right, the title says it all. ive made a boot install and rewired everything back up. only problem being the lights seem to dim more than they used to. the bass sounds a bit punchier and quieter. before the subs used to really shake the car and sound very smooth, now they can barely be felt.
when the car is parked with engine off or on the subs seem to be fine apart from the punchier sound. the loudness is as it was before. the second i start diving they seem to go a lot quieter.
none of the settings on the headunit have been changed or on the amp itself.
could this be caused by the ground cable not being connected properly. its bolted to the floor of the boot and is very tight. there is a perfect connection there. i was wandering if these problems could be caused by the connection to the amp. this is a somewhat educated guess based on previous experiences.
does anyone have any better ideas as to what could be causing this?
cheers in advance for the help.
