Why didn't this work?
 

I tapped into the positive and negative wires coming from the factory amp to the Bose sub and split it off to my 2 10" Rockfords. All that happened was my Bose sub didn't work. Then when I took the taps off the wires the Bose sub started working again. I was trying to get some of the amp power goin to the Bose sub to power my 10s. Why didn't this work?

do you have an aftermarket deck if so make sure the remote wire for the boseis hooked up to your deck

never mind what i said

You might want to get another amp. If I am correct, the Bose amp does not have enough power to amplify 2 subs.

Thanx. I was told a good amp to go w/ my 2 10" Rockford Z's would be the Rockford Power 350s. I found it on sounddomain.com for $180. Does anyone know if there is anywhere where I can get it cheaper?

When you say that you split off to the 2 rockfords did you split off the signal to an amp that then went to the 2 RF subs, or did you use the Bose amp to directly push the RFs?

Well to go into detail I used 2 actual wire taps and tapped into the black(neg) and white(pos) wires coming from the Bose amp to the Bose sub and twisted 2 wires together for the pos and twisted 2 together for the neg and then seperated the positive wires and put them into the positive part for the 2 RFs and did the same w/ the negative.

Okay, I see.

Well, like it was said above, my guess would be that the Bose amp is not designed to run 2 subs, nor to run at the impedence load that yuo created. I would definately add the suggested amp.

Yeah I'm tryin to get the money. I wanna keep it RF and not cross brands. So as I said before I'm gettin the RF Power 350s for $180. The 10s I have aren't the best but I got them b/c I couldn't pass up the deal. A friend wanted 12s so he sold them to me for $30 all together and I made my box.
