haha but he would never notice an old crossover stashed in the trunk. but honestly i dont know what to look for here.. A Coustic XM-7 would be saweet. No t/a, but he won't notice and you get crossover and eq and it will ALWAYS be worth what you pay for it. impressive unit. now to track one down.

NOS?

thats a possibility.. That would allow you to put the headunit dough into a processor. Might be safer since he can't dink with it then. 5 mins of searching...not very familiar with inline processors but im pretty sure the ms-8 is out of the budget... found these mentioned somewhere jbl gtx47 4way crossover -$70 jbl gte422 -11 band stereo or 22 band mono eq - $65 looks old school haha. but crossover is listed as "new". no TA lol just realized i ment to add sarcassism to this post.. i ment this ^^^ no way these things are new rofl

thats a possibility..

He has a used equipment budget, so either budget or expectations need to change. the budget cant go up so i think the goal is to spend as much of the budget as "wisely" as possible... what do you think of a slightly ghetto 3" wideband and midbass option? the 3inch would have to play down to about 250 to use that kenwood deck i mentioned.. otherwise i would have to hpf the 3" and lowpass the midbass at the amp. edit: given the low processing ability of the deck i doubt this is the best idea.. maybe it would be best to scratch active off the list and look to a passive option.

At the same time he referenced a decrease in efficiency to allow it to play lower. Still should be more than a "normal" driver. missed that.. "pro 8" is a bit misleading maybe

although there are no t/s specs yet, he mentioned they have high efficiency so the 100.4 should be fine to power them. also, the 100.4 will do more then 50 @ 8 ohms..

denim, where are these new icons at? haha id love to pick one up for my bro's install. link link btw, m5 i talked to my bro and i cant get any used equipment , any advice on the hu?

X'Over: The Kenwood eXcelon headunit 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 (40, 60, 70, 80,100, 120, 150, 180, or 220 Hz); Slope (-12, -18, or -24 dB per octave); or you can also select full-range Rear High Pass Filter: Frequency (40, 60, 70, 80, 100, 120, 150, 180, or 220 Hz); Slope (-12, -18, or -24 dB per octave); you can also select full-range Subwoofer Low Pass Filter: Frequency (40, 60, 70, 80, 100, 120, 150, 180, or 220 Hz); Slope (-12, -18, or -24 dB per octave); Phase (Normal/Reverse); or you can also select full-range 3-Band EQ: The User mode allows you to adjust the following 3-Band EQ Bass: Frequency (60/100/160/250/400 Hz); Q-Factor (0.25/0.5/1.0/2.0); Level (-9 to +9 dB) Mid: Frequency (0.63/1.0/1.6/2.5 kHz); Q-Factor (0.25/0.5/1.0/2.0); Level (- 9 to +9 dB) Treble: Frequency (4/6.3/10/16 kHz); Level (-9 to +9 dB) using the kenwood deck we could do a 2way + sub using a 3" full range and midbass. we would also have a TA and a limited 3 band PEQ Fountek FR88EX 3" Full Range and peerless sls 6.5"?

