    I think "car audio" batteries are a waste of money.

    You can go to Walmart and get 2X the Ah for about 1/2 the price... They will just weigh a little more. And if they don't recover from some hard abuse and get back to a float level you want, you just take them back. As many times as you want. Seriously. And they are about 30 min max from where you live...

    We used to swap out 5 at time before a competition. No questions asked. 5 new batteries fully charged...

    They sell one big pucker that is about $100 that is a monster, can't remember the part #...

    Or just piss away extra money on a "car audio" battery.... Just my opinion, of course ;)

    Have to agree. I use the biggest one I can fit under my hood, and the biggest one they sell in the trunk. I've replaced both a couple times over the years without an issue. They cost me about 100 each when I first bought them. Every time I get a new one the warranty renews. The only real downside is that they need to be mounted upright.

    Iv'e always thought that would be a good idea, but what about the fact its not a sealed battery in the trunk? Do you smoke?

    i already have an 8" setup i have a Rock fos. p2d48 and it dosent perform like i want it too but i also have a cheap amp that dosent have any power, so im replacing both! its in the trunk of a 09 malibu

    Can you build a proper ported enclosure? Whats your current box? Front stage? Budget? Need more info here.

    Are you wanting more bass?

    You will get the same quality sound from each driver. Think of the icon as a v6 mustang and the xcon as a v8. Basically the same machine however the xcon will provide more output being it has more motor force and xmax, but like the v8 it'll take a little more gas (power) to get the extra output.

    Exellent analogy

    Saw it on a news app on my phone, thought it was worth passing on.

    Heres the link to the actual report.

    http://info.publicintelligence.net/DoD-NLW.pdf

    http://www.theregister.co.uk/2012/01/04/military_non_lethal_weapons_revealed/

    Details of the US military’s wish-list for non-lethal devices have been published online and show some interesting new technologies, as well as some more familiar ones that are to be beefed up.

    The non-lethal weapons (NLW) book was posted online by researchers at Public Intelligence, and covers both existing weapons currently in use by the US military such as tasers and pepper spray, with new tools that the Pentagon would like to add to their arsenal. Such weaponry is described in the materials as vital for conflict resolution without force, and for winning the "hearts and minds" of the local populace by not leaving chunks of their hearts and minds strewn everywhere.

    “In past operations, the effective employment of NLW resolved escalation of force situations,” the document states. “Specifically, the NLW created the right 'direct effect' on the personnel/materiel targeted. The use of NLW has also generated positive 'psychological effects' on others in the area and helped to contribute to mission accomplishment.”

    The Raytheon Active Denial System microwave gun, which heats up the skin of target without (it’s hoped) causing injury, should be upgraded to allow the beam to be used over much longer distances. Ideally the range needs to be such that the device isn’t in potshot distance from small arms fire, although the amount of power required to do this may be prohibitive. The military would also like the units to be smaller and multidirectional.

    Also on the list is a Distributed Sound and Light Array (DSLA) which combines lasers, other lighting and acoustics to disable opponents. The system is designed to disorient people, but may cause retinal scarring and ear damage if used at close range.

    Existing technologies are planned for upgrades, including a new form of flashbang grenade to be tested next year that will blind people for ten seconds and subject them to a bowel-watering 143 decibels, while remaining “environmentally safe”. A 40mm grenade-launched version of the munition is also in the cards, as is a grenade version of the standard taser that could increase the range of such devices to hundreds of feet.

    Current shotgun-fired beanbag rounds are also to have their range improved and have dye markers attached so the recipient of the round can be identified later. Current laser blinding technology will also be beefed up – with a requested range of three kilometers - although the document does say that a pair of reflective goggles would put paid to this device.

    Some of the more esoteric devices include the "Subsurface Non-Lethal Engagement-Impulse Swimmer Gun", which generates a directional, underwater pulsed sound wave that can be used against frogmen trying to sabotage shipping. The device will induce disorientation and nausea in swimmers within a 150m range.

    Those weapons still at the conceptual stage include a pulse generator designed to bring down individuals by firing nanosecond electrical pulses at them until they lose muscle control. A similar system is also planned for stopping cars by overloading electrical circuits, and the Pentagon envisages an aircraft-mounted microwave generator that could be used to fry the electronics of shipping, either on the high seas or for landing craft making an assault.

    However, the El Reg prize for the most ambitious NLW on the drawing board is the Laser Based Flow Modification system. This will be used against enemy aircraft to get rid of them without killing anyone, by firing lasers at the leading edge of an aircraft’s wing. This will alter the amount of lift generated by the wing and allow the aircraft to be turned away – or at least that’s the theory. We suspect it’d still cause the plane to crash, but for chutzpah it takes some beating. ®

    System will be going into a 1983 Cutlass Supreme, cousin to the more popular Buick Grand National and Monte Carlo SS. Head unit is a Kenwood x994. Front stage Focal 165 v 30 bi-amped. Mids/highs amp (2) RF Power 551s. Subwoofers (possibly 2 x 12" Dcons). Sub amp is a RF Power 1051s. If there is anything else you guys need let me know.

    I wasn't sure if having more than rated power would make the box specs change. ~ 1100 watts for the pair???

    If you plan to throw 1100 at the pair (would'nt recommend it) id shrink the box a bit, but it seems to me that that power would be better suited for either SA-12s or Obsidian 12s, or even skars. I don't think youll benefit much by by doubling the Dcons rms.

    I don't use any fancy batteries in my system. I use two 1050 CA batteries that I get for $75 a piece. I also have a 40.1 and the voltage stays nice and high with no light dimming in my Jeep. I also use 2/0 gauge wiring and run my 40.1 at .5 ohms. That's my .02

    I don't get what cranking amps would have to do with car audio. You should be looking at amp hours or ah. Cranking amps were more of a deal when every car had huge v8 engines and were hard to crank over.

    Cranking amps are very important, thats how much current the battery is capable of producing for 30 seconds. Very important thing to know especially in a competition situation
