I have a 2005 Hyundai XG350L.

I have installed an Alpine CDA-9857 in this car. The car has an Infinity system with a JBL amplifier in the trunk - no sub. Everything worked out great with the exception of one thing - way too loud!!! The problem is that I am sending a powered signal into the amp, which powers again to the speakers. It sounds awesome, but the volume increments from 1 to 2, 2 to 3, etc., are too sensitive. The stereo volume ranges from 0 to 35 and I can't listen past 5. I have read some posts and it appears that I can either adapt from the rca outputs to the amp via hardwiring, or LOC (bi-directional I assume). Or I could just bypass the amp.

My question is which method is perferred? Also, if bypassing the amp, where could I get a wiring diagram for the factory amp.

Any help is greatly appreciated!

Thanks

To bypass the amp all you have to do is find the amplifier and unplug the output plug going to the speakers and do the o'l battery pop test on the speakers to find the proper wires for each speaker. Run the wires back to the HU and tie it up.

** Make sure you test to see which one of the wires is constant first and mark those off before the battery test. **

You can buy a peripherial SVEN4 line out convertor. It will let you hook up RCA's off the deck to speaker wire outputs and its also adjustable levels. I have used this in the past for reasons such as yours and it worked beautifully. This wau if the factory deck ever needs to go back in its a simple plug and play thing.

double-secret reverse-osmosis speaker-cone-induced high-level interference distortion, Its a killer

Thanks for all the input - problem solved! And did it for $12.00! I went to Radio Shack and purchase two speaker cables with phono plugs on each end. I cut the plugs off which gave me 4 total. Hooked each plug up to one channel and plugged it all in. Worked very nicely. No noise, my volume is perfect now, and it solved one other issue... everytime I powered the radio (cranked the car) my speakers would pop. This was obviously due to the amp turning on with an already "hot" signal. Now that's gone.

I appreciate all the advice. The SVEN4 was the route I was going to take, and still will if I encounter any problems with this. If anyone knows of potential issues I may face with this solution please let me know.

Thanks.
