sounds weak?

i had good guys install an 8guage amp kit to my SONY XM-2165GTX   then out to 2 10" SONY XS-L101P5

it sounds bomb bigidity!.   then i decided to install another amp. so i bought a distribution block alont with a 4 guage amp kit.!

 and installed it my self.  wen i played it , it sounded weak. its kicking but not as much as before.. and its on a 4 guage?

so then i took everything apart. and put it back the way it was before.. the way good guys installed it

and it sounds Grrrreeeaatt!!.. wat seems to be the problem?

i already know sonys are good but thats all i could afford sorry!.

yeah . ???? i'm sorry i'm not sure what u are sayin

i did it sounds worse

I'm guesing your amp is bridged right now so its outputting about 400 watts RMS at most. I'm also guesing that your second amp is a 4 channel powering your mids and highs which probobly outputs around 40 to 60 watts X 4. Do your headlights dim when you play your music at night? If so your charging system might not be able to handle all of your amps.

i wired the ground wire for both amps to the same chasis  "same bolt" would that have an effect?

also wen i wired up the 2 amps. only one of the amps was hooked up to subs, the other amp i just left it to see if it works grreeat... but it iddn't so i just took everything down.

also. does the amp kit all have to be the same brand, cuz i had monster amp kit

then i bought the 4 guage amp kit and it was a generic brand name called "c4"

i left the remote wire and the rca wire as the monster cable amp,

all i did was take the 4guage power wire, and the 4 guage ground wire. and a lightning audio distribution block

That might be it.. try this.. Wire it with your 4 gauge. then only have your 2Chanell amp grounded and try it then. Dont worry about the 4 channel yet. If your system rocks then try putting the 4 channel in another ground.. Make sure to sand out any paint chips..lol.
