If you can't sell her, I will take care of her for you... I have a huge driveway and wash my cars every sunday . But yea I totally understand, I hate to let cars sit.

The slope is measured in db/hz... The sharper the slope, the faster the cut off between lows and highs... Your deck uses a single highpass front and another high pass rear. And one low pass on the sub out. As far as the eq is concerned, it shouldn't make a huge difference, you are just trying to get it to a point where it sounds best to you... You aren't going to compete in SQ so do what sounds best to you and your ears, the guidelines I set forth were the ones given to me by an Iasca pro who takes sound quality to a whole new level. The biggest thing lesson I learned is use a notebook and write down your settings before you change them, and what you changed them to. That way you can look back and adjust more effectively in the future.

Your High Pass crossovers etc are in your head unit, you already listed that you found them in a previous post... If your speakers already have passive crossovers than you don't need to worry about it. A rule of thumb for EQ is never move a band more than 2 settings lower than the next one... Generally speaking SQ competitors don't ever move a band up, but only down because up = artificial amplification. You shouldn't need many features with passive crossovers and factory speakers.

Also tuning by ear is far from guessing. There is a reason why pro's do it by ear.

The method you listed with a chart has as many flaws as tuning by ear. Clipping with a tone is a pretty distinct change in "pitch" probably the wrong wording. I have used ~4000 watts of amp on 2 800 watt subs without an issue tuning by ear.

Trust me J, I would love that car.

F-bodies (Camaro and Firebird)

Would love the car, definitely will be out of my budget come spring. I <3 camaros, but will most likely pick up a gtp b/c they are dirt cheap around here

More info on it? Would be nice to keep it in the SSA family

The sundown SA-8 is 89$ if i remember correctly

What impedance are you looking to run?

Congrats Mark. If you need anything let us know... And you know our Mod team and Aaron will keep the site running well, so take your time.

Take a tone, say 50 hz and turn your gain up slowly, as soon as you hear the sound change (distort) back the gain down slightly.... Your volume on your headunit should be at ~3/4 (that's about where the rca outputs start to clip)

Oscilloscope was used to set gains and prevent clipping.. My ears and that of a fellow SQ pro competitor were used to set the time alignment and eq. I used the high pass filters instead of a passive crossover. The main settings to change are the high pass/low pass filters. I would start out with high pass at 80 hz and low pass at 90 hz.. That head unit can't support a tweeter high pass, but it shouldn't be an issue with stock speakers.

So a couple quick questions and I will help where I can... What speakers are amplified. Do your front speakers have a built in crossover? Do your amps have crossovers and are they set? Yes your headunit has a lot of features that SQ nuts will love and many things that you will never need. I used to own an sq car and an sq headunit so I will help the best I can.

