RCA or head unit trouble.
|
New member Username: ShagsPost Number: 1 Registered: Apr-04 | I am currently trying to run a JBL 300.1 amp and a rockford 200S to run 3 10" subs. The JBL will be pushing two of the subs and the rockford one bridged. I was wondering about the RCA cable. My head unit, Blaupunkt BPV 755 only has one set of RCA jacks. I already got some Y spliters (one female going to 2 males) but I was wondering if putting these in wil decress preformance of my current two 10"'s. Currently only running the JBL 300.1 with 2 10" at 4 ohms. Also I found something odd, while my subs are playing if i unplug the left channel, nothing happends to the sound, if I unplug my right channel the subs stop playing enterly. Is this right? I think there is something wrong with my head unit. Any input would be appreciated. Shags. |

New member Username: ShagsPost Number: 3 Registered: Apr-04 | it came loose off the head unit, sorry guys. But splitting it made the amps loose there quality, EI not as loud or as crisp bass. The head unit only pushes out 2V out of the line out. Maby 1V per amp was not good enuf. |
