Subwoofer Audio Taper Help
|
New member Username: BleePost Number: 1 Registered: Feb-10 | After searching the forum I couldn't find an answer, so perhaps there is no solution - but here is my question: I'm building a low-budget (I have no money) dual chamber subwoofer box for my F250 with two 6.5" subwoofer speakers (I got free). I plan to drive each speaker by bridging both channels on a two channel 65W existing amp - (per the Rocksford Fosgate 2600X manual). I plan to wire a 6.6mH inductor (per the manual) in series for each speaker to limit the highs. ($12 each!!) Question: I would like to control the volume for both speakers (at the same time) by using a audio taper (potentiometer) mounted on the sub box and wired after the amp. (not pre-amp) I found lots of volume controls for pre amp signal, but not sure if they will work post amp. Can anyone help me select the correct value and ratings if possible? I would like to use a dual channel slide pot if possible. Any vendors or part numbers would also be great. I've attached a rough schematic of my work. I have great high and mids comming from my front and rear speakers (5" punch's & tweets front and rear - with a Rocksford Fosgate crossover box -- old school I know) but I would like a bit more bass. Nothing thumping just a rich sound. Thanks in advance..  |

Also, 6.5's will deliver bass, just not very low freqs. That's not much power to work with either. For me anyway that's a confusing diagram. (Old man). You sure about the ohm loads? |

New member Username: BleePost Number: 2 Registered: Feb-10 | I got the speaker wiring from Crutchfield - I might need to the tone the bass down if it overpowers - perhaps not. I just wont have any control except at the head unit (Bass +/-). http://a248.e.akamai.net/pix.crutchfield.com/ca/learningcenter/car/subwoofer_wir ing/1DVC_2-ohm_2ch.jpg My Amp manual also shows the bridged hook up - (180W per speaker) but not the dual coil speaker wiring along with the 6.6mH inductor wiring. If I have anything wrong - please let me know - I only have the weekends to work on it and I would like to mount the slider before I carpet the box. I hooked up the subs free air without the inductor and got some good bass (but along with a bit of mid range) I wish I had room (and $$) for another amp and some 10" or 12" woofers. Perhaps in another life or if I win the lottery. Right now $$ are tight and this old man has a long commute and a hungry table at dinner time.. |

New member Username: BleePost Number: 3 Registered: Feb-10 | Unfortunatly for me, the LC-1's are for pre-amp (RCA) signals. I'll be wiring my subwoofer from the same amp the drives by mids and tweets so I can't adjust the line level prior to the amp.  |
