Please build a DD Z killer! Fi FTW! We`ve got some proud DD owners, and they make fun of my Fi.

Hy, I want to upgrade my midbass amplifier (focal 165k2p) and I don`t know wich one is better for my set up (alpine 9835, focal k2p mid, hybrid L1 Pro tw). The Hybrids are moved by a small Zapco Z50S2. So: 1.JL 300/4V2 ~200+$ 2.Zapco Z150S2 My link My link2 ~150$ 3.Zapco 350 Driving Force: Stereo, 4 ohms: 2x100 Watts Stereo, 2 ohms: 2x175 Watts Bridged, 4 ohms: 1x350 Watts T.H.D. + Noise: <0.015% S/N Ratio: >95dB Slew Rate: >29V/uS Optically isolated MOSFET power supply Surface mount technology w/1% resistors, precision caps, and massive ground planes ~ 320$

I allready have 2x150W....I wan`t more quality, more SQ from an amplifier for my mids, not pure power:P. I was told that the JL is very good for a "&quot;SQL&quot;" aplication(i know it`s a forbiden word:P), something like loud and clear, not true SQ....what can you tell. Yap, i`m from europe, good damn the shipping`s costs.

Hello again, Now it`s the time for some SQ after some flexxin` (ex: and hihi ).After 6 months of BoomBoom and re-listening to some local SQ cars(some brax users, scanspeaks, focal, microprecision etc) I bought from a friend (who upgraded to microprecision) a set of Focal 165 K2P woofers and HybridAudio L1 Pro tweeters and an Alpine 9835. Now I`m sounddeadning my car, especialy my front doors with 1layer of SS Damplifier Pro+Spectrum Sludge+Damplifier+OverKill pro. Amps: HAT L1pro: Zapco Z50S2; Focals: Premier; Fi Q15: US Amps XT4000(1500W@1ohm load). What enclosure should I build for an SQ setup....a 2cuft or...2.5-2.6 cuft? The subwoofer is behind the front stage, is not quick enought in this 4cuft@32hz BR box. Thanks.

Any info on Hollywood Energetic batteries?

Hy, (excuse my bad english) what do you know about Hollywood Energetic(link), it is a replacement for Stinger SPV, I also heard Hollywood is a mix of Stinger and Kinetik, but I don`t really know if this is true... So, 1. Hollywood SPV 70 vs Power Cell 2050 (300 vs 330 euro); Hollywood: 70 Ah Nom. Capacity, Cold Cranking 900 A, Pulse Cranking 1700A, Short Circuit 3500 A Power Cell: 56Ah, 2050 Peak, 3500 A (SC) 2. Hollywood SPV 100 vs Power Cell 3000 (400 vs 390 euro) Hollywood: 100 Ah Nom.Capacity, Cold Cranking 1200A, Pulse Cranking 2250A, Short Circuit 4500 A Power Cell: 95Ah, 3000 Peak, 4400 A (SC) offtopic: 80Ah stock alt,BIG3 coming soon with: us amps xt4000.1(120A fuses, class D) and pioneer gmx1024(60Afuses, class A or AB) amplifiers, do you think 1.SPV70/PC 2050 is enough?

I have sealed doors, should I use this kit or i`d better buy more DamplifierPro?

Hy, on my XT4000 box it says CEA, is it CEA rated? It is an US Amps, not the new RE Audio XT4000.1. I want the CEA ratings for this amp please.

Bump, anybody, please? I want the dimensions of the box designed by Scott @30Hz. Thanks!

Hy, I need help with my new box, as the topic title says. My car is a Mazda3 hatchback; the sub-amplifier is USAmps XT4000.1 (on it`s box it says "CEA" ), I don`t know if my version is overrated or will provide 1500W@1ohm. I want my Fi to play loud, and as low as hell . I`m thinking at a box tuned at 28-30hz. Can anyone help me with a project? I`ll measure my trunk and i`ll post here the max. possible lengths for the box. PS: I`m gonna use the stock HU with a MTX Re-Q sound procesor...

UP; does anyone have an enclosure project made by Scott for this speaker? I know that a few guys on this forum have the 30hz tuned enclosure designed by Scott; I want to try it too, so please, post it here, or email it at [email protected]

Im just wondering. In my next van build, i should just order some boss or wolfenhags or somthing to test with? Sure, any subwoofer can be loud in the correct enclosure. Don't make me go and dig up the 150db video with Sony Xplode 6x9's. Yeah, I wanna see that video too.

I have the XT4000, but if I could afford, i would have bought an US Merlin MD2. Go for the MD1, if you can not afford the MD2. Keep in mind that Merlin and AX ar US Amps high end series, and that MD`s are "bridgeable with multiple MD amps". XT is not!

You were right, Greg answered me; the main differences are: upgraded input and improved muting. Thanks!

OK guys, thx a lot, sorry for being such a noob!

Welcome; glad to see a girl bass-head.

I really love Focal sound, even if it`s Polyglass series, they do sound nice. In the right set-up, they can be a true SQ system.

If my dealer accepts, I`d probably pay another 100$ for that.

I want to build a box that will flex my car, just4fun; it`ll play Put on, white girl, bets4myvan etc. I`ll keep it for a month or two, after that i`ll start to listen to music like jazz, jean michel jarre etc; so i`ll cut the port or i`ll build a closed enclosure. I don`t really know if I want it low or loud, but I certenly know that I dont like high loud bass.

Thanks! I`ve asked you so many questions because I wanted to trade my US XT for a RE XT....

Yes you are right, but it`s class D vs class DE, so wtf is class DE; couldn`t find any info on google. Is there a US Amps representative here?

Thanks for your feedback, I feel much better now, being mad though. I don`t want to start a new topic, so I`ll post here: does someone know for sure if there is a difference between US Amps XT4000.1 and RE Audio XT4000.1V2. The new RE A. XT4000V2 is Class DE, the US is Class D. Can someone explain me the differences between classes and these two amplifiers? US Amps RE Audio
