Ok I recently got an MTX Blue Thunder pro-752 amp from a friend for $40.00 what I want to know is will it be good enough to drive my front speakers???(they will be aftermarket of course)

I don't know too much about this amp,,but is it a 2 channel???
and will it be good for what I already have???
Pioneer headunit,,RF amp.,,,RF 12"sub in single bandpass....

Well you have powering your sub that RF amp...now if you don't know really much about that new MTX amp of yours, check their site. I wouldn't know if it is a 2 cha or 4 cha. It will do you good if the mtx amp is 2cha 200watt total for your fronts. But what about the rear? If the mtx amp is 4cha then you can power your 4speakers...that's if only the mtx amp has enough power. a 4x100 would be good.

That would be too much power. 100 watts to each speaker is a bit much. Check the power rating for the speakers. You don't wanna blow them. I am sure you could get speakers that can handle that much. I only have 35 watts going to each of my front aftermarket speakers.

many dumb speakers "say" that they can handle 200watts which is bull...their rms go up to only 100peak. 35 is too low...but speakers vary. You would rather have more power than just enough power.

Yeah it depends on what the speakers handle RMS wise but even if the amp was 100x2 or something like that you could just turn the gain down on it to fit your speakers perfect. But yeah most decent speakers only handle like 25-80RMS wattage.

I wish i had some more cash so i can get that nice 4 channel PPI for my mids....*drool* Maybe if i sell my soul

i'm pretty sure it's a 2-channel amp and I believe it's 280 watts...now you can't run all the front speakers of a 2-channel amp??

ok here's the exact info i got of their website....
PRO75X2
Advanced Computerized Protection Circuitry - improved protection circuitry, for fewer failures. When the protection circuit is activated, the amp will turn off.
Larger Terminal Blocks - all models can accept up to 4 gauge wire (i.e. more current capability)
Larger Heatsink - each model "grew up" by 1 to 2 inches with substantially more mass. Greater cooling capabilities, and longer initial time to thermal.
Larger Output MOSFETS And Larger Power Supply MOSFETS - provide better power stability and improved reliability.
New Thermal Pads Under MOSFETS - because silicon grease, formerly used under the MOSFETS, broke down over time and spilled out onto circuit board, we replaced it with polymer thermal pads that offer better transfer of heat from MOSFET to the heatsink. Over time, the polymer actually fills in the pores, creating an even tighter seal. This improvement offers a greater degree of consistency in manufacture for better product reliability.
Improved ISO-FEET - upgraded to a more pliable nylon material, for improved durability and flexibility.
8-Volt RMS Input - this Large Signal capability allows better integration with high voltage output source units, increased dynamic range and better Signal-to-Noise ratio in the system.
Continuously Variable Crossover - this allows the user to adjust the crossover frequency from 40Hz to 175Hz with a high or low pass configuration, including adjustable crossover slope from 12db - 18db/Octave.
Advanced PCB Design Technology - a new FLOOD technique in circuit board design allows us to truly "flood" the circuit board with copper for substantially higher current capability, lower distortion and increased reliability.
Thermal Reliefs - New "star pattern thermal reliefs" improve solder connections and increase reliability.
Individual Gain Controls For Left/Right Channels - for better tracking and to make it easier to center up the soundstage (a critical element in the competition circuit).
Reverse Outputs - when the user selects the highpass setting on the crossover, a complimentary lowpass signal is passed through the RCA outputs, and vice-versa. Crossover frequency of the RCA outputs is determined by the frequency setting on the crossover. This makes it much easier to design multi-amplifier systems.

You will want to have this done:

75 watts x 2 into a 2 ohm load with less than 0.1% THD+N

But make sure you lower your 280watts to your front speakers...lower it with the nob or switch. To be on the save side...75 is good.

so at least I can use this then,,,cool


so now what do i have to do to run all the speakers to it do i have to run both fronts into the left and the rear decks into right say,,,is that sounding about right???

Thanks for any info guys and gals I'm far from the stereo expert

Buy my componets I still have man


Infinity 6 3/4 Kappa Componets. $299 new at crutchfield.....

I still have rears too.. $150

$230 shipped to your door, only 2-3 months old and have the wood spacers I made to let them fit without hitting the glass (a must int he sentra for any aftermarket speaker).

SentraSty, I wouldn't know how to connect the wires from speaker to amp. I'm not the expert either, I know Chrissy knows more than I do...she can answer your Q.

Sorry

btw, what's your aol or aim SN SentraSty?

UMM, ignore power ratings! I have repeadetly found that speakers LOVE power. Granted there is a point where you CAN have too much, but that's typically not what blows speakers. Distortion and improper crossover settings are what kills speaks. I have about 225 watts going to each side of my front stage. The tweets and mid's are getting over 100 watts each! They love it. Why, becuase it's free of distortion and they are crossed over properly! Also, this allows you to keep the gain to a minimum (provided your input voltage is setup correctly), this provides much needed headroom! Speakers love power, just clean power!
