[QUOTE="forbidden, post: 1847921, member: 552189"] Reading comprehension 101. "why people always want to throw in second batteries to a weak electrical system is beyond me" Throwing a second battery into your system is not going to accomplish much if anything unless you want to play the system with the engine not running. Hows about you have a crapload of current draw, too small of wiring on power and grounds and more than likely way too small an alternator. The alternator runs the whole show when the vehicle is running. If your voltage is dropping, the battery is dumping all it can into the circuit to try and help out the alternator. What you need to do is find out the resistance on the ground return to your battery. Visit [URL="http://www.the12volt.com"]http://www.the12volt.com[/URL] and read my grounding sticky there. Next you need to use 0 gauge front to back. You need to do the big 3, no exceptions here in 0 gauge. Run as large as a power and ground wire to the amps as you can. Voltage drops are indeed hard things. Yes it can cause a amp to clip prematurely. Now some amps use regulated power supplies and might be fine down that low of voltage, some amps use unregulated power supplies, as power drops, so does output levels and the point of clipping.
