PASMAG | PERFORMANCE AUTO AND SOUND - Precision Power P900.4 Amplifier
It artificially boosts a narrow range of frequencies - usually in the 45hz range. It is RARELY advantageous to add any boost to the signal.
I would set it to 75-80% and use that as the "norm". That way for the rare track that lacks some low end for some reason you can increase it slightly w/o much (any?) risk of stressing the sub, and you'll still have a lot of room to turn it down when you don't want the bass.
It's not ideal, but bass below 30hz is pretty rare. If you notice something way down low just be cautious with the volume knob.
Sure it does. It means the amp must produce the power it says it does at 4 ohms
there are some CEAcertified amps that are poorly made though its not like its the safest decision possible i've seen some CEA amps do horrible square waves on the oscope when it tries to make its power that it states at 2 and one ohms. I put my trust behind reputable and proven/tested brands over some random CEA certified amp anyday.
That sub can take 500 rms safely possibly more but I'm not sure.
Just bought one of these off Amazon for 125 shipped and have it on a couple of single 4 ohm Boston g1 12's. I've always had really good luck with Pioneer amps and this one is no exception. Nicely built and though I probably will never clamp it I would guess it's slightly underrated. Boston g1's are great budget subs too OP. They're not making them anymore so they're going to start getting scarce soon.
I know, I went through that myself with a 2006 big amp I still use compared to some similar class D amps 1/3 of the size from very large and reputable companies costing twice as much and many good reviews, their ratings are given at 14 volts and still my old one with peak ratings of 400 watts less than the newer class D amps simply had way more easy to notice power that could not only be heard but also felt.
Great thanks for sharing that, sounds like pioneer really stteped in to play hard ball and offers great value too.
I think my favorite amp to date was an older RF T1000 I got off CL for 100 bucks. I loved it! But I had better electrical in my car at that time. Now I only run around 500 or less. Only have an 8 gauge amp kit in the car and too lazy to change it. Lol! Besides if you get a decent set-up with a couple 10s or 12s in a good custom ported box the output going from 500rms to 1000 rms isn't that much by ear anyway.
