Alright. so last night on my way home, the other sub went up in smoke.
I found a helluva deal on two rockford subs... Some problems though.
I'm headed out to state college this weekend. I refuse to go out to state college without the ability to make my trunk lid rattle. The drive to work was excruciating this morning... All the clear, beautiful sounding treble in the world will not make up for having no bass whatsoever.
Heres my plan. The subs I'm looking at are a pair of rockford fosgate DVC 12"s. Rockford Fosgate® - P212D2
I won't be able to replace my amp until my next paycheck rolls around. I won't be able to build a new box in time either.
#1. My box has displacement of 2 cu. ft... assuming it's matched to the subs since they came as a package. The replacements want 1.75 cu. ft.
My plan as far as this goes is DealWithIt(tm). Pop the new subs in and ignore the fact they might not be perfectly tuned for the box until I can get my hands on some MDF. Any problems with doing this? Assuming the box size specified by the Memphis subs does not take into account the actual displacement of the sub itself.. I'm not too far off... The rockford subs want 1.75' and would get 1.82'.
#2. This is the real problem. My amp: Memphis Car Audio - 150 x 2 Power Reference Amplifier
The rockford subs specify three wiring possibilites. Speakers can handle 200RMS/400Peak.
(1) DVC 2 ohm speaker, running at 4 ohms.
(2) DVC 2 ohm speakers, running at 8 ohms.
(2) DVC 2 ohm speakers, running at 2 ohms.
The memphis amp (pr300.2) Will give me...
150x2 RMS @ 4 ohms
250x2 RMS @ 2 ohms
500x1 RMS @ 4 ohms
So now the problem shows up. How should I run these to avoid more smoke from my trunk? Should I mount up both subs, and only run one for the trip out there until I can get my hands on another amp? Should I run both at 250w with the gain down and pray they don't blow? Can I do anything by bridging down to 1 channel?
Another question about gain, does turning the gain down affect wattage at all? I don't believe it would...
da_bull, since I'm sure you'll be the one to answer all these questions for me, thanks in advance for all the help you've given me as far as car audio goes. I just hope theres a way to figure this one out. If you can give me a solution to this one, I'll go up to that parts car tonight (don't care if it's 2 AM) and get that ABS module out to you tomorrow morning.
