You might find some inspiration about PXA modding over here. It's all in German but mainly pics anyway...

Very nice. I'll have to look into it. All I'm really concerned about with the H700 is possibly improving the main stereo channels (3 and 4 I believe). The others are fine as is. I'm doing a lot of mods to the car itself so I'm not doing much with the sound system right now. In fact, it's completely removed from the car.

From the looks of it, that guy improved on the following items:

• Crystal PCM IC: swapt for a better version (same datasheet, S/N and dynamic range bettered by about 5-6db)
• Better opamps
• additional caps for PS filtering
• PS direct soldered to PCB

I might try to contact him, asking about details and results.

Hey guys, not to sound like a n00b but I'm having a hard time figruing out how to wire my H701 with my Alpine CDA9883 deck. The problem is with the set of wires for the power to the H701.

I understand that I just splice/connect my h701 remote out to my external amp. Not a problem. I also understand that the black groudn wire can be ground to my cap in the trunk of my Jeep liberty where there two subs are currently installed. My problem is the power cable.

It has two ends. (why?)
And what is with the odd looking connection at the tip, where does that go?
So my question is basically this:

Am I better off installing the H701 in the trunk where my two amps (mono for sub, 4 channel for highs) and my cap are all installed, and running my power and ground to the cap like my amps are?

OR

Installing it under my passenger seat? And if I install it here, where do I place the power cable? Can it be run from the car battery? From the Cap in the back? I'm not sure where my headunit (CDA9883) is powered from because I had that professionally installed. And how do I connect the power cable when it has that odd shaped ending?

Any advice is appreciated. Thank you.

It's probably best to mount it by the amps that way you can use very short RCA cables from it to each amp.

Just cut both of the funny connectors off the power wire and feed it constant power.

That's what I figured. Beautiful, thanks guys.

One more question boys -

Where do I plug the Digital Toslink from the H701 into? I have a CDA 9883 deck and I don't see any digital outputs. Just four analog for my four channel amp and two more for my subs.

You know what, a better question I should ask is -

What can the CDA-9883 do with the H701? Just control the volume? I was under the impression that I could tweak the EQ and Cross over with it? I have my Ai-Net control wire going to the H701, but not sure what I should connect as far as sound goes?

Looking at the specs of the 9883 it does not have the digital output. Usually it's just the DVD capable HU's that have the optical out and that's usually for the 5.1 channel data. I haven't got a long enough optical cable yet so I'm just letting the music signal use the AInet cable. The sound quality is very good.

I think a HU would have to have the "Processor Control" ability to control the H701 EQ, x-over, etc.... The 9883 doesn't seem to have that. It's not that big a deal though. It would be a royal pain to control it with the small display screen. The RUX controller is way better, plus once it's set you really don't access the controller very often. Maybe just to change the preset button.

From what I can tell, your 9883 becomes the master volume control which is good. That means it controls the output level of the DAC's in the H701 right before it hits the amps. This keeps the noise floor very low. Also the AInet allows you to easily hook up other devices like sat radio and control it at the HU. So it's really not that bad.

Thanks. The only reason I was confused was because of the instruction booklet with the CDA-9883. It has Aux, and a Dig-Aux source, and says it can connect to the H701. So I think great, I'll go pick up the H701. Also, under the 9883 It has a switch for EQ/Div - Norm, so I'm not exactly what that is for. I was just upset that the manual said that you can control the H701 from the deck, only to find out yeah you can control the VOLUME, but nothing else. Would have been nice if they had stated that in there before

Anyway, I'm pretty sure I'll have the Alpine IVA-D310 tomorrow anyway. Worst case I'll just pick one up myself. But as far as the Ai-net items, I knew how they worked. I have Sirius, and an ipod adapter in there so that currently takes up that slot.

So the final question, The Ai-Net wire can carry sound as well as a controller signal?
