i just finished installing my new mbquart 1000.1 amp and second battery and all that, amp turns on and works but i do not have any output from my sub, when i sold my last amp 2 weeks ago i brougt my box and sub inside and took out the sub and unhooked all wiring and i wired it back correctly (i think) i have a alpine type R swr-1242 sorry for the huge pic. but i have the 2 jumper cables red to red and black to black and then for the speaker wire i have negative on far right and positive on the far left. what am i doing wrong? my sub worked fine before

Is there any output at all?

no i dont think so i just checked with a dmm at second bat im getting 12.5(car off) and then put it to the power and ground on amp im getting same volts which means theres no power issue(dont think?) then put it to the speaker terminals on the amp and it reads 0 tried it on dc and ac for that. but my sub worked fine on my last amp 2 weeks ago, i took out my sub just now and double checked connections.

Put your dmm on ohms and check the ohms of your voice coils on your sub.

y are u playing 5hz? did u turn off all the lpf, hpf, bass boost, ssf, etc?

sorry 50hz. i just finished playing around with the amp settings and playing a normal song at 1/2 volume and gain about 1/2 to full i was finally getting a volt read out 1.5-4 and then i tested again on the 50 hz at 3/4 volume and got 0. i emailed maxxsonics just now, and the ebay store i got it from too see if its a manf. defect on the amp or my settings are wrong. but i wont get a response till monday the earliest //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif
