tacomabanga1986 Posted September 1, 2011 Report Share Posted September 1, 2011 im wondering whats wrong with my amp, it plays perfecly fine, just when i turn it on the protect light comes on and then goes off and cuts on, and it gets really hot its 2ohm stable and i have it wired to 2ohm, what could be the issue? it has a built in fan and it still works, i just wonder why it does this voltage doesn't go below 13v or so, i wonder why it gets hot, all wires are crimped and wrapped with electrical tape, i just dunno what it is i dunno if one of the mosfets or something is causing it to heat up so bad or wut ive got 4guage going to it for power and ground, speakerwire is 16ish guage wire about 2ft long then going to the 14x8 wire i got, i wonder if wire size causes to much resistance and making it get hot?

Skullz Posted September 1, 2011 Report Share Posted September 1, 2011 Take it in and get it looked at before something bad does happen, there just may be some bad caps or something else causing the grief but better to have it checked out anyway.

tacomabanga1986 Posted September 2, 2011 Author Report Share Posted September 2, 2011 i dont have anywhere to send it to, it was from an authorized memphis dealer i got it from tho hell ive got a hifonics 4406 4ch amp setting in a box in my room that i need looked at, everything looks great on it, just powers on and goes str8 to protect i mean ive had it for a good 4 or 5 years and its beast, i wonder if it just gets hot cause its hot out but its out in the open and even with my sub amp wired down to 1ohm the sub amp dont get as hot as the 2ch, hell i couldn't even hold my hand on it for longer than 5-10sec ive never had a amp get this hot and not turn off, works flawlessly tho, great sq and what knot, just not as loud as it used to be tho, i can tell as i turn up the volume the mids n highs tend to stay the same, they get a little louder tho i know my preouts are 6.5v and the amps line input voltage is 2-4v, i dont see this being an issue but i dunno now one day i was jamming to some country and had it cranked and i started to smell something hot like electrical and i felt of the amp so i took it easy on it, i thought it was my subs getting warm but they was still "room temp" this was the country song i was jammin to, http://www.youtube.com/watch?v=Z01GUR24QZk i might just wire up the front comps and see if its the 2ohm load, i'll check the ohm load and what knot tommrow Quote 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...
blankskater08 Posted September 2, 2011 Report Share Posted September 2, 2011 (edited) Have you checked your ground? Ive seen bad grounds cause this before. Also, have you metered your speakers (individually) to make sure they are reading the proper impedance?

BJD3 Posted September 2, 2011 Report Share Posted September 2, 2011 I'd wait for someone else to comment here, but my vote is you're clipping. You have ~6 volt signal leading into an amp that can only handle at most 4v. Like I said I could be wrong, so wait for someone with more knowledge to chime in here.

blankskater08 Posted September 2, 2011 Report Share Posted September 2, 2011 BJD3 could be onto something there, it is possibly that your pre-outs could have an effect on the amp.

CleanSierra Posted September 2, 2011 Report Share Posted September 2, 2011 (edited) Your sub amp doesn't get hot because it's probably a digital mono block. Your amp you're running on the mods/highs is an analog and not as efficient. *Edit: The problem you're having could be a grounded out speaker wire. Thoroughly check all speaker wire and make sure it's not pinched or cut. Bare metal touching an exposed speaker wire could cause a protect.

Ray Posted September 2, 2011 Report Share Posted September 2, 2011 Lmao at digital.. Disconnect all the speakers and see if it still gets hot.
