Ok thanks. Never knew that

I bought a Boss audio blx 3500m amp about a year ago when i knew nothing about car audio and just tried to buy the cheapest amp i could find. I've read that boss audio products aren't that good. Is this true and does this reputation also go with this amp. I'm just wondering because i had it hooked up to a Boston Acoustics g5 12" single 4 ohm and the sub made a funky slapping sound (not tinsel lead slap, those are fine) that i could just not live with. Could this be a problem with the amp.

Cool thanks for the replies. I never heard any clipping with the sub and it got pretty loud. I thought clipping only happens when you get an underpowered amp and push it too far and it sends a square wave instead of a sine wave. The amp would probably only go over 1000 watts rms if put on a 1 ohm load which it might not even be stable at but it claims it can so i couldn't be overpowering the sub too much. Well i don't have the sub anymore but i was just curious because it was my first set up and i know i didn't choose the best amp (probably should have got a sundown amp) but i tried to go for a sq sub. It sounded good, don't get me wrong, but that sound it made at that frequency just annoyed the crap out of me. I now have my heart set on a Sounsplinter rl-p 12 or 15.

More info on the sound. It only happened at a certain frequency range when playing songs i think below 50 or 40 hz. I played test tones from 20 to 80 hz and couldn't hear that sound it only came on during music. It sounded kinda like when you open your mouth and hit yourself on top of the head with your knuckles. Weird i know but it sounded similar to that. The amp itself had a db boost 0-18 db and a level bass boost which i guess would be the gain. Both nobs when turned would make the sub play louder so i don't know which is for what. The instruction booklet it came with didn't even mention anything about these nobs.

Yeah i know. As i stated earlier i said i bought when i knew nothing about car audio when i bought it. I had several boxes for the sub. 2 sealed boxes, one with a passive radiator and one with just the sub and 2 ported boxes, one slot port and the other a flared port both 2 cu. ft and tuned to 32 hz or just a little higher. That noise came with every box i put it in. I checked the sub, nothing was wrong with it visibly and i even got a recone for it, same noise came. I guess this is more of a sub question than an amp one. I'm just wondering because there has to be a reason Boston Acoustics stopped selling this model.

aren't they good down to .5 ohms. I not sure but iv'e heard they're good amps.

I think that's just a little too much to much for the average consumer but of course they don't look at this kind of quality anyway. They just like their mtx and kicker lol. Retards. I say go for it. Just my 2 cents.
