    CANBUS and installing new HU

    Thanks. This is the one I ordered that hopefully will work. I guess I will find out when I install it

    CANBUS and installing new HU

    I have a 2013 Fiat 500 Abarth (with Beats factory audio) into which I am planning to install a Clarion NZ503 NAV HU and Alpine amps/speakers. When I talked to the service manager at the local Fiat dealer and told her what I was planning, her response was "fine, but your odometer is going to start blinking after you install the new head unit". Research shows the Fiats are on a Chysler CANBUS system, pins 3 & 4 of the factory harness connector, data signal, puts the system on a internal computer management bus, if one disappears or changes -- blinking odometer. That lead me down a path of doing a"PROXI realignment", to reset the CAN BUS, which, for DIY, requires a modified DLM327 OBD interface and something like MULTIECUSCAN, which is apparently available in EMEA only (the OBD interfaces are available on eBay UK). I haven't yet asked the dealer service manager if they can realign the CAN BUS for me, that may be a better option. My question is -- since I will be using a "AXXESS XSVI-6515-NAV - NAV Interfaces - 2012-UP FIAT 500 RAP Accessory Retention Harness" which is a "CAN" interface, is all this even necessary? It looks like the AXXESS interface provides the required signal on the CAN BUS connections however, since it is going to change from the factory HU, I am thinking it's still going to throw a CAN code which means -- blinking odometer. Any info or advice appreciated.
  3. Just finished the install of an all-Alpine system in my '11 F150, INA-W910 HU, 2 PDX-F4 4 channel amps, Alpine 10" subs and SPR-69 co-ax rear doors, Alpine SPR-60C components in the front. Have the system more or less tuned now and the one thing I can't seem to get past is the mid-range on the SPR-60C's in the front. It just seems edgy and harse at times. Depends on the recording. Yesterday I was listening to Allman Brothers Live At the Fillmore East and the lead guitar on a couple tracks was just brutal as far as mids. Using the G-EQ in the 910 HU, I was able to tone it down some, mostly in the 4-8KHz range using a 2db cut. Don't like doing that though. I am thinking of spending the $130.00 or so for the optional Alpine IMPRINT processor which is advertised as a cure for all SQ woes but before I do that, wanted to see if anybody else has experienced mid to upper mid-range problems and what you did about it. I do want to keep my system all-Alpine if possible. BTW, I am using the factory (Ford) wiring to the door speakers; wondering if that may be a contributing factor.

    running DVC sub on two channels of power amp?

    ok, so I did it this weekend, rewired the two 4 ohm DVC subs to run off each of the four channels of my 4 channel Alpine PDX-F4 amp. That about 100W per coil, 200W per sub into 4 ohms, using the right outputs for one sub, the left outputs for the other. Significant improvement over running the amp bridged into the subs with coils in series at 8 ohms. Very low, almost sub-sonic frequencies now apparent. They hit harder -- not a massive difference in that respect but definite and all good. I need to tune my crossover points to give them a little more in the upper range, around 200 - 250'ish. Door speakers roll off at 100; want to raise that a bit but try doubling up with the subs around 225 (with correct phasing). Overall, it's a keeper. I would almost say, in my novice naiveté, that running a pair of DVC subs, with identical sub/coil input signals, off a 4 channel amp, designed for the impedance of the individual coils and RMS rating, is a Real Good Thing.

    ID the microphone connector in 2011 F150?

    Funny you should mention that, during the week I had time to chew over (with what little brain cpu cycles I had to spare) a way of using the Alpine mic that came with the 910 HU and had sort of fomulated a scheme to do just that (fab something using the existing headliner mic location). The Alpine mic is probabaly a lot more sensitive anyway. I am going to do that and install the PAC steering wheel controls tomorrow. May post a pic if I get time. Do you by any chance happen to know where I can get to the Ford OEM rear view camera wire and possibly splice a RCA connector on it so I can route it into the Alpine 910 HU? THAT is the only total "unknown" I have left on this install project and it's going to keep bugging me until I figure it out. You can take credit for preserving my sanity if you happen to know the answer to that question

    running DVC sub on two channels of power amp?

    Good question -- partially for simplicity and cosmetics (they look great side by side), but mainly because the place I ordered them from gave me a SMOKIN deal if I ordered two. I figured, for that price, I could get creative and make it work. Which is, in fact, the way it is working out Good point about losing a connection. That would probably NOT fry the sub though, my understanding is you can run a DVC sub on one coil, it's just inefficient and sounds bad. The amp would probably shut down in that case as well. Just have to make sure my conections are solid (learned that the hard way -- long story). I'm gonna try it this weekend.

    Brent Davidson has re opened his shop in Central Texas!!

