i recently got a regular cab chevy truck and want to get some bass in it. i have an old old spark-o-matic bass cannon laying around so i thought just to start for now i would put it in. i lost the wiring diagram for it though so i dont know how to hook up the switch for it. if anyone knows how to hook it up or where to find it please let me know.

I friend of mine in high school bought 6 of those from wal-mart and put them in the trunk of a Sentra. He would buy one each time he got paid. Holy crap that thing was loud! It rattle like hell, and sounded like mud, but it was louder than anything.

You could try bypassing the switch and hook it up like a normal amplifier. I don't know why those even came with a switch. Do they have a "gain" knob?

i was thinking of maybe doing that but then i dont know which wire is the ignition wire to shut it off when the truck is off. on the bass cannon itself it does have a gain knob.

the head unit is from my 1400 watt taurus sho but i sold it and kept the head unit. it does have preouts for bass, front, and rear. would there be anyway of connecting the speaker wires on the bass cannon into those for the best quality? otherwise i would have to hook into the stock speakers.

I have one of these bass canons, myself.

Red is 12v positive; black is negative.

The 2 green wires connect to the left and right negative speaker terminals - it doesn't matter which goes where. Bass isn't directional. However, the speaker wires are undersized. You should replace them w/ 18ga copper speaker wire.

I just refurbished one of these canons which I've had for @ 20yrs. and installed it in my new(2009) car. They are simply amazing! The speaker has a paper cone w/ a foam surround. It should have disintigrated by now, but there's not one sign of deterioration. Sparkomatic acquired Altec Lansing in the mid-80's and this tube was built @ 1990. I'm sure there's a connection.

I found it very worthwhile to replace the stock speaker wires. The 18ga wire improved the performance dramatically.

Sparkomatic purchased some trademarks in 2000 but not the company. The company was dissolved by Telex in 1998. The company (or a new form of it) came back in 2002 and has been changed multiple times since then.

This thread showed up top of the results for a Google search for "how to wire a Sparkomatic bass cannon". A mate gave me one of these a couple of weeks ago to fit to my track car so that I can have a bit of removable audio whilst travelling long distances to the track, unfortunately it didn't come with any instructions so I had to do some searching! Really useful to know about connecting the two wires to the negatives for the rear speakers. I've wired the live through a relay, switched by the acc. wire from my head unit.

One question about the speaker wiring though, will it matter if I connect it to the negatives of the rear speakers even if there's no rear speakers fitted in the car, or will I have to wire it to the negatives of the front speakers?

If you mean that you intend to wire the sub as the rear speakers, I think that'd work. Connect it to the rear speaker neg outputs at the head unit.

Yes, that would work. You can take the negatives from the front or rear channels. By taking only a negative line of the Left and right channel you are getting a mono full range signal that is then filtered by the bass cannon's internal crossover to give you the bass.

I have already apologized for my sarcasm but I will do so again. I am sorry if my sarcasm was missed and rubbed anybody the wrong way. It has been removed in the spirit of moving forward.

We welcome helpful posts always!
