Default recommended 5.25" components to be powered by Basslink 4SC amp module

Hey all,

I've got an Infinity Basslink II on the way, along with the Basslink 4sc amp module (see gah!cantpostlinkcausenotenoughposts since Infinity's site seems to be having trouble at the moment). Stats are as such:

o 4-channel amplifier expansion board for BassLink II
o 35 watts RMS x 4 at 4 ohms, 50 watts x 4 at 2 ohms
o HU is a Kenwood Excelon KDC-X791
o fronts and rears are both stock atm - I plan on leaving the rears alone
o Budget: $200 (ok..$250 *max*!)

I'm curious as to what might be some recommended 5.25" components for the front doors that would be sufficiently powered by that amp with decent sound quality. I'm open to coax as well; I'm mostly interested in the best sound I can achieve with the dinky 4sc amp and a new set of fronts.

Also...I say 5.25" since I assume there'll be no 6.5" comps that would be sufficiently powered, but I'm open to those as well if they exist. The ease of installation of the 5.25's is attractive, however (spacers + door pins + door card trimming + window track washers + screw grinding + magic circle + chicken sacrifice is a bit much for me - the HU install was my first DIY car audio project). I'll be using Dynamat or RAAM mat or similar for noise damping.

The car is a '04 WRX sedan. My listening is mostly electronic music, and mostly in the Goa/psychedelic trance realm, along with a lot of downtempo (think Hallucinogen & Shpongle related stuff, although I listen to a crapload of other types music). As for sound preference, I'm fairly sensitive to bright tweeters and my ears fatigue pretty easily with too-high of highs, so something smoother and warmer is where I'm leaning.

I understand I'd get a more well-rounded system with a nice set of 6.5's and a separate amp to power them, but the way the planets are currently aligned, something "pretty good" is what I'm going to have to go with (even though I'd love to go nuts and spend stupid amounts of money on the setup).

Thanks in advance!

--Marsh

ps. I plan on listening to some sets this weekend, but where to focus my energy would be super helpful.

Look at the Polk DB line... Maybe even the MOMO line...

There really isn't that much difference between a 5.25 and a 6.5 in the same line as far as "amount of power required" goes...You'll be nearing the lower range of powering components, but anything is better than powering them from the head unit...

MMATS pro audio and Zapco are good but if your looking for a good low cost efficient alternative check out www.madisound.com and go for some vifa drivers and tweeters but you will still need xovers.

spend the money for a 6.5 over the 5.25, and don't worry about the power issue.

Just make sure you find a very effecient speaker and size will not really matter.

Efficiency is the key.

Actually it's more about me being lazy and less about the money. I'm just looking for some nice 5.25" speakers that'll fit the amp's power well without having to do all the spacer/window track/door card pin business...

Did a bunch of research today (never did get out to listen to anything) and so far, these are the front runners:

Pioneer Premier TS-C520PRS
Polk Audio MOMO MMC5250
Focal Polyglass 130 V1
Infinity Kappa 50.7cs
Polk Audio db5250

The Pioneers (TS-C520PRS) sound - sound as in "what i've read on the interwebz" - right up my alley with a warm, rich sound that's not too bright. They're sort of in 1st place at the moment due to efficiency and sound reviews. The Polk MOMOs (MMC5250) also sound like they'd match my listening taste, however they want quite a bit more power than the Pioneers (100W RMS vs. the 30W RMS of the Pioneers).

I'm more of an audiophile in concept than in practice, and unless there's a full-on NIGHT & DAY difference between the 5.25 & 6.5 sets, I'll probably be just fine with the 5.25's.

Guess I need to just get out there and listen and make up my own damn mind!

laziest bet is to get the same size driver as the stock size and put it together with the harness/space/bracket/whatever that you can get at crutchfield or something.. but it's pretty much the same thing though.. any aftermarket speaker you buy to put in your doors will require spacers

To be honest with you I have liked Pioneers sound since I was a young lad... 15+ years now anyways... They have yet to disappoint me (as far as value anyways) I know they are far from the "BEST" but they are a great value for those that arent into competition etc...

I still rock pioneers in my STi and I love them. Oh and FYI my pioneers didnt need a spacer tho my doors are matted heavily so that might be the reason. It was a very tight fit tho (but didnt have any clearance issues.)

I have had the 6.5" version of the Premiers installed for a few weeks now. They are very nice for the money, lots of midbass and pretty good tweets. I don't think I'd trust the RMS rating from Pioneer though, these are very beefy drivers. They don't seem particularly efficient to me, although the 5.25" set might be different. I am running them with ~230w per side, and they take it with no problems.

Alright, now I'm leaning back toward 6.5's.

I was thinking about how the Kenwood KDC-X659 w/22W RMS powering a pair of MB Quart DKD-116 coaxes (wanting 50W RMS) sounded *great* to me in my old Tacoma. So, if at less than 1/2 of what those 6.5's wanted were sounding fine to me, I'm thinking it'll be gravy with the Basslink 4sc pushing 35W RMS to the 6.5" Premiers wanting 50W (as some of you told me already...heheh). Although, yes, I'd most definitely NOT be doing them justice.

Also, since I'll be in there anyway getting nutty with RAAMmat and Ensolite, and I've already got some of the Kartboy spacers on the way as well, I should probably be not-lazy and go for the 6.5" Premiers.

@khail19: How difficult was your install? What spacers did you use and what thickness? Did you do door the card pins? I think I saw on DIYMA that you actually cut your window track? (can't find that post now...grrr)

Thanks for the feedback so far, folks!

+1 on this suggestion. I have the Peerless poly 6.5 and Vifa XT25 Neo's. I can send you the xover schematic (designed in LEAP) and Madisound will send it built just for the cost of the parts. My set-up sounds as good as the F1 Alpine and Polk SR systems for 80% less.

I had previously installed the extended door pins and 3/4" spacers with the old speakers. I had also previously ground down the white plastic nut on the window, although I don't think that would be necessary with the Pioneers. When I tried to install the Pioneers, the problem wasn't with the glass rolling down and hitting the top of the magnet. It was the metal track that actually hit the side of the speaker on it's way down.The magnet on the old speakers was actually deeper than on the Pioneers, but not nearly as large in diameter. These speakers have a metal cover that surrounds the magnet, which seems removable. There are 4 Allen bolts that screw into the back, but even with them removed I couldn't get the cover to budge. Not wanting to take a chance damaging the speakers, I elected to damage my car. I could tell by the wear marks on the track that I could safely cut a bit off the end (about 3/16"), so I whipped out the Dremel. The windows still work just fine, I haven't noticed the slightest difference.

In my mind the install was not that difficult, but I have no qualms about cutting up my car. Right after I bought the car I cut a large hole in my hood using a Sawzall so I could mount a scoop from a WRX. After that, cutting up my window track seems rather trivial.
