BOSS Audio Systems PV3700 5 Channel Car Stereo Amplifier – 3700 High Output, 5 Channel, 2/4 Ohm Stable, Low/High Level Inputs, High/Low Pass Crossover, Full Range, Bridgeable, for Subwoofer

Me gusta súper buena muchas gracias

Very good amplifier. Looks great especially when on at night. I’m not using the bass control on this amplifier. My audio system sounds great. Good value.

Fantástico amplificador para un sonido 5.1 dentro del vehículo si lo combinas con parlantes de la serie Phantom de Boss

I give it a four star. Only really because it's affordable. But first thing I don't really think it's pushing that many watts. I'm thinking more around like a thousand maybe. I don't know I could be wrong but that's just my opinion that's what I feel. I've got mine hooked up to two 6x9 pops and one little 8-in pioneer cheap ass subwoofer and The pops are bridged so I'm only running three speakers off of it and I think it's still not performing all that well. But like I say for the price I don't know if you could beat it. I bought a smaller one because I was installing new stuff in my Jeep and I just had four little six by fives but it was certainly underpowered. I don't know though for the price you know if you're not pushing really big speakers I guess it would be okay. I mean for 170 bucks can you really beat it probably not.

works great

This is a nice looking AMP. it was just too much for my needs. They accepted my return.

Sounded good for 15 minutes until the mounting bracket at one end broke off in the amp nosedived best $171 I've ever spent. What's the point of making something if the metal that you're building it out of is weaker than a freaking twig. Thing is you can say something about it and they say it was your problem. Your fault stop making stuff out of thin pot metal!!!!!

PV3700: I bought this to replace factory system in a 2000 Cadillac DeVille. Now I didn't need massive bass. That was not what I was looking for. This amp is a 5 channel amp. This allows for all 4 door speakers and a sub in the rear deck. Tuned amp for door speakers. I tune via multimeter and set channel 1-4 based on speaker RMS wattage at 3/4 head unit volume. Checked my math and channels 1-4 achieved correct RMS rating. 5 star to this point. Now comes the subwoofer/channel 5. I always tune with bass boost OFF. Tuned for 150 watts and blew an old subwoofer up. Not the amps fault as I didn't remember why this sub was laying around. Bought a new sub that has 250 watt RMS rating. 500 watt Peak. Tuned for 250 watts and worked great. Did a test tune to achieve 500 watt and the amp will not go high enough to get to 500 watt on sub. Tuning test was done with bass boost MAXed out. Channel 5 maxed out at 361 watts. 4 star now. Even though it is not that big of an issue for my goals it is false advertisement as BOSS states 563 watts RMS on 5th channel @4 ohm. When you calculate the amps fuses * voltage, 80*14.4=1,152 watts assuming 100% efficiency. A/B amps top out at 65% efficiency so that makes it 748.8 watts MAX output. That is FAR FAR FAR below the 3700 watts advertised. 3 star. All test tuning was done WITHOUT speakers hooked up as that can be very loud. All Speakers used are 4 ohm speakers. Math is WATTS*OHMS=# SQUARE ROOT OF #= VOLTAGE AC to set amp output.However for my application this amp does the job that I ask it to. If you are replacing a factory amplified system and not really adding much this amp is perfect for that application. You are not going to win competitions. You are not going to have the best sound system in town. But you will have a all-around nice system.Pros: Replacing factory system on budget. Channels 1-4 are as advertised. Sound is very clear on channels 1-4.Cons: Amp is lacking advertised power. Channel 5 RMS maxes out at 64% of advertised power. Total MAX power output is 54% of RMS rated output.
