boomin Posted August 7, 2010 Report Share Posted August 7, 2010 So I just installed my 4 channel amp, and it works great on low volumes but past 20 it cuts out....the bass works fine all the way up to 35, but the mids/highs amp won't play past 20, it cuts in and out at parts randomly and just won't play...what's wrong with it? Its all wired corectly, the gains are way down, the Bass boost is off, and the HP is set to 120 and the amp is set in HP mode. whats wrong with it?

hdorre Posted August 7, 2010 Report Share Posted August 7, 2010 If the sub amp works, I doubt it's voltage drop. Still check though.

boomin Posted August 7, 2010 Author Report Share Posted August 7, 2010 Grounds are perfect, everything it looking good.... Could it be that I have 4 gauge then a fuse block, then 8 gauge?? idk and the ground is (2) 4 gauges, into a dist block, which from there goes out a 4 gauge than a 8 gauge....could that be the problem (although the sub amp is conected the same way?)

It could be the 8 gauge. How much power is the amp pushing?

boomin Posted August 7, 2010 Author Report Share Posted August 7, 2010 The amp is very small, rated at 250 watts max and 40x4 RMS, alpine MRP250 1.idk, I have it hooked up to my components and the cross overs have both tweet and mid inputs, so i have ch1 going to tweet RIGHT, and ch2 going to mid RIGHT, and ch3 going to tweet LEFT, and ch4 going to mid LEFT. I heard it's a 2 way active setup, and should work like that. 2. Thats what I did, I have (2) 4 gauges going into a dist. block, than from there (1) 4 gauge to sub amp, and (1) 8 gauge to speaker amp (the one thats giveing me trouble) 3. Sub amp is PDX1000, I've never tryed turning it off to see it it still has that problem I will try it in a min, good suggestion. 4. RCA's are perfect all around Quote F/s: 2 custom made boxes, for 1 12" and 2 12" hit me up I'll let em go cheap Link to comment Share on other sites More sharing options...
raolito1980 Posted August 7, 2010 Report Share Posted August 7, 2010 Remote wire secure? Maybe one of your speaker wires are loose behind the speaker and its shorting the amp? Have you checked those?

white4d96 Posted August 7, 2010 Report Share Posted August 7, 2010 Watch the amp when it normally cuts out, see if it's going into protect or just shutting off, that will help you out. Quote Too many projects, too little time... Link to comment Share on other sites More sharing options...
