[QUOTE="Doxquzme, post: 8920962, member: 689267"] Well, the OEM amp has to be getting its signal from somewhere, no? I believe that the front R/L from the HU are full bandwidth signal leads, the rear are heavily filtered and not to be used. The amp likely has factory DSP/EQ built in, which is tuned and designed to work with that amp and the factory speakers, so it is not going to be EQ'd to your aftermarket speakers. What they most likely meant was that it has no usable direct-to-speaker output, as it is a low-level (like RCA type) output, not high-wattage to drive a speaker, to which the following should help address: The LC7i PRO has the following settings that you may have to try to see which one suits the output from the head unit: [B]Load Select:[/B] A slide-switch lets you select one of three input loads to best match the factory system, preventing it from muting the output with no load detected. [LIST] [*][B]20Ω:[/B] Best suited for late model Dodge/Chrysler/Jeep/RAM/Fiat vehicles with a non-amplified OEM sound system. [*][B]60Ω:[/B] Best suited for late model Dodge/Chrysler/Jeep/RAM/Fiat vehicles with an amplified, or "Premium", sound system. [*][B]20kΩ:[/B] Used for most other vehicle applications. [/LIST] This will impact the GTO feature, should you elect to use it as the remote turn-on feature in the LC7i pro. 20kΩ is likely the best one for you. You may want to check with someone like Critchfield or Subaru, but I'm pretty confident that is the case. Good move on the LC7i pro, that'll help for sure. [/QUOTE]
