Hook your DMM's contacts directly to the terminals on the amp where the wire is connected. But I can already tell you this, the voltage drop will be even more there (lower voltage) than at the amp. 10 volts is already major voltage drop, a potentially harmful amount for your equipment (especially the amplifier). I suggest fixing whatever flaw you have in your system thats creating this much drop.

Could this be why my amp gets hot and gos into protecting mode after 5 songs?

how long is the 4 ga run from battery to amp?

Power Cable Chart | KICKER, your amps pulls 140 amps of current, you should be at 1/0 ga. i would double check your ground too! thats a waaaaayyy low voltage drop!

17 ft it sits at 13.7 until i crank it up ground is 5 ft long

Hell 13.7 is not a good starting voltage.. so id say up ur wire to 1/0 do the big 3 check ur groundand have some one check ur alt and batt

sounds like you have been slowly killing your alternator and in return the battery has sufferd also

i suggest getting on ebay and buying a high amp alternator there ( ive had great success with HI AMPS POWERMAX and DBELECTRICAL)

and then replace battery also if needed or give it a good proper charge and see what it rests at

edit.. do the big 3 also

0g is best

I have a regular battery under the hood and a stock 103 amp alternator. I had the battery n alternator tested, they both passed. I have extra 4 gauge, will that b sufficient enuf or should i buy hot gauge for the big 3? Will my system pound harder with the big3? I bought the cheapest head unit hey had at best buy, that wouldnt have anything to do with it, would it?
