alrights, i have my system installed exactly in the DIY.

i just need help tuning it

it thumps alrights but its not thumping as hard. when i tuned it following the instructions i turn up the volume to how much i usually play. it thumps hard then the sub just stop thumping but the amp is still on then i turn off the car and turn it back on and it doesnt do that no more. i tried messing around iwth the settings a few times. still happens

the ground is near the spare tire. its where the other ground wires are i didnt want to drill a hold so i took off the bolt where the other ground wire was at and placed mines there with the others.


here are pictures of my wiring

very messy and im going to tape up the wires just need to go get some.

 

just an idea...
Amp's have protection circuits. if you exceed the current allowed, the amp could go into a 'safe' mode. if so cycle the power on the amp, and don't thump as hard next time and it should be fine. if the subs are paralleled, then the impedance the amp sees could be too low for the volume you want.

 

i figured it out. the amp goes into safe mode i figured that out just now also. thanks i will let you guys know updates after my sister wakes up =X
