I'm almost tempted to order both the earthquake and RF and measure what one does best! Send the looser back.... If you were to just go by SPL specifications (dB @ 1w/1m), you might think the RF would be better, but just looking just at the XMax Paramater the SPL at full tilt would easily go to the earthquake. That is a lot of throw difference. The earthquake is 23mm The RF is 7mm That being said, an 8" sub with a 23mm one way excursion is a sight to see. Really, I've never heard of a thin 8" having that much movement. I actually wonder if that is real, or if the spec is fudged? Can anyone confirm that its excursion (min to max) is close to 2 inches? From the pictures, the surround doesn't even look like it would physically work. If it is real, that throw is simply amazing for such a thin speaker! I would think it would be smacking the grill that goes on top! .http://www.earthquakeeurope.com/Prod..._manual_US.pdf There is a paragraph in there that talks about the excursion Also watch this video seems to suggest it may be real: Last edited by JMon; 10-31-2016 at 07:59 AM.. |

AUDIO CONTROL LCI2 Is the key...i that as a line driver , high-> low converter...key here, may seem obvious but t splice into the stock subwoofer wires coming out of the stock amp, forget colors but the 4 thicker wires 2 pairs twisted...the stock dsp has great crossovers if u grab other wires ur not going to be getting the deep lows...
Also Idk if its been said but if adding aftermarket sub/amp ASD must be coded out... I never noticed ASD...and I hooked up my stereo...2 RF P3 DVC 12"S 2ohms W Kenwood 3000w 1ohm stable amp. Speakers in dual vented box wired in parallel to 1 ohm. Hooked it up sounded great...went to drive in sport+ (where ASD Is loudest) and u almost fried my stereo... Showed me ASD is mostly loud i lower frequencies...so also by disabling asd...ur stock subs will sound better bc they're not wasting power on fake engine noise |

I want to add a sub to my M4 convertible and already have both a sub and amp. I would would just need the LCI2. I thought the sub amp was located in the trunk? Does anyone know the wire codes and where I could tap into them instead of running extra wires from the stock woofer locations?

will this fit? : Rockford Fosgate P3SD4-8
It can be it has two drivers and can be connected as 8Ohms. Is it true that the AMP then will not heat up and eventually get destroyed if I go down this path? https://www.crutchfield.com/p_575P3S....html?tp=68848 |

I'm just trying to avoid putting together another AMP.
Is it possible to install a higher watt wirebound resistor in series with the SWS-8X x2 to achive impedence that matches the oem amp? Here is the wirebound resistor. https://www.mouser.com/ProductDetail...gEbY%2fg%3d%3d |

Can I add a powered sub via speaker level inputs?
It sounds like I can tap into the subwoofer connections on the HK factory wire harness in the trunk. Has anyone done this and figured out exactly which wires to use? Which one is the turn on wire?
I am trying to connect a powered subwoofer. https://www.crutchfield.com/p_575P30...10.html?tp=114 Crutchfield sent me a harness diagram but it doesn’t match my F80 at all. Is it better to connect this using one of the harnesses I see or just pay someone to do it? |

There aren't any generic amps that will last through 30V spikes, even if the Impedance is much lower....BUT A good LOC, Line Driver, DSP can turn high level inputs into low level and fill in missing audio informtion s well s other features....I Use Audio Control Products...The LCi2 works insnely well to prevent roll off and open ur options....That with the Hifonics Bass Restortion processor....Im anal with audio and very happy...ppl cant believe I only have one P3 12" DVC wired to 1 ohm with a 1 ohm stble 2000watt RMS Kenwood Amp....Also spray insulted the trunk...only draw down is i need to leave 1 or both back seats down or you barely hear the bass...And had to fix a few rattles...

would you recommend the SWS subs replacements to be 4 ohm or 2 ohm?
and would you go with a Class D amplifier (mono, 2ch)? How much power you think? I read the subs there go to 200hz and most class D amps go to 150, would this have a huge sound gap?

Hello,
I recently upgraded the factory amp to JL for the interior speakers and added JL subs and JL amp for the sub. sound is great and clean! only issue i am having is the GONG/PDC sound is too loud. Are you experiencing any of this? I turned it down on the HU -5 but still too loud as the speakers are powered with AMP. any advise? |
