Ok Ok lol this is when i first started to get into sound and was out of town so please don't bash me too much. Didn't do much research just wanted something quick. Well, was in Texas and went to a mexican flea market (I know not the best choice for a amp) Was looking for a cheap 4 channel amp and found a Sharper Vision 4channel high power amplifier model i guess is Sharper-84-4. I tried to google it and search for it by all means, and it's like this amp don't exist! So if anyone can help me find out some info on it I would be extremely happy. Oh yea it's supposed to be a 600mW amp. No don't plan on upgrading for at least 4 months, car needs a new engine This is for my front and rear stage thankyou sry i know a lot to read
Turn it up to its max correct setting. IE, not clipping, or distorting. That will give you the readings of it in your application. You could turn it up all the way for a higher reading, but may damage sub or amp in process.
