subwoofer woes.

6 posts in this topic

Hi there. I just purchased a 2018 spark ls in nightfall grey.

It has the 4 speakers; 2 tweeters and 2 mids in the front doors. I am looking for advice on installing a woofer and amp. I was originally thinking about putting it in the spare tire hole, but I'm not sure if its going to be possible to get a component cable ran out of the head unit. According to dealer, the infotainment unit doesn't support additional wiring.

Hope to hear some insight.    Thanks.

Only option, I can see, is to tap the speaker wire and connect to the sub. If you want to retain OEM head unit.

Line output converter. Just put an amp and 10"sub in my 15 spark. It connects to the factory stereo and lets you connect it to an amp. Works amazing. Part is only $15-30.

I did this with a bazooka i ordered on ebay. Taps to speaker wire and radio power.  Car is small so a small sub works great

luckily, even while cars have improved a long way over the decades, adding and amp and sub to a factory radio has not changed one single bit (other than there being more choices for parts to use) in the last 30 years...

 

step one: run a power wire from the battery.

 

Step two: run a ground wire to the body.

 

Step three: depending on your amp's inputs, either install a LOC (Line Output Converter) behind the radio or just run speaker wires tapped into the rear speaker's feed to the amps high level inputs.

 

Step four: run speaker wire from the amp to the sub/box

 

Step five, either turn on signal sense or run a turn on wire to a wire in the car that turns on with the key.

 

 

OR

 

step one: take the car somewhere and pay somebody to do the work for you.

 

 

this has been done many many times and there are more than a few threads on here showing exactly how to do it and what is possible.

 

just one example:
