i've had this subwoofer mod for quite some time (preamp+eq) but for some reason after about 25-30 min, the enhancement stops. the only way to get it back it to restart the car. anyone else experiencing this anomaly?
ive made the V1 edition , i can sware i have everything connected right... but when i test it using a function generator and oscilloscope i get a real fucked up output ... doesnt seem to be working right ...
ive tried to make it three times with 3 different capacitors, Bipolar, tantalum, ceramic and MKT aswell as tried three different 741's and they all do the same thing on my testing ... whats going on!!
does it have anything to do with the fact that im using a line level as the input and the preamp works off the bose amplified output ?
Well I don't give a crap about the fancy features like adjustable eq and such....just want a boost in factory bass that it controlled by stock HU without taking up any trunk space. Gimme a shout if you end up making another of the simple versions.
