and wire to speaker outs on HU, Replace OEM RF amp, hardwire RF sub, and connect to Sub out with RCAs
Is this even possible?
Would love to know anyone's thoughts/insights on this and how to get the best sound out of the RF system after swapping the HU.