***Copied From Crutchfield*** Audio Section 24 Bit D/A Converter: The Kenwood Excelon KDC-X995 utilizes a 24-bit digital to analog converter for superior CD sound quality. MOSFET Amplifier: The Kenwood Excelon KDC-X995 is equipped with a MOSFET amplifier. Compared to conventional power supplies, the MOSFET amplification circuit is smaller and more efficient, and it delivers increased power with less distortion and absolutely zero on/off switching noise. More power means louder and cleaner music at higher volumes because you're not pushing the limits of the amplification circuit. The power output specs for the KDC-X995 are as follows: Full Bandwidth Power: 22 watts RMS x 4 channels (at 4 ohms, 20-20kHz, 1% THD) Maximum Output Power: 50 watts x 4 channels 6ch/4V Preamp Outputs: The KDC-X995 features front, rear and subwoofer 4-volt preamp outputs. The front and rear speaker preamp outputs are balance and fade adjustable. The subwoofer preamp output is non-fading. The front, rear, and subwoofer preamp outputs are fixed to the rear chassis of the head unit. Note: You can turn the KDC-X995's built-in amplifier off to improve the quality of the sound from the head unit's preamp outputs. Front & Rear High-Pass Filter: The KDC-X995 features an independent High-Pass Crossover for the front & rear channels when your front & rear speakers are connected by the unit's speaker-outputs or preamp-outputs. You can adjust the high-pass crossover from "Through", 30, 40, 60, 80, 90 100, 120, 150, 180, 220, or 250Hz. The "Through" selection is a full-range setting. This feature is very helpful when you have smaller-type speakers in the front and larger-type speakers installed in the rear of the vehicle. You can also select the high-pass crossover slope ( for the front & rear channels. Subwoofer Controls: The Kenwood Excelon KDC-X995 provides the following subwoofer preamp output controls. Low-Pass Filter: The receiver features a built-in Low Pass Filter control for the unit's subwoofer preamp output. You can select from 30, 50, 60, 90, 80, 100, 120, 150, 180, 220, 250Hz, or "Through". The "Through" setting allows your external amplifier's crossover network to do all the filtering for your subwoofer. Subwoofer Phase: You can adjust the phase of the subwoofer output between 180-degrees (Reverse) or 0-degrees (Normal). Subwoofer Level: You can independently control the subwoofer preamp output level from the CD receiver. You select levels between -15 to +15. Rotary Volume Control: The CD receiver uses a 7-way rotary volume control that increases and decreases the volume of the stereo from 0 to 35. The rotary knob also controls other audio settings such as Balance, Fader, Bass, Mid, Treble and preset EQ settings. In addition, the rotary knob allows you to scroll through and select your music tracks when the Music Search function is activated. Volume Offset: The level of each source may be independently adjusted to prevent radical leaps in output volume when switching from one source to another. The available settings range from -8 to 0. Supreme+ Setting: When MP3, WMA, and AAC files encoded at a low bit rate (less than 96 kbps, 44.1k, 48kHz) are played, the Supreme+ Setting function restores their high frequencies so the sound quality is closer to files encoded at a high bit rate. The processing is optimized for the compression format and the bit rate used. When the Supreme+ Setting is Off, the unit plays the original sound stored in the audio file. Sound Excellence DSP: In order to optimize the sound quality, you can use the Sound Excellence DSP to set the type of vehicle and speaker sizes, locations, distances and x-over points. The DSP settings include the following: Car Type: Choose from Compact, Full Size Car, Station Wagon, Mini Van, SUV, Mini Van (Long), or Off Speaker Setting: The speaker X'over is automatically set when the position and size of each speaker are select from the following items. Front: Location (Door, On Dash, or Under Dash); Size: (6-1/2", 6-3/4", 7", 4"x6", 5"x7", 6"x8", 6"x9", 7"x10", OEM, 4", or 5"); Tweeter (None or Use) Rear: Location (Door, Rear Deck, 2nd Row or 3rd Row; Size (6-1/2", 6-3/4", 7", 4"x6", 5"x7", 6"x8", 6"x9", 7"x10", OEM, 4", or 5") Subwoofer: Size (15", 12", 10", 6-1/2", 8", or None) Digital Time Alignment (DTA): Choose from 0.00 to 14.44 feet for the Front pair of speakers, Rear pair of speakers, and Subwoofer distances in reference to the distance between your listening positioning and the locations of the particular speakers. X'Over: The Kenwood Excelon head unit provides independent high-pass crossovers for the unit's front and rear speaker/preamp outputs, as well as a subwoofer low-pass crossover. Front High Pass Filter: Frequency (30, 40, 50, 60, 70, 80,90, 100, 120, 150, 180, 220, or 250Hz); Slope (-12, -18, or -24 dB per octave); or you can also select full-range Rear High Pass Filter: Frequency (30, 40, 50, 60, 70, 80, 90, 100, 120, 150, 180, 220, or 250Hz); Slope (-12, -18, or -24 dB per octave); you can also select full-range Subwoofer Low Pass Filter: Frequency (30, 40, 50, 60, 70, 80, 90, 100, 120, 150, 180, 220, or 250 Hz); Slope (-12, -18, or -24 dB per octave); Phase (Normal/Reverse); or you can also select full-range Note: The DSP function can be bypassed. Equalizer Control: Equalizer Control allows you to use one of the System Q presets, or set your own custom settings using the 5-band Equalizer. The EQ adjustments are as follows: Preset EQ: You can select from Natural, Rock, Pops, Easy, Top 40, Jazz, Game, iPod (you can select from 22 EQ curve types), or User. 5-Band EQ: The User mode allows you to adjust the following 5-Band EQ (62.5Hz, 250Hz, 1kHz, 4kHz, 16kHz) settings. Band Levels: Independent front and rear EQ level of -9dB to +9dB. Bass Effect: Enhances the bass response of Band 1 (62.5Hz). Note: You can store equalizer settings for each source (CD, Tuner, Aux, USB, and iPod/iPHone). Position Control: For a better sound-stage you can select your optimal listening position. You can choose from All, Front Left, Front Right or Front. You can also select to manually fine tune the sound stage by selecting the distance for each individual speaker in the vehicle compared to your listening position. You can select between 0.00 to 14.44 feet for the Left Front Speaker, Right Front Speaker, Left Rear Speaker, Right Rear Speaker, Left Subwoofer and/or Right Subwoofer. Audio Preset: You can register two audio settings into the unit's preset memory to be recalled at any time. The Audio Preset memory can save Car Type Selection, Speaker Setting, Fine Adjustment, X'Over Setting, Equalizer, and/or Listening Position. Bass Boost: The Kenwood Excelon KDC-X995 features a two level Bass Boost to increase bass levels. Highway Sound: This features compensates the low volume or bass sound being lost by road noises to make vocals sound clearer. You can set the Highway Sound function to 1, 2, 3, or off. Dual Zone: The Dual Zone mode allows you to output the Main source and the Auxiliary input separately for the front and rear channels. You can select whether the auxiliary input will play in the front or the rear. You can adjust the volume of the rear channels independently from the front channels (0-35).

The issue with the orphan 8 will be impedance... Single 6 ohm coil... It is one hell of a sub and built by an American company.. I would kill to have some cash free up and try to get my hands on 6 of them.

Just tossing this thought out there, is the height restriced to 18.5"??? Because using 3/4 mdf and your design your front baffle is only 17" tall, that doesn't leave any wiggle room for driver placement.

I personally like the tubing design better. I'm not saying that dual ports are impossible, or even have an audible difference than a single port, but with the design you presented, I feel as if if the ports are set up backwards, you would be better off having the inside port opening (aka inside the box) closer to the sub instead of the wall because you are creating a port restriction by blocking off the pathway of air with the port itself.

Is your box ported and ~.6 cubic feet? Sundown builds amazing stuff, and has some of the best customer service in the industry, and that 8" sub gets tons of good reviews... Seems to fit your build perfectly and budget.

Don't do it. I highly doubt that it would even work, but as mentioned even if it didn't put the amps into protect you will most likely damage one or both amps internally.

I would agree either: 2 18" BL's or SSA Xcons Eventually I would look at upgrading amps, something closer to 2000 watts.

Cone area should not effect transient response, a properly built and tuned box will sound clean... The issue with trucks is that it is completely too easy for subs to overwhelm the mids and highs in such a small enclosed area, so less bass is needed to achievable a similar "loudness"

They are lackluster mainstream subs, nothing fantastic about them.