    No, actually I commented because this post came up on a search I did for "Alpine IMPRINT". And I happen to work at Dell in Round Rock. And if there is a person runninfg a shop in Round Rock that is a subject matter expert on mobile audio tuning with regards to Alpine systems, I might want to stop by that persons shop during lunch and talk. You guys are way too paranoid.
  8. When I sourced the subs for the Alpine system in my truck, I bought Alpine SWS1043D DVC subs because they were 4 ohm and in the right RMS range for bridged mode on a Alpine PDX-F4 amp. I bought two of the PDX-F4's because I wanted the same amp for the door speakers and the subs, in bridged mode (200WX2@4ohms). I realize there are better choices for a sub amp, that is another discussion though. The mistake I made when I bought the subs was not knowing that a 200W RMS DVC sub advertised as 4 ohm is actually two 4 ohm voice coils that run in series or parallel. Meaning the load to the amp is actually 2 or 8 ohms. I didn't realize this until 4 months after buying them when I was ready to start the first phase of the install. So, I decided to use them in 8 ohm mode (actually, they measure 6.8 ohms on my meter in series). So, last weekend I finished the main install and powered up, set levels, EQ, etc. -- they sound pretty good. But, predictably, don't hit hard enough. I am more interested in SQ than massive thump but I think the kick drum and picked bass guitar needs to punch through with a little more authority. It's not bad, just could be better. So, what I am thinking about doing is un-bridging the PDX-F4 amp and running each voice coil on a discrete channel for each side. That is: * Left channel, two pairs of outputs, one for each voice coil on the Left sub. * Right channel, two pairs of outputs, one for each voice coil on the Right sub. That way, my amp sees a 4 ohm load on all channels which is what it is designed for in non-bridged mode and the subs are getting the FULL 200W (as opposed to around 140W now because of the higher impedance, lower current, E=IR, etc.). It is the exact same signal to each coil on each sub so no, it isn't going to cause thrashing between the coils. I think they are going to sound a lot better. But, wanted to post about this in case anybody has done this in a similar arrangement and has comments, suggestions, observations, etc. Thanks.

    That is cool, I live just north of Georgetown and work in Round Rock. What is the name of his shop? I just installed an all-Alpine system in my 2011 F150 and would like to get his impression on it and how it can be optimized/tuned for better SQ. Feel free to shoot me a PM.
  10. Is there a site from which one can download firmware updates for the Alpine INA-910 HU? The unit has an ability to update via SD card so, having just installed one of these units, I would like to check wheat the latest firmware is and update it if needed. I would also think that for the NAV functions, there would be map info updates, etc. available. I checked on Alpine's main support site and found no information or mention in the manual for the 910 unit. FYI, they DO have a FTP site (alpine-usa.com) but no anon login allowed

    ID the microphone connector in 2011 F150?

    Yeah, it's the Sirius antenna, routes by glove box, probably up B-pillar to the receiver unit on the roof passenger side. Don't use Sirius with my new system (with HD Radio, why?) but may come in handy some way, somehow. On the microphone, I'll trace the wire from the headliner. Or ID the color code on it, it's probably there on one of the interface connectors in the dash for me to splice into.

    Alpine PDX-F4 shut down

    I found the cause of the problem. It was excessive solder on the ring terminal of the main ground wire to a distribution block causing a poor ground. Apparently only affected the ground wire that branched off to the door speaker amp. I re-did all the wiring using as little solder as possible and both amps fired right up. Live and learn
  13. I just installed an Alpine INA-910 in my 2011 F150. Everything is hooked up except the microphone and the rear view camera. I would like to use the existing microphone that came with the SYNC system originally in the truck (which is now in the corner of my garage with bugs crawling all over it). I am pretty sure this is the connector for the original cabin microphone (the one in the headliner above the drivers seat): This is the tag on the cable: If this is the microphone, can I just cut it and splice on a 1/8 TRS connector for use with the Alpine HU? Also, if anybody can tell me where I can locate the video send for the existing rear view camera (the one that shows in the rear view when the truck is in reverse) that would be much appreciated

    Alpine PDX-F4 shut down

    I just finished the install on my all-Alpine system tonight -- 2 Alpine PDX-F4's, Alpine 910 NAV HU, door speakers are Alpine comps in the front and type-R's in the rear. One of the amps is bridged to run the two subs, the other is running the four door speakers. System ran fine for couple hours while I was buttoning the truck bak up, putting tools away. Set output levels, some basic audio setting on the 910 HU, then took it for a drive to really push it volume wise. SQ was pretty good, then the amp running the 4 door speakers shut down. No power light. The amp running the subs is still on and working fine. Checked voltage to the amp with my meter -- OK. Checked fuses -- OK (visual and checked continuty with my meter). Key off, back on, power light on the amp flashes briefly, then turns off. Wondering if this is the "Alpine Safe Mode" I have heard about. It had plenty of time to cool and wasn't that hot to begin with. I'm thinking it's either a problem with the remote wire or maybe a connector fell off one of the speakers in the doors and now it shuts of because it doesn't see a balanced load (???). Funny, I thought the one driving the subs would be the problem. Any thoughts or suggestions appreciated.
  15. LMAO at the creative use of adjectives in the product description: "built-in vacuum tube amplifier for all the retro-sounding overtones you so desperately desire"
