Hey im looking for some addvice. I want to keep my stock ICC unit and run a woofer nothing big just 8'' or 10''. I have looked into running the RCA out the back of the ICC and I can understand the walktrough but I dont trust my soldering. I was told by my mate there is antoher way to connect a sub without running an RCA but im not shore if his info is correct. he showed me some small sub in a box with a small amp. he said you run the power to the amp from battry and then link the speaker wire into the amp on the box and it will use the signal from the speaker wire to work the sub. he sent me a link to a few on ebay ill post links. what id like to know if what he is correct? I realy dont want to get a head unit for alittle more bass I have 4 X 5x7 polk and they sould alot better just looking for some more kick. any help would be great cheers.
