My setup is:
1999 Honda Prelude with
Stock Head-unit (it outperformed the Alpine one I tested so until I find a better one I'm keeping it)
Clarion 9 channel active equalizer with bass control and 6 channel output
Alpine MRP-F-300 (currently set at fifty percent and the stereo maintains its level of crisp sound and high fidelity without overpowering the speakers. I am getting no feed back at all. Crisp clean sound. And even when the volume is at ten my speakers are way too loud for listening but don't distort at all.
Infinity 6.5's with adjustable tweeters in the doors 60 watt rms clean sounding great on the highs with clean lows, great on the bass too.
Alpine Type R 6x9s in the rear deck, 55 watt RMS with 270 max, solid bass and mids, incredibly clear. Awesome when powered by this amp.
Infinity 12" Subwoofer in custom fiberglass box. Great response, awesome when accompanied with the new amp and door speakers. Can't be beat.
14 gauge tightly braided copper wire soldered to each speaker.
Packs a huge power punch
perfectly mounted beneath my passenger seat
more power than I will ever need.
Low power consumption when tested on the multimeter.
Cons: None. Amazing product, Alpine till I die<3
Car can handle it with ease while still being in the charging parameters on the alternator and battery. May end up increasing the 4 gauge wire supplying power to the distributor to 2 gauge or the 1 gauge I have laying around.
-Great power for my smallish car (98 Civic).
-Speaker-level inputs, not used in my case.
-High pass and low pass filters for both channels.
-Perfect size for vehicles with limited space. Mounted mine to the back of the rear seats.
-Never gets hot.
-Nothing in my book. If I really had to pick at it, I would say the screw fasteners are a bit annoying...
I love this amp and I couldn't be happier with my purchase.
Cons- right off the back i could tell the build quality of the amp isnt the greatest and i didnt expect what i had before but the power terminals are awfully small ive seen bigger better ones on cheap no name amps... that is basically my only complaint is the termianls.
I would buy again tho if i needed to
I left the factory radio in, which made a lot more work for me. I had to run speaker level inputs to the amp from the factory radio instead of RCAs way more work. Also instead of running speaker wires to the front doors from the amp ( which would have been very difficult) I ran the power from the amp and spliced into the wires right behind the factory head unit to the front doors. I then cut the wire in the doors and used it to power the crossovers which I screwed to the inside of the door right below the handle. I used the low pass crossover on the amp to cut off the mid to high frequency sound coming from the 6x9s. I used plenty of Dynamat on the front doors and rear deck. I had to lower the gain on the amp all the way to minimum otherwise my factory head unit started distorting at like 20% of its volume level. (it's because the factory unit has such a low voltage signal)
FYI the gain control doesn't affect the amount of power going to your speakers only the signal. Turning it up will only result in signal distortion unless you have a good aftermarket radio. I actually couldn't get the amp to work right away. But i figured out I didn't have a good ground and had to scrape away and use a steel brush on the metal of the car where the ground was to scrape away the paint. ( I grounded it where the seat is bolted to the frame of the car. )
