Bought this amp second hand last week,(thanks to the nice guy) when i play my bass through it, it sound very slightly blown, as if ive got somekind of fx pedal on.The notes arent clear or crisp. It does this wether its played loud or quiet,which makes me think its not blown and its something in the amp which is easily fixed. thanks for any help.

Re: perfect ten bass amp, guitar
Can you use headphones? if so do they sound normal. probably have bad filter caps. 2200uf caps big ones, go bad and lose their capacitance and cant process the low end notes, sounds like a motorboat or ******* out. speaker may have issues as well. get the caps from mouser.com and careful of stored voltage on the capacitors it is deadly....... those caps are less than 2 bucks each.

I have a similar problem with my 2012 civic, I hooked up my 1800w kenwood mp to my 2 12" w6s and 1 song plays and sounds great, the rest of my songs have no bass from the subs, just the car speakers sound normal so I dont know what the hell thats all about. I thought it was a wiring issue but I can play the one song all day and it sounds perfect so any suggestions? thanks in advance
The best way to set up an amp is to start with everything on 0 Turn your gain all the way off, then turn the stereo up as loud as u would normally listen to it. With the stereo on, slowly turn the gain up until it sounds the way you want it. As for the Hz settings, for a sub you should have the crossover set to lpf, and the z knob adjusts what frequency your sub will play. Since you have a 10" sub, I wouldn't put it much below 125, because tens can't produce ultra low bass and it could damage the sub. Hope his helps :)
What main fuses? Fuses in the car electrical system? If so, your amp is too powerful to run through the cars electrical system, you should get a heavy guage wore ran straight from the battery, with its own dedicated fuse placed in-line, ad close to the battery as possible. Wait, is this a bass guitar combo??? Open it up, if there's wax coming from the power supply, thats prolly the culprit. Check for any obviously blown resistors or any short circuits. But most likely, its not gonna be user-servicable.
Sometimes an amplifier's preamp can't handle certain signals/frequencies at a high gain, so they cut out. Bass guitars are especially prone to giving such a strong signal. I bought an older, nonworking bass amp recently and fixed it just to find it had the same problem. Best solution is to put a low ohm resistor at the amps input, but if you turn your guitar down to half volume it'll have the same effect: should prevent it from cutting out.
If you are using a GM-7200 amp, it should sound great. Both the amp and the subs are rated at 800 watts so be careful not to overload the bass by turning them on full power. It is good practice to have a slightly lower watt amp than the subwoofers. If you can power your rear speakers from the amp, that would take away some power to prevent the subs from overloading. Overall, you should get a nice THUMP!!
