correct amp?

i want to hook up 2 12" rockford p1s814 into an alpine MRV-F305. the subs are 8ohms. i'm having trouble finding specs on the amp, but i believe the amp handles 4ohms, so if i bridge the subs i should be fine?

does anyone have spec on this amp?

could i hook up my speakers (alpine SPR-57C) into the amp also? it is 4channel.

is the amp 400watts per channel or all the channels bridged?

Thanks.

you could bridge the rear channels of the amp and run the subs wired in parallel. then run the front channels to your SPR-57Cs. that would only give the subs 60 watts rms each though. your amp is 50 rms X4 into 4 ohms. 120 rms bridged X2 into 4 ohms.

so if i wanted to pump the full 300watts into the subs, i should bridge it x2, and get a seperate amp for the speakers.

all regular car amps are rated at 4 ohms, and the class D one are rated at like 1 or 2 ohms. Why are your subs ratd for 8 ohms ?

#1: the guys at the sound shop suggested 8ohms

#2: i was under the empression that 8ohms is "standard" and anything else was unusual.

no, you can't use your amp or your subs to their full potential together. if you bridged the amp, ch 1 and 2 to one sub, 3 and 4 to the other, the amp would only see an 8 ohm load per set. then you would only be pushing 80 watts or so per sub. you really need either a different amp or different subs. those don't work too well together.
if you want to keep the amp, get a pair of subs that can be wired to 4 ohms each.
if you want to keep the subs, get a two channel amp that pushes around 300rms into 4 ohms bridged.

****, that's not good.

8 ohms is the HOME standard ..... 4 ohms is the standard for car speakers. Sounds like you need a new stereo shop.

ah, see that's it. my father was an electrition, and i do electrical stuff now and than, so to me, 8ohms is standard for everything.

the dudes at the sound shop suggested 8ohms, i have no idea why.
