whitey Posted February 26, 2010 Share Posted February 26, 2010 Hello, I am just about to purchase a Infinity REF5350a amp but have a question: On the back of my Pioneer AVH-P4100DVD there are preouts for the front, rear and subwoofer. The subwoofer outputs have SWL and SWR: On the amp there is a sub1 and sub2 input but not L or R and the diagram only shows one rca cable being inputted: Do I only need to connect to one of the subwoofer outputs on the headunit or do I need to buy a rca cable that has two male connectors one end and one male the other? Also does anyone know of an easy route to get from the inside of the car to the battery compartment for the amp power cable? Ideally through the front bulkhead? I will be removing the headunit if this helps. Cheers Quote Link to comment Share on other sites More sharing options...
yokomo Posted February 26, 2010 Share Posted February 26, 2010 well that amp is a 5 channel amp so youl need to connect all 3 sets of rca to amp. the sub1 sub 2 doesnt really matter thers just 2 because rcas tend to come as pairs. amp power is really easy , theres a guide somewhere in the guides section but basically you just take the cover off the battery area under the bonnet and youl see a big ole grommit. pop a little hole in with a sharp knife, feed the cable through and youl be in the passnger foot well .

whitey Posted February 26, 2010 Author Share Posted February 26, 2010 Thanks, So what you're saying is that I only need to connect one of the RCA's? Quote Link to comment Share on other sites More sharing options...
yokomo Posted February 26, 2010 Share Posted February 26, 2010 yes you could just use one, id guess sub 1 but as thers only 2 choices trial and error wont take long will it . are you not going to use the rest of the amps channels then ?

whitey Posted February 27, 2010 Author Share Posted February 27, 2010 Thanks, Yes, the other channels will be used, 2 for the front, 2 for the rear and 1 for the subwoofer. It was just the subwoofer channel I had the problem with, I didn't understand why there was two outputs on the headunit and only one on the amp.

yokomo Posted February 27, 2010 Share Posted February 27, 2010 yeah some Headunit s have apair some dont or it could be thats its a front centre channel and you head unit has 5.1 output for dvds. either way not a problem really just run the 3 sets of rcas and hook them up the amp will only use the channels it needs or if you have a single lead from the head unit i sugges you test whihc one is the sub out put before putting the dash back. good luck and post up some pics as you should have a nice system started there.
