With that said, I am on a pretty tight budget so even the "cheap" components put a dent in my wallet, forcing me to make my purchases over time. I am going to post this review under each of the components listed below, so here is what I have built for my old SUV as of 3/1/16: Head Unit: http://www.desertcart.com/BOSS-625UAB-Single-DIN-MECH-LESS-Detachable/dp/B00B65J5B8/ref=sr_1_1?ie=UTF8&qid=1457824650&sr=8-1&keywords=boss+625uab This little unit was received as a gift, but purchased on desertcart. I selected it based on bluetooth connectivity and DIN size. Radio reception is pretty typical. Playback from USB and SD is clunky but acceptable. Bluetooth connectivity for phone calls has a thin, tinny sound at the other end, but of course it sounds really good in the passenger cabin when it comes through all of the speakers. I actually have a philosophical objection to phone calls in a vehicle, so I don't use it. It shines for me as a bluetooth receiver for my media player; no noise or distortion, instant connection once paired, and reliable while connected. I haven't had a bluetooth battle royale to see if a passenger's device will disconnect mine, but maybe someday in the future I will find out for certain. The EQ presets are pretty darned limited, but if you do what I did and pair it with an external equalizer, then everything will be fine for you. It is a very acceptable substitute for the stock Ford radio, so buy with confidence. Equalizer: http://www.desertcart.com/Power-Acoustik-PWM-16-Pre-Amp-Equalizer/dp/B000KHYQGM/ref=sr_1_1?ie=UTF8&qid=1457824732&sr=8-1&keywords=power+acoustik+equalizer This was a bit of a spur-of-the-moment purchase that worked out remarkably well for my system design. It is a powered EQ, so it will boost the signal from your head unit to whatever amplifiers you choose to use. It has four speaker channel outputs (2 RCAs), and one subwoofer output (1 RCA). It has 2 RCA inputs (CD and AUX), and a front panel input for mp3 players/iPods. There is a fader adjustment, 2 separate level controls (one for total level and one for subwoofer), a crossover for the sub (40Hz to 400Hz), in addition to the sub, low, mid and high adjustments. I have not maxed out the unit's level control with my system, but from low to about 3/4 setting provides a substantial change in overall volume. The unit is extrememly solid and durable. The only drawback is that if you are like me and you change music genres frequently, you will fall victim to the eternal joy of constantly fiddling with the dials to get that "perfect" sound for whatever you are currently listening to. Definitely purchase with confidence in the quality you'll receive. First amplifier (door speakers): http://www.desertcart.com/Planet-Audio-AC800-4-800-watts-Amplifier/dp/B00HG6W1VM/ref=sr_1_1?ie=UTF8&qid=1457824825&sr=8-1&keywords=planet+audio+ac800.4 This four channel amp has done exactly what I wanted it for; to power my door speakers. I wanted a good, balanced sound in my vehicle, and in combination with the other components listed here, I acheived something that makes me happy. YMMV. This amplifier provides plenty of juice to the door speakers (also Planet Audio) with enough bells and whistles to make the system sound like someone much more talented than me installed it. This amp doesn't introduce any noise or distortion and it powers my door speakers to volumes that are downright painful, without clipping. It looks very sharp, fits beneath my passenger seat without overheating into protection mode, and gives me way more than enough power for my uses. The only issue that I had was that the holes for mounting were too narrow for the 1/4" driver I was using to drive the self-tapping hex bolts into my floorboards. Also, I would mount it on spacers of some sort, since the cooling vents are located on the bottom-side of the amp. This has been a fantastic purchase for someone like me, with realistic expectations. This is not going to even get you placed in an audio competition, but you won't have any problems hearing your tunes while taking that road trip. 4 door speakers: http://www.desertcart.com/Planet-Audio-TQ623-6-5-Inch-Injection/dp/B003GSLE6W/ref=sr_1_2?s=car&ie=UTF8&qid=1457824210&sr=1-2&keywords=planet+audio+speakers My initial review was a 4 out of 5 stars; I have to revise that to a 5 of 5. My head unit alone did not provide enough power to drive the speakers properly, but in conjunction with the amplifier and equalizer I have listed above, I couldn't be happier. The highs are crisp and clear, the mids are chunky, and the lows are good. I have not yet been able to drive them to clipping, and thanks to my poor hearing I DO crank the volume more than most. These do not compete with Kenwoods, Rockford-Fosgate, or any of the pantheon of quality speakers available; they do beat the absolute daylights out of anything that you will ever be able to find for under $20. Power them with an amp, and enjoy a great sound that won't break the bank but might bruise your eardrums. Second amplifier (subwoofer): http://www.desertcart.com/Planet-Audio-AC1500-1M-1500-watts-Monoblock/dp/B003GSLE2Q/ref=sr_1_1?ie=UTF8&qid=1457824886&sr=8-1&keywords=planet+audio+ac1500.1m+anarchy This is the third Planet Audio component that I have installed, and it works just as well as the previous two components. I am not powering a huge sub setup, just a single 12" DVC (named below) in a ported enclosure and wired to 2ohms; it booms enough for my grumpy old ears and provides a full sound for the music that I love listening to. With all of my components set to 1/2 gain, my setup rattles the frame, trim panels and rearview mirror on my vehicle. That is not suitable for most of the music that I listen to, so I am thankful that this amp comes with a remote level control, and unlike other reviewers, I know that it works properly. I have not driven the sub to the max yet, as I am still working through the break-in period, but I have had it turned up plenty loud enough for my needs and then some. This amp will give you great, noise-free power for any