Alpine Pxe-H650 Help

[knoles]

Hi guys

I'm just wondering if many people have fitted the mentioned sound processors to their cars with success getting good SPL? I have Alpine type x pro splits, type r splits, 2 type r 12" subs in a 4ft cubed box ported at 32hz, MRP-M1000 & F600 amps and although it was quite good sound qual the volume just wasnt there and through pushing all the gains quite high I ended up letting the smoke out of one of my type x tweeters :f*ckyou: That WE I changed to my pioneer DVD headunit and have since had reliable ear splitting good qual sound with out pushing the gear hard, the weakest link is now the car rattles and resonating. Also how much dyna mat do I need to do my car properly? it has a sunroof so not real keen on pulling the roof lining out to do the roof but open to peoples experience.

Did you have premo sound (with sub) pre fitting sound processor or any audio upgrades?

Sound dreading is super necessary in the doors on the back shelf and boot areas

Especially when going for sq

Not exactly sure what your question is but here's a few tips on setting up the Alpine PXE processor. After you have calibrated the system you need to remember to turn the volume up on the processor. The processor will default to a very low value (somewhere around 0-10) after tuning so it needs to be set to max volume (35). If you are using the AUX RCA input for your signal then you will also want to adjust the gain value for the AUX input. Both of these adjustments will have a huge effect on the volume level of your signal.

As for the dynamat you will need approx 18 sheets (2 X Bulk packs) to do your car. This would be enough to cover both inner & outer skins of the 4 doors, parcel shelf, boot and boot lid. If you wanted to do the floor and roof you would likely need an additional 15-18 sheets.

Hi. Yeah my question was in regards to asking if other people have had success with using the std premo sound with the processor to get spl and sql close to an after market HU by itself.

The difference in sound is huge between the two. I adjusted just about every option on the sound processor and had the gain way up on the amps and was getting pretty loud but I suspect it was clipping and it ended up f*****g one of my tweeters. with the aftermarket HU it gets loud without pushing gains over half and volume on HU about half. With the sound processor I had gains on 1 notch down from max and amps where very close to max aswell.

That is why I asked if you had premo sound. DISCONNECT your factory amp on the left hand side of your boot. Then switch ign off and back on. When the ICC see the amp on the canbus it enables high pass filters on the rest of the system. This is why you have lost low end response.

I had the same problem when I put my lc6i in. And now it's just like an aftermarket head unit. I'll swap you my lc6i if ya can't get it sorted

Don't forget to reset the 650 and redo the setup procedure as it will now have full range

Ahhhh yes that's what I was after, makes perfect sense. I might give it another go as I really love the stock look and I quite liked the sound qual from the processor with the imprint etc. More perseverence with tuning this time. (I gave up as soon as my tweeter packed it in, about 2-3 weeks of occasional fiddling)

off on another subject has any one used the latest alpine sound processor pxa-h800 with the rux-c800 controller? how does it compare to the h650 processor?

1 last question. Is the boosted aux input supposed to be as loud as the CD player? my car came with an input but its a fair bit quieter than the cd. How do I tell the difference between boosted and N/A aux input? (this is all refering to the stock icc)

[quadie]

Haven't played with the 800 yet but looks the good

Behind the fuse panel on the drivers side there will be a blue 4 pin

Connector if it has a connector in it its most Lkely for the boosted input.

There also is a 5 pin white plug. This is where the aux audio input plugs in.

Trace it back over to the plug under the tissue box. If there is a black box it's

Boosted. If its straight through its not. Box is usually between the ICC and the steering wheel

Hope that helps
