    You threw away money on that "repair" if he did not replace ALL the MOSFETs. This is total half *** and will very likely fail even if you get your electrical system right I wouldn't trust it. Any alleged amp repair person who does not change out ALL MOSFETs from the same batch of replacement parts is either a scammer or completely incompetent. You were told when you asked who the reliable repair people were.

Power supply may not be operating normally even if the amp "works" . Hell some shady places nip out the one or two shorted fets and send you back on your way.
    This dB-R or Ampmedics will do it right. May as well send the amp in to a competent repair person now before it blows beyond hope of repair.

    I'd like to see 2 good size deep cycles in the trunk anyway to run that amp safely. HO alt as well if you can.

    Rise from 1 to 2 ohm.... I don't think you've ever looked at an impedance curve have you? Rising 4 to 10X DC resistance is highly possible. DMM is pretty pointless without a current clamp IMO. Use your ears and use your head and that'll do it if either works as it should.

    Possibly, possibly not. Too many factors, without a proper loudspeaker measureing tool or DMM and current clamp + tone generator you'll never know what's happening at any given frequency.

    This thread is a travesty. OP, please send your amp to a competent repair person and find a competent installer to install and set up your equipment.

    Since when was the gain knob the volume knob? The position of the gain knob is to adjust your noise ceiling so you get less noise.

    It sounds more like ben didn't wanna pay the quoted price to replace all the mosfets, so he cheaped out and just got the 2 bad ones replaced. I don't think it's on the repairer since he quoted the OP a price for it. Whether or not the price is too high or not, the OP still had the chance to ask other people for quotes on the repair to get a better price.

    Benbenondatrack,

    Just giving you ****


    Although, IMO, your charging system did not suffice with the SAZ-3000D, perhaps if you have a good group 31 battery in the trunk though, then just the H/O alternator you have coming will be needed. But, the more the better of course. Did you check and see what exactly that battery in your trunk is yet? 1ohm as your nominal impedance will certainly cause for some decent current draw. If/when you have that AP amplifier tuned and producing as much clean power as you'll be able to obtain, undoubtedly the SA will be louder, ONCE it has the charging system it needs to produce some powah. Takes power to "make" power; even though the SA is going to be much more efficient than the AP, being that it is twice as powerful there is no way around that.
    There are a bunch of people not too far North of you, hell, send some members in Bloomington, IN some PMs (I'll look in my contacts list for the ones I used to talk to). You'll get a lesson and get what you need. And eventually you ought to grab yourself an O-scope if you plan on getting really far into mobile audio.
    Yea man ill appreciate that alot, thanks.

    not true, snoopdan refered me to this guy, so i tried him out. he said more then likely all of the mosfets needed to be replaced, but when i got to the shop, he checked all of them and said only 2 were affected. thats why he only replaced 2. he checked em all

    Find a cheap ac clamp and a dmm. Combine those to see wattages

    Well seeing as with most amps power drops as as the ohms rise I think you might want to look into this a little more, rise is only a need to know thing if your burping a tone and it has to be the same tone you tested with to find the rise so most find the tone that meters the highest then test for rise and make the appropriate adjustments.

    ok guys i guess it was the gain, i turned it up to about maybe 60% and it started coming to life, and i mean loud. i need a way better box but it def. it alot better then the ap 1800 now
