Ipod Problems In Acura TL

I took my 1999 Acura TL to a local audio company and had a new Pioneer 7700 radio installed and had my Ipod hardwired into this - now the radio controls the Ipod as if I were using the Ipod on it's own. Very cool!! I am not good with eletronic equip in my car - however, from what I can understand, the installer had to use a series of "adapters" to get this accomplished.

Problem is - my subwoofer doesn't seem to work. I kept hearing this "hum" from the back of the car when the radio was on - not even on Ipod but on standard radio or CD player - and volume of the radio doesn't make a difference. The hum is there with the volume turned all the day down or up. The radio sounds great, the Ipod works perfectly - it's just the subwoofer.

I took it back to the audio store and the installer says that he didn't realize that the subwoofer was not working. He made a lot of phone calls and finds out that with a Bose speaker system, the subwoofer needs a special adapter as well to make the amp work. Guess what? They don't MAKE this special adapter. He said that I could upgrade my subwoofer to a Pioneer subwoofer or unplug. Well, the hum is so annoying that it is unplugged at the time. I have about $500 in the new radio and install and hate to put another $500 into this!

Any suggestions? The installer is a really nice guy but said this is all he knows about this and if I could find out what he needs to fix this, he will be more than happy to do it - it's just beyond his knowledge level.

Help!! Any ideas?

 

the subwoofer only works with the factory system

 

Thanks brakejobhelp - No adapter is available that you know of? No work-around other than a new subwoofer?

 

actually i take that back... im in the process of updating my tl's audio system, and i've been reading the heck out of posts dealing with the system...

from what ive learned...... ....for the subwoofer the stock bose system was sending a mono signal to the bose eq, which was then sending the signal to the subwoofer amplifier near the back seat... the amp then drives the subwoofer...

apparantly you have to send the correct signal to the amp from your deck, like a mono subwoofer signal...

 

Brakejobhelp - any idea how this is done? I'm just totally dumb (obviously!) when it comes to this kind of stuff!

 

When adding an aftermarket sub you can hack into the RCA's going to the factory sub for a signal. Couldnt you do the reverse of this and run rca's from your new head unit to tap into the factory RCA's for the signal, and also run an amp turn on lead the same way?
Just an idea

 

if you have an aftermarket deck use the rca outputs and get a small 300watt or less amp and power the sub with that.
that is what i did and it works and sounds great
the other option is to use the rca outs on the HU and splice them into the inputs on the oem amp (but they are low out put so you may need something to boost the signal)
