Need Help!

[StraightUp 10+ year member]

Hello everyone,

I'm hoping I can figure out this problem I have with my audio setup. I would appreciate any help I can get as this is a big pain. This is kind of a long story but I will try to make it short, if you need me to clear anything up, please ask. On a side note I'm not very mechanicaly/electronicaly/audio inclined. lol

So here's the deal:

My buddy and I have basically the same setup. We have mazda6s with ported boxes for 2 10's. We both have Rockford Fosgate P3 4ohms. But his are shallow mounts and mine are the regular subs. So I'm expecting mine to hit harder, but his are way **** louder. Mine aren't even close, it's ridiculous. On the amps he has a older RF 2 channel 600 watt amp, and I have a SSL 2 channel 1000 watt. Your probably thinking it's the amp, but we switched amps tonight to test, and mine still is not living up to my expectations. What could it possibly be??? I'm starting to think there is something wrong with my subs.

Definitely a headache. Thanks for the help

his has less power handling, so therefore his subs are probably seeing power closer to there specs, whereas your amp isnt probably pushing out the amount of power that the woofers are actually asking for (RMS). that would make more sense to me

Any ideas on what amp I should get? Thanks

Get new subs

Does he have his shallows in a box designed for shallows or are his subs in a box for normal subs?

 

[StraightUp 10+ year member]

Man I will be pissed if its the subs, I got them from sonic, what would be wrong with them? The box is for normal subs

How are your subs wired?

 

[pr-festiva 10+ year member]

are the box's facing the same way?

 

[StraightUp 10+ year member]

Series parallel and yes they r facing the same way

 

[IonRL205 10+ year member]

What's the exact model number of your amp?

 

[StraightUp 10+ year member]

EV2.1000

Series parallel and yes they r facing the same way

2-D4 in Series they will give you 16 ohm

2-D4 in Parallel they will give you 1 ohm

big difference...

im just taking a stab here but i think he ment that he wired his coils in series to 8 ohm then in parallel to a 4 ohm load and bridged his amp. Check all your wiring one sub may be out of phase.At least your going about trouble shooting the right way by eliminating possible culprits. check the amp settings too
