Need help!!! Not hitting like it should

[pdxtls6875]

I am brand new on here, and have limited experience in car audio (the technical stuff).

I currently have a 2003 Acura TL-S with:
1 - Blue top Optima up front
1 - Pioneer DEH-P7900BT
1 - SHURiKEN - SK-BT20 in the back
3 - 12" Phoenix Gold RSdC124 - in a custom sealed box. All one chamber and approx 3cf internal air space
1 - Ti2500.1
1 - Ti600.4
1 - pair Morel Tempo 6 separates in the front and stock speakers in the rear doors.

It is a work in progress as you can see. But my biggest question is... Why the hell doesn't the bass hit like i thought it would?

any ideas? Suggestions? modifications? wiring?


See the pics below to see my trunk in progress....

how are the subs wired?

[pdxtls6875]

They are wired in series parallel. It's like they aren't getting enough power.
3 - 12" Dual 4ohm

[pdxtls6875]

Or maybe ditch the 3 subs and go with 2? one? I am open to any ideas. I just want the hardest hit out of my 2500.1

what is the impedence the amp is supposed to be seeing then? And have you tested it with a meter to be sure its wired right? Its easy to mix up and if the amp isn't putting enough power out I have to wonder how the subs are wired.

They're not, with 3 of the D4's wired as you stated you're getting a 2.67ohm load and each sub is rated at 600wrms - 1200 peak. The 2500.1 makes the most power at a 1ohm load, so your not getting anywhere near the power you need, if they were D2's it would be a different story. Don't wire the subs in parallel / parallel or you'll see a .067ohm load which will shut the amp down due to too low of a load. Pictures below from JL's website.

What would be a good subwoofer match-up to my 2500.1? I want it to hit!

[ttocs]

disconnect one sub and run 2 subs with all 4 coils in parallel. Or else trade for SVC subs and you can get it down closer to 1 ohm.

If you wanna stay with the 3 - 12" set up in PG you could go with the new TI212D2 subs, should be about the same size as the RSDC's and wired per the pictures I posted would give you a 1.33ohm load which would be just the right power for them . If ur located in Portland, check out Car Stereo City or Outrageous Audio as they're PG dealers ...if you wanna stay usin' PG 12's. ")

If you are in Portland I know someone that mat be interested in 2 of the subs depending on price.

make sure all the subs are wired in the same phase also. if 1 was backwards it would cause cancellation.

even on 200rms each, rsd's still rail pretty good

good to see another portlander!
