Cody, wouldn't that be too much power. The 551s is listed as 275 x 2 bridged at 4 ohms.

Maybe a less powerful amp for the back set would be a good idea, with the 551 to the front set?

Thanks, I could've bought a set of pce-216 for the same price as the MM6 but a little too late now. Still struggling with the amp situation, hate to underpower such nice speakers but I would have...

Thanks Cody

Thanks for the advice. You're right but I am powering 4 speakers which would make it 4 x 75 at 4ohms. Still ok?

I have just made a purchase and am second guessing myself after reading some posts below.

Running off an Eclipse 8441 deck in a Yukon I already have amp running to a single 12" sub. I just...

Thanks for the advice. I am new at this.....what is clipping and how do you set the gain so appropriately. Sorry fo the newbie question.

Thats the plan. Using a 2 ohm L7 I should be able to get 550rms from the amp with the speakers rated at 750, I will be a little underpowered but not too bad, right?

The box was 0.65cu. It must be because they are underpowered as you suggested. I have decided to go with a single L7 12". It is a little underpowered, but I hooked up a demo at a local store and...

subs are infinity perfect 10.1s and the amp is a fosgate 550s. i have decided to send them back and go with a single 12. i know i am all over the board but i get a different answer every time i...

I went to a local place with lots of experience. We hooked up the amp to another box/sub and it sounded fine. Either the truck style box is a bad match for the subs or the subs are too...

Why do you say 50%. I thought the 551 powering the 2ohm L7 would put out 550rms and it is rated for 750. You're probably right but could you explain. Also, I heard it would be more efficient in a...

Please help me decide on a sub or subs. Already have 4 MM6 components in the doors. The amp for the sub/subs is installed and is a fosgate 551s. I listen to a semi-wide range of music but wouldn't...

Just hooked up two tens in sealed boxes with appropriate amp/sub match but when they hit they have an empty vibration. I do not think it is the subs or box after trouble shooting. The amp is a...

This is the recommended size, I just wasn't sure if the sound from a truck style box is inferior?

Are 4 components (MM6), one in each door and 2 10" subs in the back ok for an suv or shoud the rear door have different speakers?

I have a yukon but need my back floor space for equipment. I ordered the truck style box instead of normal square but both are .65cu. The speakers are infinity 10.1d 10" subs, is this ok or should...