budget build. Subwoofer: DS 18 12" 4ohm DVC with vented enclosure. (my specific model is not listed on desertcart, but I am very pleasantly surprised by the sound and power handling.) So that is the breakdown of the several components that I have used to complete my car audio system. I'm not a "pro" and I'm not going to win any competitions, but I don't have any plans to do so either. I am able to listen to my music loud, with great power and clarity, and it comes on every single time. You CAN build a decent sounding system without breaking the bank. Planet Audio products have more than a few negative reviews, but I would definitely buy their products again. All products will eventually have that one dud that makes it through QC; thankfully I did not receive any of those duds. You also have to balance your needs vs. your expectations; if you absolutely must conform to brand-name recognition, feel free to throw your money around. But you can do the math on your own based off this list, and you won't find much better bang for your buck. Review: Great product / Great value! - I've only had it installed for one day, but so far, this pre-amp / EQ is really cool. I opted to go this route in my '93 Wrangler in lieu of a standard head unit since I only use my iPod and internet radio from my phone when I am driving the vehicle. The vehicle is a weekend toy / trail rig, and I mounted the unit inside the console both to keep it out of the elements and away from would be thieves. Previously, I plugged my phone or ipod directly into my amplifiers. I had no tone control or ability to control the subwoofers seperately from the full range speakers. On a budget? This unit gives you the same kind of control over multiple amplifiers that you would have with a head unit costing 5x the price, and allows for independent control of up to four channels of full range amplification (2 front / 2 rear) plus a subwoofer amplifer. Since I am running one stereo amp for my roll-cage mounted full range speakers, and a seperate mono amp for my subwoofers, this Power Acoustik unit provided the ability to adjust the subwoofer volume independently from the volume of the full range speakers, adjust the bass boost frequency, and provided a 4 band eq / tone controls for the full range speakers as well so I could dial some of the bass out and ultimately get more volume out of the entire system. I have always been wary of the Power Acoustik brand due to my perception of it as a "low end" brand, however am very happy with my purchase here. One thing to note is that this unit does not have a power button. It is intended to be switched by your head unit when you turn the head unit on or off. Since I do not have a traditional head unit in the vehicle, I wired up a toggle switch on the dashboard, which provides "remote turn on" to both the Power Acoustik unit and to both of my amplifiers. The 7 volt pre-amp output provides plenty of signal to the amplifiers. Also, in contrast to what I have read in a couple of other reviews, I do NOT have any sort of hum or 12 volt engine whine in the audio system from this unit. It's as quiet / noise free as it was before when I was running my iPod directly to the amps. I will try to remember to update the review after some time has passed so I can speak to the longevity of the unit. ## Features - 2 selectable balanced inputs & front panel aux input - 4-band, Β±18dB parametric equalizer - Independent volume & fader control - Independent subwoofer output & level control - Variable subwoofer low-pass crossover - 1 Db/Octave Pre-Amp - Isolated Pwm Power Supply - Maximum Output: 8V - Subwoofer Crossover Variable: 30-20 Hz - S/N Ratio: 10 Db @ 1 (A Weighted) ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000KHYQGM | | Best Sellers Rank | #224,561 in Electronics ( See Top 100 in Electronics ) #218 in Car Amplifier Equalizers | | Customer Reviews | 4.4 4.4 out of 5 stars (530) | | Date First Available | January 24, 2004 | | Display Type | LCD | | Expansion | Satellite Radio optional | | Height (inches) | 8 inches | | Is Discontinued By Manufacturer | No | | Item Weight | 1.75 pounds | | Item model number | PWM-16 | | Product Dimensions | 8.75 x 7.75 x 2 inches | | Warranty | 1 year | | Weight | 1.75 Kilograms | | Wireless Remote | No | ## Product Details - **Brand:** Power Acoustik - **Color:** BLACK - **Item Weight:** 1.75 Pounds - **Style:** Compact - **Voltage:** 9 Volts ## Images ![PWM-16 Pre-Amp Equalizer, Standard Packaging - Image 1](https://m.media-amazon.com/images/I/417AgyiJbvL.jpg) ## Available Options This product comes in different **Customer Package Type** options. ## Questions & Answers **Q: is it 1/2 din ? how do you have it mounted ?** A: It is a 1/2 din. Works really good for me as far as the size and functionality **Q: How do you hook this up** A: This is a passive EQ in which it helps controlling your amplifier frequencies. 1. Connect a RCA Jack from your stereo to the left and right to the input of your EQ. 2. If your using a subwoofer amp you will connect the RCA output of the left and right output to your amp, you will now only get low bass frequencies to your amp. 3. Your mid and highs use a RCA jack to connect to the mid and high output, this will control your amplifier for your mids and highs. 4. You have power cable, ground cable, and remote power on to turn the unit on, I hope this helps. **Q: How many amplifiers can it output to? i.e. How many pairs of RCA (etc) jacks does it have? Thanks.** A: You need for sets of RCAs one from the radio to the Eq and 3 amplifiers **Q: what's the return policy on this. mine hasn't worked since irecieved it 3mo ago** A: Its an Amazon product. You should have returned it as soon as you knew it didn't work. I would start a return on it and see if Amazon will allow it. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great little equalizer...buy with confidence. *by S***0 on March 13, 2016* Okay, so I am not a "pro" audio installer it is just a hobby that allows me to putter around, play with solder and copper wire, and hurt my ears.
