Have a alpine iva-w505 with a mono amp for a sub and another amp for the speakers. I bought alpine pxa-h100 and ktx-h100. I hooked it up per the instructions for a front/rear/sub connection. I switched the switch on the bottom of the radio from norm to div/eq. I get no sound coming out of the speakers. Any ideas

Its the problem with amplifier

the default pin on all units is 0000, your welcome :)

Check Sub Setting, could be turned of.

There is not much that can be done to a broken screen pad but to replace the whole unit . Please get help from the service dealership or post yourr problem to the link: Alpine official site.

yes you can as long you other amps has output aux ports i have 3 fusion hooked together so its no problem

depending on how many channels the amp is, you may not be able to hook everything up to it.

usually you have a separate amp for subs. 4 channel amp for the speakers in the car, and a mono amp for the subs.

To hook them all up to the same amp you would need an amp with 5 channels. It wouldn't work out right.

If you have a mono amp its only for subs.

If you have a 2 channel you can either hook it up to the rear speakers or bridge them to mono to run the subs.


you need a channel per speaker basically.

Alpine does not have any updates to this 4-5 year old map at this time per Alpine tech support. It is the same out of date mapping as the BT200 - when available, it may be supplied for free... or at a charge from there website - support. Also, having problems with your iPhone 3G syncing your address book. Alpine is having me send in my NVE-P1 and they are replacing the hardware inside so that it will now sync. Also, iPod Touch, and iPhones need at least version 3.0 in order to display video to the W505 unit.

bose speakers are EXTREAMLY sensitive to the current applied to them. meaning if the wrong amount or too much is applied they will not work or will blow out completely.. was the other cdplayer stock? if so id go to radio shack and get a cheap speaker and hook it up just to see if that would work

The way the EQ is hooked up is correct.

You set the factory radio to a set level, then use the volume on the EQ for everyday adjustments.

I believe your problem lies in the amplification.
Your BOSE amplifier was made to run a 4 channel 8ohm stero load.
Low powered - high in sound quality.

You have swapped the factory 8 ohm speakers (15W) for 4 ohm power hungry ones.
Now the amplifier is working harder to produce the same output.

You would be best served eliminating the factory amplifier and getting 1 good 4 or 5 channel amp to power your speakers.

a 4 channel amplifier could be used stereo (left and right) on channels 1 and 2, (2ohm stereo load)
and bridge channels 3 and 4 for your subwoofer.

For a true surround sound - a 5 channel amplifier could run each speaker individually, and the 5th channel is reserved for the subwoofer.

a small dedicated 75wx4 channel amplifier with built in crossover, and level gain controls - would blow your socks off. It is 200x better than the factory 12Watt amplifier. Your ears will love you for it :D

If you need more help - just let me know.

You will only need to connect the door speakers to the MRA-F350. In short, the connections will be as follows:

Deck---->MRA-F350 amp---->Door speakers
...................................\---->Sub amp---->Sub(s)

Just make sure you use the optical digital output of the deck to connect to the optical digital input of the MRA-F350 amp, not the RCA preamp connections.
