Answer:	600 watts
Question:	Why does it say 500 watts on the subwoofer? But you say 600 watts
Answer:	It's neither. Your lucky if you get 200 watts out of it but depends on which input you use and the radios output. I opened mind to see what the audio chips looks like and they are only rated at 150 to 200 watts max.

User questions & answers

Question:	Could I pus these on a monoblock amp? Or would I have to bridge them myself
Answer:	Yes they can be put on mono block, that's what I have set up. Just don't bridge it, it's only 2ohm stable not 1.
Question:	Does anyone have the BOSS 1100 watt riot amp with these? If so how do you like? Does it hit hard
Answer:	I've used it temporarily on the sealed enclosure version of these. BOSS amps are cheap for a reason though. Poor sound quality and it doesn't push anywhere near the 1000 watts these can handle. If you want a cheap amp that actually sounds good I'd recommend the Power Acoustik rzr1-2500d it's not 1000 watts RMS but it'll do 700+ on good electrical & sounds Way better than the boss amp
Question:	anybody had these subs for awhile do they last
Answer:	I have had these subs in the box 4 going on 6 years with a 3000 watt competition massive amp pushing 800 watts RMS bridged making it 200% overpowered I paid $122 for them six years ago and they are still thumping to this day
Question:	Is this just the enclosure or is it the two 12" subwoofers and the enclosure in one deal
Answer:	Everything you see, you get...no speaker wires though...

• Notice: ① Preamplifier needs to work with amplifiers or active devices; ② Not PHONO preamp and can't be used for record players
• Excellent sound performance; No background noise; Warm and soft tube sound; Sound quality enhancement; Pure tube preamplifier; Suitable for all amplifiers and music types

User questions & answers

Question:	I connect my pc to amplifier - the audio output of pc is weak - could it boost it (aoudio aut of pc)much more
Answer:	I don’t have a meter, so I can’t tell you that. However this amp was a vast improvement from the starter Vox amp that I had before. I’m sure if I spent more to buy a set of stacks that would be even better. It never ends.
Question:	Will this improve sound to the AUX port in car stereos
Answer:	There is a slight hiss in these amps, I own the guitar and bass. It's very minimal and does not seem to hiss when its playing, it has to do with the nutube neon light tubes in the amp, it's really cool stuff if you look into it and really creates great tube tone, but hussy when it's just sitting, if you invest in a noise gate pedal, I'd it would help quite a bit
Question:	Does the bass function really work
Answer:	It is not waterproof,, I do have it installed in my 185 searay,,, under my dash and tucked away clear from water,,,, it sounds amazing!! But it is not waterproof....
Question:	What kind of rca cable would i use for the “in” since both ends only have one jack
Answer:	It comes with every thing you need

User questions & answers

Question:	Can i connect this to my Rockville rpg 10 inch bluetooth house speaker
Answer:	Hello customer, thank you for the question, our banTamp tube amp series is designed for electric guitar only, we are also dedicated in producing the bass line for this kind of product, please keep on watching our AITONE store. The combo version in our store is MA-10B, a mini practice amp, just for practice at home but not tube. Please consider twice before place order. Thank you!
Question:	Are these marine grade
Answer:	I think it would probably work with the clean channel but it might not best the best thing. Maybe try an amp made for acoustic guitar. I think it would also depend on the type of pickups your guitar has and if you want it to sound more like an electric guitar. There are products like this: Donner Multi Effect Pedal Chain Alpha Acoustic 3 Guitar Effect Modes Acoustic Preamp, Chorus and Hall Reverb https://www.amazon.com/Donner-Effect-Acoustic-Guitar-Preamp/dp/B07KHVQDBJ/ref=sr_1_13_sspa?keywords=sonicake+for+acoustic&qid=1580694674&sr=8-13-spons&psc=1&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUExOUlGN1JGNEJNNlE1JmVuY3J5cHRlZElkPUEwNTI3NDIxMlJBOVdBT1ZEMklTOCZlbmNyeXB0ZWRBZElkPUEwMDk3MzE1S1dWS0FWRFdMOVVVJndpZGdldE5hbWU9c3BfbXRmJmFjdGlvbj1jbGlja1JlZGlyZWN0JmRvTm90TG9nQ2xpY2s9dHJ1ZQ== I've never tried this myself and you would still need an amp but if you are just recording you could go direct from it I'm sure.
Question:	It looks like it comes with a plug for a quick disconnect. Is it a full quick disconnect or is stuff hardwired into the unit itself
Answer:	Hello customer, This is just amplifier head with no speaker, you need to connect a cabinet to run it, thank you!
Question:	So it has the wiring also
Answer:	Do you know ORANGE amp? This is about this amp, it is a high gain, but if you would like high gain metal, we suggest our ZOMBIE to you, the Mesa Boogie sound, please refer to JOYO ZOMBIE or ZOMBIE XL, these two beasts would fit you better.

DESCRIPTION OF RWK10



The Rockville RWK10 10 AWG (American Wire Gauge) amp kit has the following differences over other amp kits on the market at this price point.

1. Our RCA cables are 100 % copper. These are top of the line RCA cables

2. Better Resistance: The only thing that really matters with wires is the resistance rating. This is a measurement of conductivity and how much signal is loss per foot of wire. Since Rockville wires are made with around 3 times as much copper as any other wire at this price point, these wires had a much better resistance rating which means they will transfer more power to your amps than the other brands.

