Hey guys, I am trying to add an amp withtwo subs. I already know where I am hooking everything up as it should be easy with the battery right there in the back seat. The question I have is about the in-line convertor that will be needed to switch the wire from the original rear sub to an RCA type to run to the amplifier.
Most In-Line Convertors are atleast two channel, and since there is only one subwoofer (the orginal) that I am going to be running the convertor from there would only be one RCA jack to plug in- what should be done to get it to work properly. Should I split the wire and make it two each (pos) and (neg) and run it to the convertor so that it is set up stereo or (2 channel) so both RCA jacks can be plugged into the amp?
Please leave advice if you know anything about doing this and maybe a brief description of how you did it.
You might want to move this down to the Technical Discussion forum, Audio/Security. Lots of aftermarket sound work down there.........and do it right, or you'll open an electrical and security can of worms that is hard to close again.
I have the same car with 2 subs and a amp running off the stock HU through a Hi-Lo Converter but I had a shop do the install so I'm not sure.
One piece of advice I would say though is remove the Bose woofer from the rear deck. It will allow more air to flow into the cabin so you get more bass. My box is wedged under there but having it removed helped out I'm sure.
BTW, what are you running? I'm only running 500rms and because the trunk is a nice size and sealed tightly it gets loud inside.
If the subwoofer is only one channel you should only be setting up a single channel for the new subs. Heed the posting Sub's advice and be careful with your installation as these cars are sensitive to low voltage.
I am only running 300 rms 2 -12's in a sealed box. I ran a PAC Convertor from the (1) positve and (1) negative wire from the original sub. to the (2) positive and (2) negative wires on the convertor. I also removed the old sub so air can flow through the hole.
I have one question tho, has anyone had their stereo turn up and down spuratically by it self? It's like their is something causing it to go from let's say volume of 2 to around 10 and back. I have everything hooked up right. I turned off the automatic volume control and think that fixed it but not for sure. Please let me know what this could be.
Set as Front Seat with the level set all the way up...I tried using the rear speakers but they just ruin the front stage IMO so no need for them, gets plenty loud even though my driver door speaker doesn't work
Yeah, it was definately the auto volume control causing the spuratic volume changing. Doesn't do it when it is off.
Used a PAS SIN-35 line out converotr and hooked it up so i was using both channels from only the single channel sub. 300 RMS sub amp and two 12" subs in a sealed box and it sounds awsome now. Cost me about $40 for the amp wiring kit and the PAC convertor. I already had the amp and subs. Nice cheap way to get some bass. This stereo rocks now!
