It's also a $225 amplifier, which really means it's not 5Kw (I'll show you a real 5Kw amp in a moment for comparison) I also found this: # RMS Power Rating: * 4 ohms: 2250 watts x 1 chan. which I'm still honestly not buying. Even if it could produce that much power, the power supply wouldn't be nearly sufficient to have any reserve power at that output. The amp has 4 30A fuses for a class D amplifier. This means the most power it could actually produce continuously is about 1100 watts RMS (regardless of load) because beyond that, you'd blow fuses. You'd also need a charging system (batteries and alternator) that could handle that sort of draw, which you don't, unless you've spent about $500-1000+ on electrical upgrades for the car. Here's a real 5Kilowatt amplifier, for reference: http://www.rdaudio.net/rd5750/rd5750.htm please scroll down and observe the price. Then, just for kicks, look at this one, too.. just because I love this beast: http://www.rdaudio.net/rd7250/rd7250.htm |

Platinum Member Username: GlasswolfColumbia, SC USA Post Number: 13107 Registered: Dec-03 | a few items to ponder: the Boss amp will work (till it dies) for what you need. It's still an amp and it will produce fairly clean power as long as you do it right. set the gain on the amp properly, don't crank it all the way up to "get more volume or power from the amp" use the correct gauge power and ground wires from teh battery and to chassis respectively, making sure to get a good ground point to bare metal. Wire gauge will depend on length of run based on a current draw peak of (for the one amp alone) 30*4A (fuses) so 120A of current. I've seen some half decent amps from BOSS, although they make a LOT of crap, too. None of their stuff is fantastic, but again, some amps will do fairly well for the pretty cheap relative cost. It will surely hold you till you can do better, later on. something else to consider is that increasing power is the most inefficient means of increasing output (volume.) The easier way to go about that is a more efficient enclosure (higher gain), a more sensitive speaker (more output per watt of input) and a good install, by doing things like sound deadening the interior of the car to reduce resonance that robs you of sound by wasting energy in the form of rattling metal instead of producing music. (increasing the efficiency of the environment.) To double the audible volume of a speaker, (+6 to+10dB increase in volume) you need ten times the power. Double the power to a speaker, and you get +3dB more in volume. This is equal to adding a second speaker and splitting the total power between the two. Noticeable, but not nearly double the output, since the decibel is a log scale, and not a linear scale. You can see why trying to make a system louder by using bigger amplifiers isn't very efficient when you start getting into the need for battery banks, and high output alternators (multiple ones in a car.) |
