I recently purchased a Sanyo ECD-T1545 Head Unit. It has CD/CDR/CDRW/MP3 capabilities. Sirius Satellite Radio Ready, 2 Pre-outs, and Subwoofer Output (nonfading), and many other cool options. I have two questions.

1. When I was installing it, I noticed that the subwoofer preout has only one plug, instead of two like the other Preouts. I bypassed this using an RF Modulator and hooked it up with my front speakers on the front pre out, the sub on the rear output, and the rear speakers on the rf modulator. I am just curious is there anything I can do to use this subwoofer output. It says on the website that it is "non fading" does this mean that it is just one out put. I really want to get rid of having this RF Modulator in my car, and I was curious if anyone knew of anything I can do.

2. When I listen to an MP3 disc, the head unit, doesn't play some songs. It will play the first 100 or so, but then can't seem to play the last songs. I was thinking maybe it is my CD Burner, or maybe it is something wrong in the head unit. It beats me! Anyone got any ideas?

Thanks in advance for any input

1. The single subwoofer pre-out is just a mono signal. hook it up the the left channel (double check the manual to make sure this is correct) on the subwoofer amp and make sure the switch is set to mono and not stereo. the single output from the headunit most likely just combines the left and right signals into one, instead of having the amp do it. i think nonfading means that you cant control the subwoofer volume from the headunit but i could be wrong there. Setting it up like this will let you use the front outputs for front, rear for rear, and sub for sub, thus eliminating the "rf modulalator" (i think you mean "line level converter" or something similar)

2. read the headunit manual and see how it needs the file naming done on the disc. it may not be able to read more than 100 files in a folder, therefor make more folders and split it up into categories or playlists.

hope this helps

Non fading output means that when only your left or right channel is playing. or only your front or rear is playing, the sub won't change at all..

thanks....I'm gonna try it out, I did try to use a y-adapter on the line to make it able to accept the left and right of an RCA cable, but that didn't seem to work.....why wouldn't that have worked, or should it of worked?

It should work, but you don't need to have it if you're only using one channel for your subs.

right so if I hook it up using the y-adapter then I switch it over to a mono signal, instead of stereo I should be all set......so should I just forget about the y-adapter and use a single cable going from the sub output on the head unit to one of the sub inputs on the amp, and switch it over to mono???

Yep, that would be the way to do it. If you don't have the manual to check which channel to use just try one. If the subs don't start working plug it into the other channel.
