Hi.
I got an Alpine CDE-121E in my satria.
Recently installed an amplifier and during this I found out that this HU just have 1 pair of RCA preout, and that's for subwoofer only.
So we just go ahead and split the output, feed it to amp.

I doesn't sound good. have tuned the output using the sound control, sounded ok but not SQ ok.

Will a preamp fix this?
Otherwise I'm changing HU.

Any pointers from ICE masters?
