Hello all I have recently become owner of an Old BD 1500.1 . I picked it up online from a local kid for 150 and hooked it up initially and heard it thump so I agreed and went on my way....I got home installed it and mountd it and started to ajust the gain and levels and all and noticed a kinda high pitched humm or buzz coming from the amplifier...The rca jacks also seemed a bit loose when I plugged my rcas in...
As the amp is definetely not under warranty and had already been peviously opened, I opened it and discovered that the rca jacks were loose on the board as well as the remote power connector being loose on the board. I had a local stereo repair guy (please forgive me for not using a certified rockford repair center) resolder the rca's and the remote connector and I noticed an immediate difference in sound being much more clear, but I still had/do the buzz/humm problem. But being as the amp still performed quite well I kinda brushed it off...
Now I have recently purchased a T2 15 as some of you might have seen on the other threads here, and am using the amp with the sub. I am still experiencing the buzz sound which I would definetely like help on...And now also my amp seems to be going into protection when I turn my deck up to about 65% just after it starts to really bump it cuts out and I have to turn my car off to reset the amp and then it plays again with no problem till I turn it up past that point then "pop". My volume goes to 63 and my amp pops off at 42. I also have to have my gain knob up to almost full to hear real bass before like 40. If I have the gain at say 50% it is really quiet even at higher volumes for a 1500 BD, at least what I would expect for that beast. I know I am only running it at 4 ohms since my sub is a Dual 2 ohm T2 so I am only pulling half the amps power. But shouldn't it pund that T2 even at 50% gain???? I mean come on it's an old school BD1500...
Any help with the noise level problem or lack of noise level expected problem...the whining/buzz noise problem or the protection mode problem.... Lets see Oh I am running 4 gauge power and ground soon to be replaced with 0 gauge...Head unit is a Pioneer F900BT all wire is monster cable including rcas....Amp is model 2001 I think....Here is a pic showing the amp in the bottom if that helps...Sorry for the excessive babbling, I love talking about my fosgate stuff.
Thanks to all who got through that and have or don't have advice!!!

| My deck???? What would be blown on the deck? The buzzing noise stays even when the rcas are unhooked so the only other way the deck and amp are connected would be via the remote power wire...SO I am unsure if the deck is causing the buzz... On the other hand the sub kicking off\amp going into protection, could definetely be due to the deck I guess. I had a ground noise problem with my old BD1000 amp and grounded my rca's coming off my deck to my chassis ground then and it help with the bd1000, however I am not getting any engine noise like I had on the bd 1000 with the bd1500 it just keeps going into protect after about volume 42-44 of 63. The sub should definetely be able to take more power than what its getting so I am left thinking it has to be amp related, lemme know what else besides grounding my rcas which I have already done (thanks though) that might correct these issues. Might have to have the local repair guy do a once over on my deck...or amp... or both. |

Usually when the rca's break loose from the board it causes havoc in your sound. Thumping, loud popping, low sound etc.... Almost every amp I have repaired with broken rca's it has taken out the IN4003 diodes on the board. When these are bad you can have serious feedback in the amp and it will do wierd popping and squeeling noises sometimes. I would check those. As far as the amp cutting out sounds like a voltage issue. My buddy had 2 of those running them at 4 ohms each like you are and at real loud volumes it would cut out and go into protect. He would have to turn the key off then back on and all was good. Check your voltage at the amp when your bumpin hard and see what it is before or when it cuts out. I could be wrong but that amp probably has a regulated power supply. To high or to low of voltage can cause it to cut out. I would add another battery or a hefty capacitor. Those amps draw alot of juice. The T2 needs 1000 watts rms and your only putting 750 to her so yeah your lacking a little sound as compared to what it could sound like. It must be a dual 2 ohm if you are running it a 4 ohms. A dual 4 ohm would better suit that amp. You could also look for a 2 channel 1000 watt amp and bridge it. Hope this helps.......

