| Wow, there could be so many issues...
Are your subs wired for a load appropriate for the amp? It appears to run at 2 ohms, is this correct? 2 4 ohm subs would need to be wired in parallel to achieve 2 ohms.
Did you start out by turning your amp's gains all the way down? How about your HU, is your loudness switch on or off, start out by having it off and everything set to flat on your eq.
Are your subs installed in a box, were they in the same box when they sounded good in your friends car? Was it sealed and you've got a ported box now? |
