I can’t get my setup to Thump

Hey guys, just installed an Alpine MRD-M500 amp and SWR-1241D sub. Problem is setting up the amp, instructions first rule is to turn up the headunit volume so the OVER indicator light goes off on the amp, but i turned up the max vol on the HU and it indicator light does not even come on. What is wrong? Also, how to i setup the amp properly? =) thanksMichael Chan

Sounds to me like you HU does not have enough output to drive the amp all the way to "over"... This means you either need a HU that will be more compatible with your amp, or a line driver or some other type of in-line signal processing device with enough output to drive the amp all the way. The HU is the PREFERRED method, as ANY signal increasing device in the line will automatically add its own noise and distortion, IN ADDITION TO amplifying the noise and distoetion already there from the devices before it...It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

is this really whats happening? my deck is an alpine 9833 i think it should be sufficientMichael Chan

I can't tell you. Every install will be a little bit different. As a suggestion, forget the "over" light, and set your gains properly. Do a search on this forum for "Setting Gains", and you will find HUNDREDS of posts regarding the subject...It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice.

Try this, I have the 9835 and the 301 ALpine amp. First set you input switch to 4v, set your input to -6 or 0, set gain to 0, crossover 80/24, sub sonic filter 25, bass boost off, eq off, and be sure to save your settings on the last menu item. Also, I had the same problems setting up my alpine amp. The sub preout on the Alpine only puts out 4v when it is maxed out at 15 on the hu sub volume level. Try the settings above and see how it does. You may have to leave input at 0. At -6 on mine I had to leave the hu sub volume at 13-15, but still did not produce the bass I wanted. At 0 on the input I leave hu sub bass at 7-9 depending how much I want. Bill3508

thanks guys, got it working... i downloaded a PDF of instructions on setting up the MRD-M500 for demo boards on the alpine site. Works great now. What happened was i forgot to save my settings =)Michael Chan
