Guest jbinn Posted January 7, 2010 Report Share Posted January 7, 2010 I'll do that tommorow as I go through my checklist of to-do's but honestly that can't be the problem. honestly I don't care much if I blew my amp, but I hope my subs fine I JUST GOT IT a week ago... and I've gingered it. can anyone confirm my sub is good? how do i check the coils on my subwoofer to confirm they are fine?

Boon Posted January 7, 2010 Report Share Posted January 7, 2010 You're losing 3 volts between your battery and your amp. Something is wrong with your power wire/fuse/ground. 10.x volts fo' life! Link to comment Share on other sites More sharing options...
Guest jbinn Posted January 7, 2010 Report Share Posted January 7, 2010 You're losing 3 volts between your battery and your amp. Something is wrong with your power wire/fuse/ground. So what do you recommend to test that theory? and could this even cause my problem? Link to comment Share on other sites More sharing options...
-Hobby- Posted January 7, 2010 Report Share Posted January 7, 2010 I checked with DMM my battery DC and it was 14.50 with volume @ 28 for a few mins...I check amp input from power wire it was 11v Not a theory its what you checked with the DMM. Fix your ground. Link to comment Share on other sites More sharing options...
-Hobby- Posted January 7, 2010 Report Share Posted January 7, 2010 and could this even cause my problem That is why you started this thread isnt it? The problem lol Not trying to bust your balls, just pointing out the obvious. You ought to put the right fuse in the amp too. Should be either 2-20 amp fuses or 2-25 amp. Never seen them mixed like that before. What amp is that in the pict the Alpine? Link to comment Share on other sites More sharing options...
Guest jbinn Posted January 8, 2010 Report Share Posted January 8, 2010 Alpine MRP-450 400RMS x 1 @ 2ohm hmm I did fix my ground, I can try another spot but I don't know any spots better I can shave that paint but the ground hasnt given me a problem until now it appears... could it be my power wire? how do I get that extra 3v that I need for me amp I mean im confused elaborate with me One person says 11V into the amp is fine, Im picking up a 20a fuse for my amp to replace the 25, I reinsterted my ground wire instead of my crappy one.. does ANYONE think my subs blown?

tacomabanga1986 Posted January 8, 2010 Report Share Posted January 8, 2010 if i was u ied get me a 4guage kit that steps down to 8guage to help with current flow and try not to do ur wires like that cause it looks like from pics that u cut off 30% of the strands to stick the wires in the amp my buddy ran 2 of the 350version of this amp to my old set of rockford punch he2 n had no problem at all runnin at 2ohm on both off a 4guage main power stepped down to 2 8guage's in his lil nissan and my buddies old 350's did around 700rms @2ohm to those rockfords when we tested em so ya that amp should be givein that sub a good 600rms at least, imo ied change the fuses to w/e the amp calls for so it has the right ammount of fuseing n ied get a better wire kit n if i was u ied use a self tapping screw/bolt n make a new ground somewere, just take some 60-80 grit sandpaper n skuff off the paint somewere close to amp n put it there when i had my mtx500d in my honda i just had it grounded to one of the back speaker pod thing bolts that was threw bare mettle n i had mine wired down to 1ohm for some time not knowing it was internally bridged but it worked fine for 2 or 3 yrs till i switched it back to 4ohm and had no issues cuttin off but i had 4guage power n ground if u can get 4guage to fit ied do it, u can get ground lugs kinda like this from any electrical supply store n take out the screw on the amp n put this in there n then put the screw back threw it, thats what i did on my mtx500d and it worked like a charm, these are pure copper n u can get em for around $1-$2 each i think thats what i got mine for but ied try that first^ might be wire issues due to how u got ur wires stripped back with not many strands goin to amp, and does the amp cut off or sub just stop playing? here's a link to my system 99 toyota tacoma , 2 mtx 8000 1504's in a sealed downfire , 1000w memphis amp here's a link to my other system my 90 geo prizm test car heres a thread i got of new songs u can dl that are legal = Some Good Bangage/you Can Dl These Free And Legit Link to comment Share on other sites More sharing options...
-Hobby- Posted January 8, 2010 Report Share Posted January 8, 2010 If the sub was blown it wouldnt play so probably not. Unless each coil is wired separately to the amp, then it could be playing on one coil. Take the sub out and Ohm out the coils and see what each one reads. Should read close or the same as each other. That amp takes 2 25amp fuses not 20amp. Link to comment Share on other sites More sharing options...
