I have a '98 4runner with the factory radio/cassette/cd with 6 speakers and a external amp thats mounted just below the radio. I'm installing a 2 chanel amp to drive a mtx truck box with 2 10" woofers,2 mid range, and 2 tweeters. Since my stereo does'nt have rca outputs,I'm using a line output converter to give me my low level rca outputs. I tied in to the speaker wires on the output side of the factory amp , but I don't have any audio on the right side. I'm using the black / yellow wires for the left and the red / white wires for the right. I've checked all the connections, the rca cables, etc. Could the right channel of the amp I'm adding be out, or the converter be faulty?

Try switching the RCA output of the line level converter around and if the RIGHT channel plays and the LEFT does not then you know it's the wiring and not the amp. Do you have the double DIN or the single DIN player in the truck ?

thanks for your reply jeff (at velocitymotorsport) . I think I have the double DIN player. This is probably a real lame question but how do I tell the difference between a double or a single DIN player?

A single DIN unit is the standard sized players ( about 2.5 " high and a double DIN player is twice that size 5 ".

I tried swaping the RCA cords and yes the right side of the MTX speaker box works instead of the left. But I've triple checked my wire connections. I'm wondering if the line output converter that I got from crutchfields has a dead right side. I've checked the continuity everywhere but "thru" the line output converter.

Did you check for continuity in the RCA wire ? You could have a bad set of RCA's ?
