The "Arc" series are amazing! !! VERY VERY clean, tight sound with great output

Kinda late to the party, but the Arc "black" series are not out yet....maybe September....Arc audio makes great products that sound amazing.....so its all about what you want to achieve...

Are you competing or just want good sound? Personally I keep my mid-bass & tweeter very close to each other. Also you need to find the off-axis frequency response of the speakers you choose to run & this will assist with placement of these. Kick panels are always better if designed right. The subwoofer you just have to play around with placement & enclosures..

Too much emphases is on the subwoofer & tweeter of a SQ vehicle. These play the least frequencies in the spectrum. You main concern is the mid-bass driver & placement. you want TONS of power (very clean) & this provides overhead for the system. you can use any subwoofer you would like, it's all about control, the enclosure, placement & some quality of subwoofer.. Typically SMALLER drivers work better. They can achieve full x-max with minimum power/volume where a 18" playing a 30hz tone might overpower the system.. So go with a 10" or 12" to be safe.. Nowadays you have advanced EQ's that can process just about anything & flatten the response of the subwoofer You need to focus on your soundstage!

Do you want brand new? Kicker Rockford fosgate Soundstream MMATS Digital Designs NOT AQ

Some amps it does not matter....90% of amps it DOES matter!! So just Y split it & if you have pulsing noise... then you have OTHER problems.. either bad radio or noise from the amp... Also, make sure your radio AND amp is OFF when messing with RCA's, it could damage the equimpment

That's the way you have to do it... Run a Y splitter at the radio or amplifier... I'm not sure why it was pulsing, my guess would be noise from the amplifier... you won't hurt anything by doing this..

idk if this way directed towards me, but I didn't say he could just flat out mix them. You obviously cant just wire the different speakers together. If each "type" of speaker is on their own amp, what's the problem? It's hard for me to explain over text lol Sure you can mix speakers on the same channel amp... NOT SUBS, as you never mix subs... It might sound like crap & you can't adjust them independently but it won't hurt ANYTHING...except sound & it's not under the proper ohm load.. To anybody reading this....please AVOID hooking up different speakers to a amp & even using DIFFERENT model speakers in your car...it won't sound good to add to this, back in the early 90's people use to run ONE amp for their ENTIRE system!! They had alot of other goodies inline to control the crossover points, levels, etc...but that's why the old Punch 50's became legendary!

I'm a FIRM believer of using a proper front stage with a good pair of components.. I NEVER, EVER use rear fill......BUT Being this is a HUGE car, he has a limited budget & it doesn't appear he even knows what a soundstage is...then more speakers will apply to him.. Sure you will have cancellation...That's why use SQ guys don't run rear fill but I always take what I want out of it... It's what MOST people want & if I told this guy to buy ONE pair of $200 components, then he will destroy them from the lack of output in this huge car... I'm not disagreeing with you.... but in this case, more will be better, even with slight cancellation..

You can mix/match all you want.. You CAN even put multiple type of speakers on the same channel (as long as it's not below 2ohm) & it won't change the sound. The problem is adjusting each set of speakers independently from each other. Some might be more efficient than others & be "Louder" due to this... How many pairs of speakers are you putting in this car? Personal opinion bigger speaker, bigger sound! There's no replacement, for displacement! One pair of GOOD 5x7" speakers or 5.25" components for the front... One pair of 6x9" speakers for the rear... I'm a believer of QUALITY over QUANTITY unless you want it just stupid loud for SPL systems...

Why do you want 2ohm components?

Have you got around to sealn em up yet? If so did it make a noticable difference? Jus askn cus I may have to do the same, I do got some spare second skin layn around. My crescendos move and sound pretty good but their lacking "bass"... Mayb its time for an actual midbass instead of components, couple 8's maybe..? Seal the all openings in teh door panel EXCEPT behind the speaker...(Seen it before) Ditch the Crescendos & get a GOOD pair of components... Look into some Hertz, T3, Focal, etc...