| I am bringing the amp in tomorrow to the local repair guy to have it all checked out. I will definetely bring what you said to his attention and will let you know what he finds out. And yes it is a dual 2 ohm T2 I had a thread on here and that is the one everyone said to get. Something to the tune of putting too much power to it at because a dual 4 @ 2 ohms would get too much from the amp (around 1800 watts) as I know the old ones like mine were known for being underated...I dont know exactly how much they were underadet but ya. So soing with the advice of the forum here on that thread. I opted for the dual 2 leaving open the option of getting a second one and wiring them together for a 2 ohm load putting about 800-900 to each sub...Still a little underated but better under than over I think. One more quick thing though, could the diodes being bad cause the amp to be quieter than it should be? ANy other side effects besides the noise I mean???Thanks |

| It is a possibility but likely not. Are you running a bass knob? A bass knob can provide +18db of bass boost. A must have, it makes a huge difference in the output of the amp. If you are not running one get one you will be VERY pleased with the difference. I did not see a bass knob wire coming from the amp in your pic. Ask all the dsm and hd guys if they turn the bass knob all the way down on their amps it really takes away from the output, I know because I have tons of each amp. GET A BASS KNOB. You can find them on ebay all the time new and used average is about $30 plus shipping. Keep me posted on what you find out at the repair shop. Later....... |

I agreed 100%, my punch 200ix sounded very weak until I turned up the bass knob on it!!!! Which makes me wonder why Rockford did not include bass knobs on the 250m2 and 500m??? |

| Okay so I went to the local repair shop... All I really got out of the guy after he hooked up my amp and heard the noise I was concerned about and using his volt meter on the speaker inputs, he said hat my ohms were way outta wack and that meant I had a short somewhere... I asked him how much and he just kept telling me how expensive these kind of amps are too fix. I explained that the amp performed quite well and seemed to work okay minus the protection mode at high volumes and the noise in the amp. He said he would try and fix it for 300... I laughed said that was a little outrageous and told him he could have a nice day. Plugged her back in and she works just like before so I think I will get a bass knob as suggested and continue to use the amp until something else happens.I paid 150 for the amp locally off craigslistand had the rca's resoldered and my remote power hookup resoldered for $55.00 as they were loose when I got it. So too much more money and I should just sell it and buy another. Or just keep running this one until it goes out or what not. I am kinda at a loss as to where to go or what to do next. Any advice as to what I should do or what you would do is as always appreciated. |

I would say about 2003 cause the punch line those years were black and the power were grey. Well I would have had him replace the IN4003 diodes and started there. Get a hefty capacitor or add another battery and it probably won't go into protect anymore. Let me know if you sell it, I would be interested. Later bro....

I agree with you sunfire01 the 250m2 and 500m should have run a bass and treble knob as well as the 250m it would have made a huge difference.

if it has the LED on the top its 2003 if not its 2002
sry im bad at keeping up with threads but pioneers are infamous for blowing a fuse they have called the "pico fuse"... causes alot of wierd things to happen in general if its blown. but it doesnt sound like thats the case in ur issue. I would still have tried it anyway just in case it was blown as well as the amp |

Thanks for the info thats good to know. I do not know much about pioneer decks only had 2 my whole life. Always had Alpine or Rockford and a Kenwood once. Alpine and Rockford are my favorites. I have a RFX9420 in every vehicle I own and love them. Later guys....

| Okay well maybe I will go in and see if he can specifically replace those diodes. I will also check the "pico fuse" Any idea where that is located on ir n the deck? My amp has a red led on top so its a 2003 then. Sorry for the delay in response, my baby girl was delivered lastnight, so I am just hopping back on again for the first time. |

| do i know personally no. the ghetto way to fix it is soldering a connection from one of the rcas to the chassis of the radio. but i used to have a pioneer that i had the boss replace the pico fuse either with a straight connection or some resistor i forget |
