Hey I have a 99 catera with a Bose Factory System and was wandering if anybody could give me some instruction or direct me to somewhere that could help me on bypassing the factory amp, etc. Any help would be greatly appreciated. THANKS.

aftermarket head unit and run a new system from scratch. then run everything to the back. take out the stock amp and run the wires to the speakers from your new amp. you can't completely bypass the amp with the Bose hu.

I had my system professionally installed with no problems. I remember the installer telling me about having to look for the factory amp.

How much did that set you back if you don't mind me asking?

I just unwired the rear deck speakers and hooked up an amp and subs using that signal. Its fine if you're not looking for anything fantastic. I just wanted a little more kick.

The sub and amp install set me back about $300 CDN includes parts & labour. The deck install was $100 parts & labour. I wasn't charged extra.

Is it possible to just add another amp/sub combo if i have an aftermarket player in. Meaning the Bose stuff can run all the speakers in the car, etc and then just have my aftermarket amp run my subs by just plugging into the headunit?

You can add an amp and sub to complement your current Bose system. All you need is a part that you can connect to your rear speaker wire. I can't remember off hand what these are called but they splice into the wires and allow you to connect two rca cables. I did this in my 98 and was easily able to add a 12" sub to my sound system. I will find a link to the part and post it.

This is what you need. I don't recall how to do the remote turn on. I think it may be built in with this unit (http://cgi.ebay.com/NEW-DB-LINK-DUAL-HI-LO-CONVERTER-RCA-PRE-AMP-LINE-OUT_W0QQitemZ350194887708QQcmdZViewItemQQptZLH_Def aultDomain_0?hash=item51893dec1c&_trksid=p3286.c0.m14&_trkparms=72%3A1234%7C66%3A2%7C65%3A12%7C39%3A1%7C 240%3A1318%7C301%3A1%7C293%3A1%7C294%3A50).

I got a converter box that takes signal from the rear speakers... and turns it into RCA Outputs... then a simple 250W Amp... and a 200W Speaker... a box from walmart... sealed it myself with silicone...

Ended up with Sealed enclosure a 10" Sub with a pretty hefty magnet... not sure how bit it was but I remember it was enormous...

The OEM Bose unit takes care of all other sounds... the sub does the lows... and it sounds fantastic.. .the entire system cost me under 100$...

If you're not looking for superior quality but just need some more bump and planning to keep your exsisting hu, no need for converter boxes or any of that fancy stuff. All you need is a speaker to rca converter wire. http://www.crutchfield.com/p_136CLR2SW/JL-Audio-XB-CLRAIC2-SW.html?search=speaker+to+rca Simply splice this into the wires from the rear deck speakers. You may also need an accessory fuse tap or whatever its called for the remote wire. I tapped that to the factory amp fuse with an inline switch. Works and sounds fantastic :yup:. I installed a 600w kenwood amp hooked to 2 12'' kenwood subs. I love it!

thanks for all the info, i have an aftermarket head unit so would i just be able to plug the amp into the headunit. basically i just wanna make sure it's not going to mess any of the other speakers up?

yeah, should be rca outputs on the back of the aftermarket hu. just run those to your amp.

You probably can't run the Bose speakers on an aftermarket deck. Bose are 2ohm and most decks are made for 4 or 8 ohms. I remeber this being an issue when I did my system.

But the signal would go to Bose amp first, wouldn't that down convert the ohm?
