## Description

SS8P Description: The SS8P is an all-in-one solution that provides great sound bass for your vehicle without taking up much space. This sub-enclosure is only 2.8 inches thick and fits easily under your seat. Built-in amplifier makes installation and wiring clean and easy. This is a true all-in-one subwoofer solution. The subwoofer is built into the enclosure, and the finest amplifiers are built in. We focused on making installation easier, so we designed this unit with you in mind. We have added a high level of input so you can install it on aftermarket or factory system. High level input allows installation even without preamp output. Smart turn-on circuit detects audio signals and turns on the amplifier. When you turn off the music signal, the amplifier built in in this subwoofer system will automatically turn off. What we did to make installation quick and easy is to place all the input and output on one side. This makes wiring clean and easy. Our competitor models are more difficult to install. The SS8P features 400 watts of peak power and 100 watts of RMS. It has great controls so you can adjust the sound to your preference. Volume and subsonic filter level control filters out really low frequencies that are not heard by human ears. It also features a low pass crossover filter, phase control, input sensitivity, and bass boost. It comes with a remote bass knob and mounting hardware, but the best part of our model is the sound. Slim, but sounds like a full size subwoofer. We offer 90 days money back guarantee if you are not satisfied. If you don't like the sound, we will send you a pre-paid label and we will refund you for a full refund! RWK10 Description: The Rockville RWK10 10 AWG (American Wire Gauge) Amplifier Kit has the following differences compared to other amplifier kits available in this price range. 1. Our RCA cables are made of 100% copper. Premium RCA cables. 2. Excellent Resistance: The only resistance rating is really important for wire. This is the conductivity and the amount of loss signal per foot of wire. Rockville wire is made of about three times the copper of other wires, so this wire is rated much higher and transmits more power to the amplifier than other brands. 3. Don't be fooled by the wire thickness. These are standard American wire gauge thickness. This is another reason why our conductivity is superior to anything else in this price range. Other brands on the market say 10 gauge, but they are thick enough to be overpowered. Thickness is honest.

## Questions & Answers

**Q: is everything in the box needed for Installation?**
A: Yes, with the accompanying Amp Kit. Its complete along with rubber insulation you gave to attach yourself. I would suggest electrical tape, wire strippers, and a pair of terminal/electrical pliers  (I apologize if you are already aware.).

**Q: Has anyone added a second sub to their system?**
A: Yes. I used RCA splitters and installed two in my Mitsubishi Montero. Sounds amazing and have been going strong for 3 years. I tried to split the remote control using a telephone line splitter but got weird feedback when I tried to do that, so I just went without the remote control.

**Q: How difficult is this to install?**
A: It's easy to install if you understand stereo systems and how to run the wires. The hardest part is getting to your stereo. Not sure if you have experience or not installing systems. If you do, its easy.

**Q: If I got splitters for both the rca and remote control (telephone jack), can I install one sub under each of the front seat?**
A: Yes. I split my rca signal and installed 2 of the speakers.
