help, memphis amp not playing very loud

[acold7dusta 10+ year member]

hi guys, i recently bought a Memphis ST-1000D amp used for ~200 bucks and mated it to a Treo 10" SSI dual 2 ohm sub. I wired the sub down to 1 ohm, ( made sure many times it was correct), set the gain on the amp all good, and my box is 1.7 cu ft sealed (i know a lil big...) anyways, it sounds AMAZING but it just doesnt get very loud. It seems like its runnin at ~200 watts. i checked the power/ground, both are fine, and i get a 14v while running. 1 ohm on this amp should be a TON louder. It's rated at 1100 RMS.. my question is how do you find how many watts an amp puts out, or better yet how can i check if my amp is good or not. A friend said that the capacitors inside the amp may be shot. does anybody have any other guesses?

thanks in advanced,

kevin

bump, also i had this amp on a 12" kenwood w3009 sub @ 4 ohms, and the same thing...played amazing but lacked power

well and easy test would be to use a dmm on the amps output terminal and check the voltage

yea, and you have just 1 10" in a sealed enclosure, It is a nice sub but you can't be expecting it to boom your brains out.

if you book them, they will come

i mean

if you port it, the dB's will come... easier said then done, research my lad,search botton is for you

its not that its not hitting high numbers, the amp isnt working right-its not hitting all the notes, and the notes it does hit its very quiet. no its not x/o errorit like hits one note and then the same note a couple seconds later is inaudible. im leanin towards the internals maybe some soldier is loose or somethin?

are you positive that you wired it to one ohm??? you would have wired it parallel to get 1 ohm... are you sure you didn't accidentally do a series for a 4ohm.... b/c then you would be getting about 200w in a 4 ohm rather than rated 1100w @ 1ohm
