its seeming to be ok now lol. the amp dint turn on earlia cus the remote wire, even tho it wasnt really changed from when i had my old amp in there. but its ok now, i jus removed the relay.

as for the alpine its ok ish now, the remote wire seemed to make it quiter than it should and the fact the other amp wasnt on it seems, cus the rca goes into my sub amp and out into the alpine. jus need to get a volt meter on her tomoro and set the gains.

lol lol

cheers

right today the amp is orking fine:), i think the problem was the other amp wasn't comin on so there wasn't as much signal goin to the amp.

i set the gains today aswell, but the channel 1+2 are okish, chanel 1 gains was just under 20 volts for my 100 rms and channel 2 on the same gains was on 18 ish volts,

this was about 3 quaters the way up.

and on the other gains for channel 3 and 4 the gains were set all the way to 'max' on the amp(it actually says 'max') and there was only 16 ish volts. but the amp is 4 x 121 rms accordin to the birthsheet test thing.

lol wierd, sounds pretty good tho, deffo worth it :)
