    Hey everyone,
    I just picked up this amp from a friend of mine as a temporary thing to power my sub. The problem is, it has no instruction manual and because its old I cant find any info on the net. The amp is an AWA model DPA-275, 75w+75w rms bridgable . The amp also has a cable supplied, with rcas and a remote wire at both ends, and a ground coming out at the head unit end.

    The sticker on the bottom reads: 75x2 stereo rms, 150wx1 mono.
    Connections
    Brown R -
    White R +
    Violet L-
    Red L+
    Battery +12V
    Remote +
    Ground -

    First off, I'd like to know what i connect the remote wire to on the head unit end. Is it to the same remote wire the H/U is connected to? Second, what's the deal with the ground coming out only at the H/U end? Finally, what would I need and how would i make a bridging cable for the amp to go to the sub? (I'll make it myself as I have a lot of spare wiring hanging around)

    Cheers all for your help.

    Here's some pictures (excuse the blurriness, but you get the idea)

    ok its simple in ur second pik there is the + - rem quite straight foward + goes to battery - as shorter earth to chasis as possible and rem it to hu to the wire marked remote. as for bridging the wires coming out of the speaker section join the + of one side eg. left to the + side of sub then - side of the right to - of sub. then run rca's you might need to swap the bridging combo to find witch has the most output. then adjust to your liking. btw the orange wire on the rca's is the remote wire just hook the loose end up to the hu remote wire.

    do this all without ripping the car appart then when ur happy with it pull the car appart. no point ripping it appart to find that something is wrong etc. any questions just ask ill be on till bout 8 probs

    enjoy

    hi everyone, i took the amp back this morning and he gave me a boss amp. Hooked it up today fairly easily and i guess it sounds alright for what it is, definately an improvment from before. One thing tho, when i bridged the amp i connected to the two positive terminals of each channel instead of positive of one channel and negative of the other (as previously stated). Its the only way it seemed to work and im assuming the right way. Also put a hefty fuse on the power cable just in case ;-)

    cheers all for your help

    They're on sale, $20 at autobarn. A fire extinguisher could just be the best investment you ever made, seriously. :)
