WICK3DxGATA Posted March 23, 2012 Report Posted March 23, 2012 (edited) okay so i got some new subs and amp cheap i couldnt pass up the deal. but i need help on how i should wire them. so i got 2 of the new p3 12s http://www.rockfordf...x?itemid=120421 and this amp http://www.rockfordf...x?itemid=116138 the subs will be in a custom built down fire ported enclosure for underneath the back seat of my silverado. its not a regular box before any one says i need a bigger box. this box is huge about 1.8 cubic feet for each side. so if i could just get some feedback on the best way to wires these it would really help.

WICK3DxGATA Posted March 23, 2012 Author Report Posted March 23, 2012 sorry they are 2 ohm subs Quote 99 Gmc sierra extended cab front speakers: DB drive 6.5 back speakers: DB drive 6.5 amp: none right not subs: none right now Future waiting to get my 2 skar vvw 8s installed
Toby Ratcliffe Posted March 23, 2012 Report Posted March 23, 2012 well unfortunately with two dual 2 ohms subs your wiring options are limited to .5 ohm, 2 ohms, or 8 ohms. Taking into account impedance rise you might be able to get away with .5 ohms on that amp. If it goes into protect, you will need to wire it to 2 ohms. to get .5 ohms, wire it in series, by connecting all of the positives together and the negative together, and then to the amp. to get 2 ohms, you need to wire it in a series parallel configuration by jumping a positive and negative on each sub, and then connecting the remaining positive, and negatives to the amp output.

WICK3DxGATA Posted March 23, 2012 Author Report Posted March 23, 2012 well would it be better if i traded the two ohms in to get the 4 ohms?

WICK3DxGATA Posted March 23, 2012 Author Report Posted March 23, 2012 (edited) i also have this amp laying around would it be better to use with the 2 ohm subs its the 1200 mono block http://www.mtx.com/m...fiers/show.html Edited March 23, 2012 by WICK3DxGATA Quote 99 Gmc sierra extended cab front speakers: DB drive 6.5 back speakers: DB drive 6.5 amp: none right not subs: none right now Future waiting to get my 2 skar vvw 8s installed
Joe X Posted March 23, 2012 Report Posted March 23, 2012 i also have this amp laying around would it be better to use with the 2 ohm subs its the 1200 mono block http://www.mtx.com/m...fiers/show.html That would give 400W RMS to each sub at 2 Ohm. Quote
CleanSierra Posted March 23, 2012 Report Posted March 23, 2012 well would it be better if i traded the two ohms in to get the 4 ohms? Yes, trade them in and get dual 4s. DONNNNNNT wire that amp at .5 ohms, it'll go into protect. Dual 4s will wire for a final ohm load of 1 ohm and will get the most power of that amp. Quote Im not the one you want to try to troll. Just a fyi for you.
Toby Ratcliffe Posted March 23, 2012 Report Posted March 23, 2012 If you could trade them in for dual 4s, that is the route I would go as well. Quote
WICK3DxGATA Posted March 23, 2012 Author Report Posted March 23, 2012 okay so if i trade them in for the 4 ohms how would i wire them?
