I have 2 cerwin vega 12" subwoofers (400rms ea. and 800watts max ea) I wanna put a fosgate T10001BD amp (1000wattsx1 @1ohm). Do you think it's to much for the subs?

No, but I'd still rather know the pertinent info on your setup, which includes: 

  • What is the combined impedance of the subs going to be?
  • Are the subs going into a vented, sealed or *choke * bandpass?

If you're wiring to 1 ohm and using a vented box, when setting the gain you might have to be listening (and watching) for evidence of over-excursion or bottoming out...instead of listening only for the clipping sound.

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

I am wiring them at 1 ohm and using a vented box, and how can you tell if there is over-excursion or bottoming out or clipping sound.

if i remember correctly bottoming is a snaping sound very loud and noticable.you could easily execeed the thermal limits of those subs . if you could give the model # of the subs. just use good judgement. if they sound like there gonna break back off the volume and or gain.do you plan on upgrading your subs?

They are Vega 124D (DVC). I am very happy with these subs but have been contemplating on upgrading. Maybe JL W6/W7 or maybe a stroker.

do you already have that amp ?  do you like RF products. JL W6 and W7 are SQL type subs . there well rounded but not the best of both worlds.if you like RF products . i would buy that amp . take it easy on those. and upgrade later

This would be the first RF product I would own but I don't have it yet. I just got a new (used) car and just wanted to keep some of my old equipment. Here is my planned set up

Alpine IVA-W205 (head unit)

4 Pioneer 6.5 4 way speakers TS-A1682R (280 watts max each)

2 Alpine 3/8 sps 1005 tweeters (120 watts each max)

T10001BD amp (1000wattsx1 @1ohm)

2 12" Cerwin Vega 124D (DVC) (400 watts RMS each)

Clarion MCD360 3 way x-over

Capasitor (?) any sugestions

Amp for mids (?) any sugestions

The link for the mid amp won't show up. You really think that amp is better than the RF?