i started a thread awhile back for my bro but plans have changed and his financial situation has improved so im back again. budget is 1000 bucks for equipment and materials. these are some of the things he's looking for; crisp clean sound upfront solid bass without taking up much room quality equipment (he wont buy anything secondhand) car is an 04 nissan sentra, (base model ) left over equipment from his previous build are just subwoofer amp, but no sub (his l7 got fucked...) and some wiring. unfortunately they didn't get the set of pg rsd's out either i've considered two basic systems, the first with a passive front stage and the second with a active front stage. this is a list of equipment i've picked so far headunit kenwood kdc-mp745u - 150 - notable features include 3 2.5v outputs, 24 bit dac with ipod control through usb, sexy looks and 4 line display, 6 channel TA (in feet), or kenwood excelon - 150 - same as above but with 4v outputs (online seller seems less legit) 4 channel amplifier for front stage -not to sure about this idea, i've seen these used in a number of builds recently. iirc, here on ssa sefugi used them in his son's build soundstream dtr4.500, 130 bucks shipped subwoofer - i have on tap approximately 1000rms at 2ohms depending on electrical. and given my bro's listening habits, at the top of the list would be a SSA icon 10, ported. ~250 bucks iirc also considering fi q, or bl (probably more towards the bl), or maybe 2 sa-8s.. previously he had an 15 L7 so i dont want to step down too far from there. although he liked the L7 sealed more then ported. - im trying to picture how this build should go together, i was thinking about walling off the ski pass but sealing the rear deck is very difficult and the results might be underwhelming. on the other hand rear firing the sub would result in alot of rattles.. input here would help... -id like to keep the spare tire assessable. not sure if ill do another false floor like i've done in my own car. i think another option would be to mount the amps to either side of rear tire wells with the sub box in the middle. also use a sheet of mdf to replace the floor of the trunk, with a hinged section to access the spare. which would allow you to fasten the sub box to the floor. deadening SDS, enough said.. i haven't contacted don yet, im thinking there will be somewhere between 80 to 120 dollars in the budget for deadening. that would be enough to at least, do a full treatment for the front doors. --------------------------------------- ok here is where i'll break it down into the 2 options of active front stage or passive. from above, we've "spent" 150 on hu, 250 on subs, 130 on an amp, 120 on deadening, for a total of 650 bucks. id like to leave 100 bucks for wood, wiring, distro blocks, volt meter, etc. so with the remaining 250 bucks we could either buy a simple passive set, possible saving some money with something like the pg rsd's for about 90-100 bucks now days or spend all 250 on a nicer set. or attempt to squeeze together an active set up. here is my idea for the active setup: -miniDSP w/ advanced 2way plugin (pdf) - for those not too familiar this would allow for 6 bands PEQ per input, 2 way xover per input (bandpass filters), 6 bands of PEQ per output (4), TA, and individual gain. for 135 shipped. which leaves 115 bucks for 4 speakers!! speakers btw, could be up to 7 inch's (w/o cutting) and lets assume depth is no issue for now. not sure when he'll be home next for me to go out and measure. i know his doors are not very deep but that doesn't mean i wont cut them the fuck up.

its just to control the tweeter output. 0db would be flat. 3 db would double the power to the tweeter (louder), -3db would cut power by half (quieter). btw, 3db increase doesn't mean the tweeter would be twice as loud just slightly louder. a change in 10db is considered to be twice as loud. which do u set it to? you will have to try each setting to see what you like. if the tweeter is too bright turn it down for example.

Oh come on, Quantum is fun. Yes I am a Physicist by education, lol. lol, dont get me wrong, Quantum is very interesting. Ugg, I much prefer Classical. i haven't quite decided yet. ehhh im in no hurry

im trying to come up with a list of pro's and con's for going with a single h/u solution vs the h/u miniDSP combo single hu pro's -everything at your finger tips (my bro wont know what anything does so this really wont matter too much) -less shit in the signal chain -easier install -potentially cheaper if bought used con's -my bro doesn't understand shit about car audio so the features wont mean much to him -probably would have to bought used -older units might not have ipod control** minidsp and hu pro's -uber processing power -new products with warranty (probably wont be very useful if they are required to be professionally installed) -software seems very easy to use according to reviews con's -i would need my pc present to do tuning (but since i would be the only one able to tune the system this isn't an issue) -possibly more costly -more shit to install

im trying to find some model numbers for older model h/u that can do 2way+ sub. here are some alpines i've seen listed but i haven't check to see if they can do whats needed yet. 9813,9815,9833,9835

2 tops in a row! not even trying guys

Oh come on, Quantum is fun. Yes I am a Physicist by education, lol. lol, dont get me wrong, Quantum is very interesting.

which h/u do you have in mind? if it was my money i wouldn't be buying anything new but he's very concerned about getting a damaged product.. ill be the one ordering so i could probably order a few thing used/refurb off ebay but i doubt he'll let me, for example, buy a sub from another forum member. it really sucks since im seeing alot of nice equipment in the f/s section..

hello hop, been awhile.. i've started a thread here for my bro... wish i had time to catch up on the hop but im a little too busy tonight i have to give a small presentation on Phonon's tomorrow night... bleh why is quantum mechanics so hard to understand... wiki - phonons

dont worry so much about power. a decent 100x2 rms 2 channel amp will be fine. on the cheap side you can find a used or refurbed kicker 250.2 or something similar. sundown makes some great amps, 125.2 would be awesome. something that hasn't been mentioned but very important is install and deadening. check out sounddeadenershowdown.com

interesting design, very cool

pretty sweet tablet. only $250, not bad

ummm whats the word im looking for... ...gimmick?
