So I bought JJs stealth box, a JL Audio 250/1 amp and a JL Audio 10w0 I found a mobile installer on CL but wanted to check here to get some prius specific advice on the following questions and if I missed anything please share your wisdom I rear that the signal should be tapped of the front speakers, upstream of the stock amp..how important is this? Whats the best wire to tap for remote? The prius battery is small, i have a 250w rms amp will this drain the battery ?
