Posted August 2, 200520 yr Just put in my 12" Rl-p it pounds. But what settings should I set my amplifer to?Alpine MRD-M605600WRMS x 1 @ 2ohms1.21 cu. ft. internal volumeHere are the settings that are available, as per the user manual:Crossover Frequency Adjustment KnobPermits adjustment of the crossover frequency, byrotating the knob to select any frequency between30 to 200 Hz as the crossover point.9 Lowpass Filter Slope Selector SwitchThe Lowpass Filter slope can be set for either12dB/oct. or 24dB/oct..it does sound very nice, but i was hoping the bass would be tighter. so im thinking about getting a ported box from circuit city or something just to see how it sounds.any recomendations about what frequency to get the box tuned for? i've seen them on ebay between 30-42hz.TIA
August 2, 200520 yr you're not going to get tigher bass than a sealed box. ported box will be louder though.
August 2, 200520 yr Author What headunit?<{POST_SNAPBACK}>stock huaudi symphony using blaupunkt adapter to get RCA outs2000-2001 b5 audi uniti know thats my limiting factor and it would sound much much better with a different HU. however, there is no dash kit for my car year. i can only go custom, which doesnt ever look completely stock.it does have a 4 level eq for front/rear speaks though. plus the regular bass/treble/mid adjustment. decent.
August 2, 200520 yr Author Do you know how many volts are outputted from the rca adapter?<{POST_SNAPBACK}>no idea, ive looked before haven't been able to find it.is this info helping you tell me what should i set the crossover/lowpass filter slope to on my amp?
August 2, 200520 yr It does help to set the correct gain.This what you have?http://www.midwestelectronics.com/product_...products_id/140Other than the gain, I would set everything like this:LP Filter: 72HzLP Slope: -24dB/octSubsonic filter: OFFPhase: 0And to set the gain...Read the gain setting tutorial, and adjust the gain setting on the amp until it is the closest to the voltage it should be.
