Bash 300S Digital Subwoofer Plate Amplifier 300W RMS
Does heat become an issue if I build a box for this amp?
I'm only a budding enthusiast so my friend has been teaching me a few things about amps etc. If I built a wooden box for this, would I need some sort of heatsink or leave the back open?
I just built a sub using this amp for a church youth group. Driving a 12" speaker, this baby is LOUD! You can imagine the kind of workout the amp gets. I too worry about heat, so I checked the amp after a hard night - felt like an elevated body temperature. If it runs that cool under this kind of load it should last a long time. The amp sinks its heat to the panel face, so just be sure and give it some space, and maybe some air.

Q: About how to connect the Bash 300 to my sub, and what are the front left and right "Hi level inputs" for?
hey i might get one of these Bash amps one day, I've seen parts of videos online of how people have hooked them up. some put them directly onto the subwoofer box. which is cool if you want it permanent like that. i was thinking of building a box just for the amp and running the wire to my sub. How long is the given wire in the package? can i replace this wire with my own or, if i have to, extend it? also what are the front inputs for?(HI LEVEL INPUTS(LEFT & RIGHT)) I'm new to plate amps.
Partial answer:High-level inputs general mean amplified signal. That is, instead of a pre-amp out from your source (receiver, probably), you could run speaker cables to those inputs, which would blow out line-level inputs.

two for one speaker
Is it possible, in a safe way, to use two of these for one subwoofer? I have dayton audio 15 inch sub with 800w. Thanks.
For the subwoofer you have, no this would not be possible. To connect two amps to a single speaker to provide more power to it, there are two ways to do this:1. If the speaker is a dual voice-coil (DVC) speaker, then connect one amp to each voice coil.2. Connect the two amps in bridged modeI'm not sure exactly which model of 15" Dayton 800W sub you have, but all of the ones listed here on Parts Express with those specs are single voice-coil subs with a 4 ohm impedance. So, because they are all single voice-coil, you cannot do a DVC setup. Also, since the sub has a 4 ohm impedance, you would not be able to safely connect two of these particular amps in a bridged mode and power this sub. This is because when connecting an amp in bridged mode, the minimum load impedance is twice that of the regular minimum load impedance. So, the minimum load impedance when bridging two of these amps would be 8 ohms.If you want to use your 800W sub to its fullest potential then I would suggest using a more powerful amp.

Can this amplifier be used with a power supply of 220V outside US ?
Is there a way to increase the Low Pass Cutoff from 330Hz in the stock model to 700Hz low pass for use in powered speaker projects ?
my electrician friend put a jumper on it to make it 220v, saw it when we were putting the amp on the sub box, i just forgot to take pictures

Can you use other speaker wire to connect the amp to the driver/switch out the stock output wire for longer wire? For example 16 or 12 gauge wire.
I am using this amp in a separate box than the driver and need to use longer wires than those that come stock with the amplifier. Also, I am hooking this to a dual voice coil subwoofer that works best with about 12 gauge speaker wire. Is this going to be possible?
Yes, as long as you observe proper polarity and insure you do not allow a stray strand of wire to cross terminals and create a short, there is no reason why you can't build your own speaker wire system to transfer to your doul voice coil speaker. Good Luck

Does this amp have a bass boost and/or a subsonic filter. If so, what are the Hz values for each?
Yes it does the default values for it are 1dB boost at 30hz and the cutoff frequency is set at 17.7hz, I am unsure of what order the high pass is but I suspect it's a first order high pass ( 6db/octave)Anyway you can easily change those by changing two resistors on the amp's board to the values given on the amp's boost table:http://www.parts-express.com/pdf/300-750.pdf
