Is it possible to bypass/trick a low pass filter?


Recommended Posts

I had this amp on my old sub setup, it did OK for subs but not enough power for me

I don't see why this wouldn't work as a good mids amp If I was willing to give up my fader ( I don't plan on having dolby digital in my truck).

The only problem is that it has a "Built-In Crossover (80Hz Low-Pass Filter)" It states this is "very smart" but is SMD smart enough to figure out a bypass so I could push my components with it?

Thanks for the info.

***EDIT*** I have another question, not sure if it deserves it's own thread though. For the wiring going to the subwoofers themselves, should I be brazing/soldering the ends of those going into the terminals of the speakers and amps, or just leave it as loose stranded wire. I will be using 8 gauge wire from amp to speakers.

Move the crossover switch to the off position on the amp.

My head just exploded... That is the most insanely ingenious way ive ever seen to bypass a crossover......

Lol.... Actually, i was thinking the same thing just reading the title before i ever clicked on it.

I know that, I made myself look like an idiot there. I mean to ask, does that make it a full-range amp as in bypass it completely? I don't know if built-in means automatic or if that switch is a bypass to the "built-in" crossover. If I used it for some mids, would I just put an equalizer or something on the outputs?

I don't know much about the electronics behind car audio so please forgive me. I can build anything, but I don't know that much about the amp guts/features and what everything truly means. This industry has lots of hidden secrets and tips only the pro's/old school guys know. That's why I asked.

Yes, once lpf is switched to off the output from the amp will be full-range.

The crossover is built in the amp, but it has a switch on outside of the amp {to bypass it} or turn it off.

This was a cute question, I am glad that where able to figure it out, I thought for a second that the amp was always in a fixed lopass config and you were asking if you could bypass the crossover in the preamp section, How funny I go right to over thinking it.

And to answer your second question, I have never had an issue using bare wire strands going into sub connections. I'm sure it would look a little better and be easier if it were soldered tho. Personal preference imho

i would EQ the inputs, not the outputs. Or in other words, EQ the source.
