How to fix that Infinity Amp.

OK, so a member here hooked me up with an Infinity Amp for my WJ, and it worked great for a while, then kind of.......puked.

I don't have time or money to completely replace my sound system, so I had a thought. I read on WJJeeps that the stereo put out the normal 60-whatever watts, which is fine for me. So, me and a buddy whipped out an oscilloscope, to check and see if we actually get that.

We jumpered a speaker at the amp connector, and took a reading....


Success! Now we just had to modify the amp......nothing a band saw can't handle!


We cut the connector end right off of it, and used that to create a bypass that goes right into the amp casing. This way, the car's original wiring is unmolested, and all the surgery is contained within the amp case.....


As you see, the diagram is nicely printed, right on the board. Made this about a twenty minute deal.

Oh, and my sound system doesn't cut out anymore.

or you could have easily just cut out the two connectors that attach to the infinity amp and wired the speakers directly together, but hey it looks like you got some good experience with soldering on circuit boards!

But as stated the entire purpose here was to not modify the existing wiring, maybe in the future he gets an amp he could throw it back in.

A+ for sounding like an idiot and not reading the entire post. Take your arrogance elsewhere.

OP: nice job on that! I like the stock look. I've been thinking about doing something similar since I've replace the stock headunit, I don't have much need for the crappy infinity amp.

My front speakers and tweeters are coming in low. Will doing this bypass fix that issue?

Maybe. Tough to say for certain. My dash speakers are blown, and doing this mod cuts them out.

I should elaborate....my amp was cutting out totally, and at times, introducing noise into the sound system. So, unless you are dying to have a four speaker system, and wanting the amp gone, because you know it's bad, this may not be the way to go. I'm not requiring anything that wins sound competitions, so it's fine for me.