3. We do not cheat you on the thickness of the wire. These are standard American wire gauge thickness. This is another reason our conductivity is better than anything else at this price point. Other brands in the market place write 10 gauge, but cheat you on the thickness. We are honest about the thickness.

4. The Rockville amplifier installation kits feature a new soft abrasion proof insulating jacket. This rugged PVC outer jacket allows for 100% improved flexibility over standard power cables making them extremely easy to route through your vehicles interior, and it maintains exceptional resistance to grease and oil. The PVC outer jacket can with-stand an extreme temperature range of -40 to 220 degrees F.

The RCA signal transfer cables included in this kit feature blue and silver twisted pair technology in a clear outer jacket insulation skin. Not only do the blue and silver wires look cool but they also provide superior signal transfer with maximum noise suppression. They are 100% copper to provide absolute lossless perfect signal transfer to your receiver. This technology reduces interference, so your audio signal flows clean and pure at all power levels.

The included 7 split loom tube provides protection for your power cable from the typically harsh environment found under the hood of your car.

Audiosavings product experts have tested this amp kit against many leading amp kits on the market and were were impressed not only by the great looks but by the quality of these Rockville installation kits as well. These kits had a lower resistance rating than the other brands we compared and tested them against. What this means is that Rockville manufactures their kits with more copper than other kits at this price point, ultimately providing your amplifiers with better and cleaner DC power, so they work cooler and more efficiently. You will hear the difference a Rockville installation kit will make!



Audiosavings product experts have tested this amp kit against the leading amp kits on the market. Here are the facts from our testing. The resistance per foot of this kit is extremely low compared to any other amp kit in its range. The other amp kits we tested it against had resistance ratings that indicated they were an 8 gauge amp kit. We were more shocked than anyone about these tests, because we used to sell some of those amp kits. (We now will not sell those any more after learning that they are not up to the quality standards of our installers). The conclusion is that Rockville does a great job manufacturing amp kits while other brands are deceiving consumers.

One other last thing worth noting about our kit compared to others. Our kit cosmetically looks the best. It has blue power wire, clear ground wire, and twisted pair RCAs with matching colors. This model includes set of RCA cables.

• Rockville RWK10 10 Gauge 2 Channel Car Amplifier Wiring Installation Kit
• 17 High Grade Twisted Pair of 100% Copper RCA Cable

Product description

Get superior guitar tone and flexibility using this 15-Watt, 1x12 Guitar Combo Tube Amplifier with Celestion Speaker & Spring Reverb from Monoprice! As the title indicates, this guitar amplifier features a 15-watt tube power amplifier and a Celestion brand speaker. It uses three ECC83/12AX7 preamplification tubes and two EL84 power tubes for the amplifier section, plus a Celestion Red Truvox 1215 speaker. The EL84 tube is the tube that powered the Mullard amplifiers favored by the British Invasion bands of the 1960s. It can produce a full output from a relatively small signal and is therefore easily overdriven to produce that distinctive chiming, treble-heavy sound, especially when compared to the 6L6 tubes more commonly used in 1960s era American guitar amps. The amplifier handles frequencies between 80Hz and 10kHz, with hum and noise -75dB below the rated power and 0.5% total harmonic distortion. It includes a Low input and a High input, with the former attenuating the signal by approximately 50% and the latter being easier to overdrive. The cabinet is ported in the rear and features a leather handle, cloth speaker grill, and a cream-colored, textured, synthetic leather exterior with chrome corner guards. The amp features a genuine spring reverb with the ability to enable it remotely using a foot switch. It supports FX send and receive, so you can either connect it to an effects processor or use the send/receive connections as line out and line in connections. Two inputs allow you to select between the full power mode and a 1 watt limited amplification mode for recording or late night practice sessions.

User questions & answers

Question:	Can this preamp connect to my active speakers? or just connnect to power amplifier
Answer:	Hi, This is a stereo preamplifier, you can connect it to the active speakers or power amplifier than to passive speakers.
Question:	I have this hooked up to bookshelf speakers, sounds great, would i hear a noticable difference hooking it to a subwoofer
Answer:	I currently use the Pre-Amp with a powered subwoofer amp, it works just fine. The P1 has frequency response down to 20hz, so adding a subwoofer may be worth your while.
Question:	Can i hook this up to a 2 channel receiver? i have a pioneer sx-10ae
Answer:	Yes you can if your receiver has output/input jacks for the Fosi to be in a "loop". If you do not have input/output jacks then you would be relegated to installing the Fosi to cd player or turntable or whatever component you are trying to acquire a bit of tube sound. I use mine to "soften "a bright metal tweeter in my speakers. Since I have separate components it was easy to install in my case. Also check to see if your receiver has "preamp" in/out jacks. This would also allow you to install the Fosi to have a effect on your receiver as well as any other components you have connected to it. A bit of research on your part will be required.
Question:	Is there a recommended replacement tube
Answer:	I replaced the stock ones with the Riverstone Audio 7-Pin GE JAN 5654W (https://www.amazon.com/gp/product/B01BFJDTW0/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1). They are very nice tubes but do need about 20-25 hours of solid burn-in before they start to "warm up the sound" in my opinion.
