So i've had a Bash 300 amp from CSS sitting around for probably a couple years, can't remember exactly how long. I've hooked it up occasionally to a few various woofers and subs but now i'm finally making a sub with an SDX10 and heres my issue. Right now it's playing quietly and the sub is just sitting in free air on the ground. However, to get any perceivable sound i have to have the level knob on the BASH turned ALL the way up. Is there something wrong with the amp? I am wondering how far other BASH 300 users have to set the level to get a good musical blend?
I seem to recall that when i bought the amp, i didn't have to go very much past 1/3 to get extremely loud results but i could be imagining things
I tried a different rca cable, a different driver and still the same thing. My dac puts out 2.25 volts at 700-800 ohms (kinda high i know) into a passive preamp which is splitting the signal to the sub amp and mains amp. Maybe that's the issue. Any thoughts?

Scary letting things sitting around...then the warranty runs out - It happens 😱
Although, I bet your okay, did you try different (other) hookup combinations?

I just put one in service after both my Rockford/Haflers failed. They tend to have cheap pots in them and it may have gotten dirty. I find I have to leave mine powered up as the auto sense is not sensitive enough.
You said your sub is in free air. Well, that's your problem. All you are doing is making air move from one side of the cone to the other. Build a box, or just put it in a piece of cardboard in the window to make it an IB. Then see how the amp works.

Thanks guys. Now that it's in a box, it does have more volume however still seems like it should go a lot louder. Cranking the sub level all the way gets it a little louder than the optimal blend, so I can live with this.
Try "warming up" the gain pot (crank it to max then min a bunch of times). Maybe it is dirty as previously mentioned. I have also just ordered a SDX10+Bash300 with 2 PRs. If I like it, I will order another for a pair of SDX10's for near LP positioning for movies to compliment my TRIO12 😀
Hi sardonx,
Measure your amplifier input and output voltages, measure the resulting SPL. Does the SPL make sense versus the amplifier output voltage?

That's a foolish answer. I often run subs in free air to break them in. I get more than sufficient volume to hear music with 5 to 10 watts. SAme for other drivers (woofs, mid-woofs, full range). Problem is somewhere else.
