i just ordered it tonight, so hopefully it'll work well...

it utilizes the existing amplifier to power the speakers, but the only problem is that you have to have a headunit with RCA pre-amps for front and rear speakers (for using an external amp instead of the local 50ish/per speakerwatts in the headunit)

whenever it comes, i'll install and take pix and tell how well it works/if at all...

this should be made a sticky for future reference, cuz i had a HELLUVA time tryin to find this part!!!!!
