OEM Stereo to Aftermarket Subs and Amp
I have an 2003 Acura TL-S W/ Navi and i would like to ad an amp and subs. After much reading i have found that i will lose the sound from the nav if i replace the head unit (not to mention the cd changer built into the stereo) and i really dont want to jump through those hoops to make this work.
I would really like to integrate an amp and 2 subs to the stock stereo without replacing everything.
I have heard that you can buy an adapter that provides line level outs, has anyone heard of this? the second option i was told i have is that i can splice the rear deck speakers into the line inputs on the amp (if the amp has them) but they told me first i would have to make sure that the (acura bose) speakers werent powered.
Any help would be appreciated
