I have been running three amps for awhile in my max using line out converters on my stock HU. The line out converters have gone bad on me a couple of times and I want a new headunit that will accomodate 3 pre outs with decent high voltages and either an SD card or usb input. I have looked at kenwood x590 and jvc G820 at crutchfield. my budget is anywhere between 200-275 dollars.

 

I can do all the installation myself so install shouldnt be a probelm.

 

I went with an Alpine 9856 HU. Tried to use the stock Bose amp for the Rockford Fosgate door speakers I installed...sounds better just wired directly to the HU. I am installing an Inifinity Baselink II with four channel card soon. I will be powering the door speakers from this card.

My HU was $199 from Crutchfield.

 

How does this help?

 

I dont know. I guess I could try to wire my speakers directly and just have a rear pre out go to my sub amp but I really want a usb drive plug in. I see weird companies like power acoustics and pyle having them and insignia but the two best I have found are by JVC and Kenwood. I am leaning towards the kenwood x590. Since it is excelon edition it has high pre out voltages and a 2 year warranty.
