Hey, I have a 1999 Deville "vintage edition", it has a 12 disc CD changer, tape deck and am/fm radio. i wanted to know how i would go about installing a small amp and sub to the stock system. If anyone could help me out with this I'd appreciate it.

whats your budget? How many subs do you want to do? Do you want mind blowing bass or just something better than stock? are you willing to give up some space in the trunk?

just a few questions you should answer before we can move on.

im looking to do the same ...i got a 98' deville with the delco tape and 12 cd changer in the trunk.....i have one of those PAC line converters...and i have a 400watt amp with a 12" sub...nothing dramatic...just want a little more thump...but where exactly should the line converter be mounted?...behind the head unit?? theres not much space....anyway it looks a little complicated to install this line converter and i dont know the performance of it....so i might wait a while....and try get a clean sweep and have someone install it.

I have my system set up that way and I am running 2 Kicker CVR 12" powered by a Directed d1200 amp and a volvenhagen 2 farad capacitor with a 4ga wiring kit, and it is by far the one of the hardest hitting systems i have ever owned.

Hello,

If you just want to install a subwoofer&amp it is relatively easy. Like previously menitoned, a line level converter is needed. The model I used is a SNI-35 and PAC (Pacific Audio Company) makes it and it is inexpensive. You want to put this device in the trunk and tap the signal off one of the rear deck speakers.

The sub is going to need to be in a box and the amp is going to need a wiring kit. You may be able to get away with 8 gauge depending on the power of your amp (more power means it needs thicker wire). Check the amp's manual it will normally say the minimum gauge required (remember lower gauge means thicker wire). The hardest part may be wiring the 12 volt turn on lead (needed if your amp doesn't have signal sensing) that tells the amp to turn on. I went with a JL 10w3v3 in a sealed box with a JL A1400 amp (500 watts) and it sounds great.

The only problem is that with the stock headunit, you will have no control over the sub. The sub volume will go up and down with the main stereo volume, but it is nice to be able to control the sub volume independently for a variety of reasons (i.e late at night, some songs have a lot/too much bass, sometimes you want to rock out w/lots of bass etc.)

A great device that allows you to do this is the JL Audio CL-RLC (google it). It can be used with any brand sub/amp combo that you choose. It comes with a volume knob that goes from the trunk (where the amp is) up to the driver. Mine is mounted low near where the drivers right knee would be. I can control the volume of the sub, from max to mute...the thing is great!
Hope this helps.
