I am interested in those who kept the Bose HU but added couple of subs and an amp..

I have a 600watt amp.. 4 way bridgable i believe.. not sure what other specs are on it.. and 3 10's JBL in a box... now I wanna know how to set it up.. i know i need an adapter.. but will this be enough to make 3 10's work.. or should i only use 2 10's?

I've got two 12s with Bose system. Do you know what the impedence rating is for those subs? Also, you said your amp is 4 way bridgeable. Is it bridgeable to one channel, or just two? Matching the impedence of the amp to the speakers is the key. A mismatch could damage your stuff. If your subs are 4ohm each, I would just use two and hook the amp up 2-channel If your amp is bridgeable to one channel, you may be able to use all three.

I used the PAC AOEM-NIS2 to add an Eclipse Aluminum 12 and powered it with a Alpine MRD-M500....WOW! It will THUMP!!! It can sound much better than stock, but now the bass tends to overpower the rest of the system if I turn the bass up.

I think they might say the model # on the magnet. Try taking one out of the box and see

if ur amp have speaker level input then there is no adaptor needed...just tap into the audio signal before it gets amplified by the bose amp...then just adjust ur gain accordingly...u can also use the power lead for the bose amp as an remote for the amp...now if ur amp don't have that...which alot of amps now days should have...u need to buy speaker to rca adaptor...very cheap..like 15 bux...

Don't use speaker level inputs on the amp. The additional resistance will cause the Bose amp/HU to overwork itself and burn out (per CarStereoHelp.com, a place that repairs Bose systems). Plus, the sound will not be as loud (nor as clean) as you can get it using the PAC kit.

In the Audio Forum FAQ, I posted some links that will help you find what you are looking for. The PAC AOEM-NIS2 is the kit that you'll need.

i tried... the speakers are outta the box. I have no idea how to tell... i can't believe they didn't put a number on it. The only thing on is it a big JL Audio sticker on the back of the magnet.

u tap into the unamplified signal...shouldn't effect the bose amp because it is before the amp...if u tap after the bose amp then the signal is double amplified...meaning ur aftermarket amplifier will amplify the noise along w/ the audio...plus the signal is just for the woofers...human ears could hardly tell the difference...that adaptor u r referring to is good...but it's cost more then the adaptor i'm talking about...

Just an idea. Check if there is a JL Audio dealer in your area and bring the sub in to them. They might be your best bet to find out what they are. I looked at all the 10" JL subs before I bought mine, there is a lot of physical difference in the speakers-magnet sizes, metal used in construction of the frame, etc. By the way, my system sound MUCH better with just getting new subs and trashing the BOSE sub.

i ran speaker level input from one speaker to the amp/sub and every time i pressed gas i would hear anoying high pitch noise...couldnt handle it after 2 weeks and disconnected everything...i heard that audi has the same problem when connected aftermarket to factory HU

That sounds like a grounding issue. What did you have the amp grounded to?

Did you actually do it this way, or is this just a theory? I tried that and it sounded like crap. I then did it after the amplifier (against recommendations) and it sounds fine for just the sbus. You are right about the double amplification, but for subs it weas not a nbig deal.

I need to get an adapter, but I had other issues that had to be dealt with first.

I will look into the specs of the amp and the subs.. im not really sure.. i got it for free from a friend...

I went with an Infinity Basslink and kept the Bose in. I took out the Bose sub however and used the hole as a port. Sounds awesome. I don't listen to the rap stuff so I don't what kind of thump you're lookin for, but I love the Basslink. I have a ton of trunk room too!

I recently just installed my Coustic D-block amp and added 2 Coustic CarbonFiber 10"s..kept the BOSE HU..all you need is the PAC AOEM-NIS2 kit..simple plug-n-play and runs about $60...I ordered mine from http://www.affsave.com/pac5.htm and was able to get it "next-day" shipping..good customer service! The sound is real clean and the bass hits hard..gotta keep my Bass level at -5 and had to turn down my gains on the amp...good way to save money if you keep the stock BOSE HU..plus u cant beat a in-dash 6 cd changer!

yep...i've done it both way also...after thinking it over and over...i had better result w/ before the amp...yes...for just subs...after is fine...it mite even be louder cuz signal is stronger...maybe that was ur case...i found less hiss noise tapping in before the amp...

Makes sense. It was not about loudess when I went before the amp, it was more the fact that the signal sounded all distorted. When i go to add front stage off of the same input signal I have a feeling that your experiences with hiss will be apparent. On a sub the line hiss is not heard, but on highs it will be much more noticable.
