Add subs to stock radio

[reeferman420]

I have an 85 riviera with a radio and 11 cd changer from a new gm truck installed and because of this I want to keep it because I bought it like this and it had a good amount invested in it already. I have alpines all around but i would like to add subwoofers could i do this I have installed alot of car sound systems in the past but I alwasys just used the preout on the aftermarket radio to run to the subs so how would I go about installing this with my stock radio?

You need to find something called a Line Out Convertor, or LOC for short. Easily found at any local dealer, Best Buy or Circuit City.

For good quality LOC's, check out: http://davidnavone.com/

Or if you dont want your subs poppin all the time, and you have a few extra bucks , look at the jl cleansweep

also one last question will this affect the quality of sound using this or would it sound just as good as using a aftermarket radio with preouts

 

[reeferman420]

anyone know if this will sound good or will it be all distorted???

It shouldn't be distorted.

An after radio might sound a little better though.

If your using a stock headunit then you won't get as much out of the subs. I've tried installing a subwoofer using my stock headunit and wasn't pleased at all. Then I changed to a aftermarket headunit and what a difference it made.

Hell for the price of that you might as well go out and buy a nice headunit.

are you could splice into the rear set of speakers and use the high-input on the amp

If you do go this route I would get an amp that has a remote that is not a bass boost but a remote gain control so you can control the output of your sub, otherwise you will have to use the bass/treble control on the stock hu and this will effect the door speakers and also send upper freq to your sub even with the subs crossover you will notice the upper bass coming through as you turn up the bass on the HU.

although it can work i highly highly suggest not going this route. either get a loc or a new radio... just my 2 cents
