I have been a big fan of aftermarket car audio equipment ever since I bought my first car, and have never looked back since. The standard manufacturers' equipment does a job, but I wanted something that would give me an experience and not just a sound. I listen to the radio in the car, but also CD's and mp3. As the sound going into my system is of a high quality, I wanted the speakers to be able to emit sound at a high grade also. In order to do this I install aftermarket speakers which are far superior to the standard units supplied in the majority of cars these days, and power them via the Pioneer GM 6300F Amplifier. The GM 6300F is built into my boot install and as it is reasonably compact it can easily be hidden away if you so desire. The looks of this Pioneer amp are also a positive, with clean lines and simple branding, the colour and design wont look out of place however it is located. I chose Pioneer because I have owned a lot of car audio equipment from them in the past and I like their simple styling. Priced at around £120 it isn't the cheapest amp around, but it does offer the most precised output to my speakers that I have experienced so far. This is a 4-channel amplifier, delivering a maximum output of 600watts. This means you have an option to either have two speakers running 2 x 300watts, or use 4-channels and have four speakers amplified to 150watts each. The signal to noise ratio is 95db. This isn't great compared to some units, but it does hold its own against similarly priced amplifiers and will be able to feed even the best speakers around, so power isn't an issue. The weight of the amplifier is something that did surprise me. Although it is quite a compact unit I feel that nearly 4kg for such a small sized amp was rather a lot, though I ensure it is securely fixed down in my boot! As I highlighted earlier, though, looks are not fussy at all and Pioneer have kept things as plain as possible without being boring. One concern I do have is that the casing of the amplifier is a little bit light and flimsy. I can imagine if you dropped it once or twice accidently it could indeed cause more than just a bit of cosmetic damage. I wouldn't say it looks cheap or tacky, but case construction could be better. One thing I particularly like is that the set-up is so simple. The RCA connections are not the best, and could no way be described as robust. This is another area Pioneer have disappointed on, though I don't plan on adjusting the connections anytime soon, so I don't see this as a major problem to myself. Instructions are included for how to set the amplifier up to a set of speakers and aswell as connecting the unit to the speakers you must also run a set of wires to the head-unit obviously. Power is the final part of the jigsaw and as I already had a power cable running directly from the battery this wasn't an issue. The final point to note is that you must ensure the power element is amped, as failure to do this could be very expensive indeed. The Pioneer GM 6300F does have its positive points, but there are also some things that I would have hoped Pioneer had perfected by now. All things considered I have to recommend this amplifier, though it isn't an absolute recommendation and with its flaws it won't last a lifetime.
This is a review of the Pioneer GM 6300F, I bought this amp for my Alfa 159 after purchasing an in car amp for my brother, hearing the sound put out by his amp I was instantly jelous and decided to bite the bullet and Purchase this Pionner car amp. This is alot easier to set up than the main rivals. It comes with a simple instruction manual and the needed cables etc. It can be fed in to two speakers at 150 wats RMS (300 watts max) or in to four speakers at 60 watts RMS (120 watt max). I opted to plug this in to two seperate speakers as my car alreadt boasts an 8 speaker system. The sound out of this is unreal, the quality is unmatched and I have to say I preffer this model to my brothers (Sony, see my review!). I do tend to opt for Pioneer when it comes to in car systems but I that is simple because in the past they have never let me down. All in all this a great buy.
Sometimes you just need a bit more and where car audio is concerned, that can only mean one thing - an amplifer. As I seem to spend a lot of time in my car, good audio is essential. With my experiences with Pioneer, they were always going to be one of my first choices for fulfilling my requirements. And so I have the Pioneer GM 6300F. The four channel unit can deliver a maximum of 600 watts across your speakers with a signal to noise ratio of 95dB. You can set that up as either 2 x 300 watts or 4 x 150 watts. Frequency response is measured at 10Hz - 50Hz with a total harmonic distortion of less than .01%. It is a really compact unit measuring 300mm x 60mm x 334mm so fitting it under a front seat is possible although at 3.9kg it will need to be secured well to avoid problems in accidents. It is fairly economical in terms of power with a maximum consumption of 35amps. It is durable and well built and in the time I have owned it have had no problems. It does not overheat, no noise or vibrations and it has not caused any electrical problems. Perhaps one of its best selling points is that it is not specific to Pioneer head units, so if like me you were happy with what you have or you are just upgrading piece by piece, then the GM-6300F can be used without the need for buying add on adapters. But as a note of caution, the RCA connections can be a little flimsy. The unit itself can be described as minimalist in terms of its' shell. It has a classy metal coloured in a mostly matt black but with a brushed steel panel at its' centre. When it is switched on, a neon blue light, located on the left glows. You can pick one of these up from car audi centre website for £126.99 and it comes with a comprehensive users manual and a 1 year manufacturers guarantee as well as all the features you would need for a total in car audio experience delivering a crystal clear sound to put you in house stereo to shame!!
The 4-channel GM-6300F delivers a whopping 600 watts max (60 watts x 4 or 150 watts x 2 at 4 ohms; 75 watts x 4 at 2 ohms) - plenty of juice to power your high-quality speakers. It's also got built-in 4-channel crossovers. Speaker level inputs for easy connection to an OEM headunit. Oversized power terminals. And a wide input level of 400mV to 6.5V.
