System planning

OhTwo · Post by **OhTwo** » Mon Dec 05, 2005 7:41 pm

Car:1976 BMW

4in in the doors ( garbage )
6x9 Alpine Type-S on the rear deck
Set of sony tweeters, that were gutted from some terrible sony speakers- -Mounted on the A pillars
Blaupunkt headunit
Cheap sub and amp which has been removed.

The front stage is acceptable when the fader is set towards the front, but the 4in speakers show their size. The rear speakers greatly improve sound quality when used, but kill the stage.

I'm a soon to be college student, so money is tight. What should I do for an amp? Brand? Power? How about a componet set for the front? Infinity Reference?

After discussing this with ridr4lif, this is what we came up with:

Amp 50W x 4 or something similar. Not sure about brand. Price is a major consideration.

Front componet set- Infinity (Reference?) with the 4 in driver in the door and the tweeters on the A pillars.

The rear speakers will use the low pass filter to provide bass, that the front set will be lacking.

BTW- Power is a major problem due to the 45 amp alternator. This means no huge amps and I'd like to avoid a sub.
Thank You

Front stage:
1) Memphis M-class 6.5 coax set $145 or component set $169
2) Alpine Type S components $139
3) Type R components $249

No rear stage

Amp: Rockford Fosgate 4004 50x4 @ 4ohms incase you add a rear stage later.

I would create a custom Pod for 6.5 in the kicks or in the door to add a small amount of midbass and get rid of the 4" driver.

If a sub is considered heres a few ideas

1 RE10-like $65 shipped i think

Rockford Fosgate 4002 200x2 at 2ohms for the sub.

KnuKonceptz wiring cuz its cheap and nice, like $30.

Maybe that will help, I just priced all that to go in a 37 chevy street rod with my dad and i liked the setup so thought maybe that would help.

here are my gripes... no rockford amps go with arc or a dx80.4 from elevation. drop the memphis ad a pair of cdt dls or bravox components.

I can't fit 6.5. Maybe 5.25, but I don't want to cut up a 30 yr old car. That's why I want to use the rear speakers. I think I will need to compromise. I know this is stupid, but I want to keep the current speaker locations. Foam baffles at the most.

I don't plan to keep my sub, nevermind buy another. I still have all my wiring in the car from the sub, so not much will be needed to add a 4 channel amp.

I appreciate your help, keep it coming.

i stick with my coments get a pair of decent components look at the brands i listed above and also look at the elevation audio component 5.25s for the rear deck im out cause i dont like 6X9s and it sounds like you have your heart set on those... the type r's arent bad but i would much rather use a 6.5 speaker back there but thats just my preferance.

go to the import salvage yard...it is a bmw so "junk" yard didn't sound right, anywhoo..look for a set of spare kickpanels for your car. You should be able to get some for about 40 dollars. Then use the spares to fabricate you some 6.5" component fiberglass kickpanels. Use the space for the 4" for the crossovers. You didn't cut the car, you get the sound you are after and no need for subs. A good quality component set and the right amp will make it sound fantastic. I would try to stay away from a 4 channel amp. Just use the front speakers, and use a separate amp for each side of the component set. That is how my system is set up and it sounds phenominal! Hope this helps.

i agree. i was amazed at how well my 6 1/2" components sound in my kick panels. i didnt think id like the speakers that low and was contemplating putting the tweeters in the dash, but the first time i turned them on in the kicks, all my original worries were gone. i find myself turning my sub off completely alot and just listening to the comps. the imaging is fantastic

Arc Audio makes some nice coax's I run Arc Audio Kar 5022. Sound great, and don't need much power at all.

How about a 4 channel amp? Alpine, Audiobahn, and Profile are my considerations. Profile is probably out because of the low cost (quality).

No Audiobahn!!! No No No! Look At Some Arc Audio Kar Amps The Alpines Arnt Bad Look Into This Amp Its Decent For The Price Pioneer Gm-4000f. I Run 2 Of These And Love Them. No Problems Clean Power. Elevation Audio Dx80.4 Talk To Devin Justin Or Terry They All Sell Elevation
