running speakers to amp?

[GdUp4RmFtUp]

I have a couple questions...Hopefully you guys could help me out. I have a head unit with one set or rca's and i already connected those to a 2ch amp which goes to my two subs. Now I want to connect another amp which is gonna go to my front and back speakers but theres no more rca's to connect them to??

Connect A new RCA from your amp's output to your new Amp's input.

Explain More clear.
One RCA, connect from your radio to your 2ch amp input.
Second RCA connect from your 2ch amp output to your NEW amp's input.

Thanks never would have thought of that. Now a couple more questions. How do i connect the front and rear speakers to the amp? Do I leave the tweeters alone? Thanks again

Does the interfire amp have RCA outputs? The front speakers consist of a woofer/mid and then a seperate tweeter so there are two pairs of wires for each door. I would suggest getting a 4 channel amp for your front and back speakers. The way I am running my amp is I have the front woofer/mid and tweeter wired in parallel so this is presenting a 2 ohm load to each front two channels on my amp (I'm assuming that these speakers are 4 ohms). I connected each rear speaker to its respective channel on the other two outputs of my amp. I've run it this way for a year with about 80 watts up front due to the 2 ohm load and about 50 watts in the rear without any problems on the stock speakers.

So I have to run new wires from my stock speakers to the amp? And if I run the mid and the tweeter into the same channel would I need a crossover? Thanks a lot for all the info...really helping me out.

Yes you have to run new wires from your stock speakers to the amp. But i doubt that you need a crossover.
