Mephis Audio HELP??

[Tacosys 10+ year member]

I currently have a Rockford Power 750S. I am considering going to a Memphis Audio PRD1000.1 only because it is 1 ohm stable. Will I be satisfied with this amp? I plan on using it to power 1 JL 10W7-3. Thanks.

If you're only powering the single 10W7 then why upgrade to an amp purely due to 1 Ohm load stability when you're using a SVC 3 Ohm driver?

It would seem to me that for your particular application 1 Ohm stability would/should be of very little import unless you're planning on making changes to your sub(s) somewhere in the future...

That being said I cannot directly comment on Memphis' Power Reference gear but those that have it seem to enjoy it just fine and I cannot recall hearing/reading an inordinate amount of tales related about equipment failure on that line of gear.

So - all in all you should enjoy it just fine, I would wager. Just bear in mind that the given RMS ratings for that amp are as follows:

300w X 1 @ 4 Ohms

600w X 1 @ 2 Ohms

and

1kW X 1 @ 1 Ohm

Driving an SVC 3 Ohm sub and after factoring in box rise and whatnot I would guess that the Memphis amp you've referenced would give a 10W7 around 350-500w depending on the charging system you have feeding it.

Is that enough to satisfy you?

I am running my W7 at 1.5 ohms. My 750S is only stable down to 2 ohms. Thats my reasoning for wanting to change amps.
