In my old Accord I had a 4 channel amp powering a set of alpine type X comps in the front, as well as my RE SE 12" sub in a ported box. This set-up absolutely slammed, and I rarely had the subwoofer levels turned past 1 or 2 because the bass was so powerful.

Now I have a new car and I installed the amp and it is just powering the sub alone. The gain is turned up almost to the max, yet the sub hits so softly that you can't even tell it's on at subwoofer level 0. The sound is also sloppy.

Why is the sub so much weaker now? I have it in a sealed box now rather than the old ported one, and I know this will probably make a difference, but it feels so weak. I feel like my excellent sub is being wasted. What happened to the gobs of bass that I felt with my old set up?

Help me

 

how is it wired up?

 

I had it professionally, installed, but what do you mean by that?

 

how is the sub wired to the amp. bridged to one channel?

 

I have no idea. Is there a specific way it should be wired? I'm gonna go back and check with them in a day or two.

 

troubleshooting over the internet can be a lot like shooting fish in a barrel....

take it back to the shop that installed it and ask WTF......

 

If its as you described:
“yet the sub hits so softly that you can't even tell it's on at subwoofer level 0. The sound is also sloppy”

then there is a fault especially if it was professionally done
ported vs sealed there will be a difference but not that much
2 difference cars there will be a difference too but also not that much.

How much does the sub move put a test disk in and do a frequency sweep and see if not just the music that’s not in the resonance range

 

Same head unit?

 

Check your cable I had a cable that wasn’t grounded properly and you know when you turn it up loud you can just here it and you get a slight humm

yes what he said what headunit? is it the same setup as previous?
