    Hmm. There's an existing amp? Where is it? Is it attached directly to speakers? I think you should run another amp and attach the new speaker to it.. This way you don't disturb what's already connected. If you did, all your other speakers would lose power while the amp you already have - which was probably designed perfectly to power your current speakers - will use power to run the new speaker...

    Did that make any sense?

    www.crutchfield.com 1-888-955-6000. They should be able to give you an answer. Their customer information line is VERY good.

    I personally haven't ripped my dash apart yet... However if for some reason they had the foresight to install rca jack/pre outs in the back of the factory deck then you are set. If not then you need a line level converter and a wire harness for the system. Unless you feel like splicing into the factory wiring which I highly discourage. It's like painting the car with house paint. Anyways get a pair of RCA's to the trunk and mount a decent amp back there and run them subs.

    I have 4 12" JL Audio's to install. I need to make a new box because the trunk is 2" narrower than my contour was.

    It's a simple task to tap into the line-level wires to either rear speaker and then either use line-level inputs, or a converter to RCA's. That's you input. All you need then is an amp and sub, or a powered sub, and some power and ground. Don't forget to run the turn-on signal wire too which can easily be tapped into the OEM antenna relay. I would also recommend a cross-over filter for the unit. I did it on mine and it sounds great.

    hmmm i would go with the hi-lo convertor...

    also...using antenna as a turn on? As a car audio installer, i know that doesnt have good results most of the time... sometimes, it just doesnt work on certain cars. i would find the turn on wire ON the bose amp with a test light.

    I recently had a 10" subwoofer (JL 10IB4) installed in the existing hole on the rear seat panel. Also installed a JL 250/1 amp (attached to rear seat in the trunk). Had a bass control installed below and to the right of the steering column. It made the Bose CD system sound much better - fuller sound all around & improved the kick in the bass response for the low end sound that was lacking.

    Did this on a 2000 STS for a total price of $600 (included components, install, tax)...not a bad deal if you're not willing to tackle it yourself.

    JerseyMan. You may consider starting a new topic in regards to this. It sounds like you did some good stuff to your system. I know I'll come looking for it when I get my STS..

    Throw away bose?

    I wouldnt throw away the bose systems necessarily. I took my bose head unit to a repair place and they said that most aftermarket stuff cant compare to factory. I was shocked, I have spent a ton of money on amps, subs, speakers..ect In fact I was listening to a good old Heart song and my headbanger friend even was astonished on the clarity of the bose 6 speaker system my DTS has. In fact I have 2 10" subs, 2 600 watt amps, a nice JVC head unit that I wont use after hearing the stock bose....just my opinion.
