I broke down and bought an Ace about 6 months ago.Its a small case denso with all the high amp goodies inside.I am impressed especially for the price.Amps are plentiful although the voltage goes up when I hit the gas,but that could be a connection problem.It charges so well I dont even worry about it.I went to a speaker shop and got some 4 gauge cable and wired it straight to the battery.For the money the ace cant be beat,plus there are no mods to fab up.I was a little worried about the long term,being that its a small case{lots of heat buildup},but it hasnt given me the slightest hitch so far.Good alt,I would buy again.
