I have an old crate amp (well, not old, but the head is blown) so the speaker is still good (10") and I was wondering, if i was to get a new head for it (it was a crate gtx 30 (i think GTX is right?) if i can, how would i have to set it up if i was to put it in the trunk of my car? and what would someone recommend me for a cheap, small, do-able head?

It's my new goal in life. To rock my bimmer like a V-Dub! but with a better amp :-P
I just wanna' go home.

UMMMM... an amp for your car?

What are you running it on? Hopes and dreams?


Just get another Crate. They are probably going to be the cheapest amp head available. Maybe $180 (or so) used off of Ebay.

how do you plan on supplying electricity to it?

maybe one of those amps from those boom-go-thump thingies all the wiggers put in their cars so they cant hear the music....but i dont know how those work or if thats possible...i could use a DC converter and put a cigarette lighter in the trunk....but i dont know how the power stuff works...like..wattage and if i can get away with enough power or if ill over power the amp or what...im really not that smart.

oh, btw....yes, I am running on hopes and dreams, as i dont have a job to afford any gas!!! but yeah, i'll get there....one day!!

yea, bud. a power converter would work. by the way, you cannot overpower the amp. it only takes what it needs....like immigrants.

Generally speaking, most higher rated systems (anything more than a basic head unit [deck] are run straight from the battery, such as power amplifiers for subwoofers.

I don't think you could run a considerable amount of power from a cigarette lighter, let alone enough to power an amp... that's assuming you managed to figure a way to wire it up so it would work (a tough enough thing in itself.) Drawing that much from the electrical circuit there will probably cause a short somewhere in your system. BMWs aren't cheap to send to a shop and if you can't fix it yourself (or have limited funds) you'll probably be screwed.

To wire it up (theoretically), you'd probably want to somehow tap into the effects loop, or barring that, before the poweramp. You don't want to use the preamp here, because I'd think that would be unessicary at best.

Second, you'd want to use the Sub-Out feature on your deck (CD player, stereo, whatever) because it doesn't carry an exceptionally large current like the ones which go to your speakers go. Also, often times these already have crossovers installed so you don't have to buy one to filter the frequency range.

Then, you'd have to run a hot and ground wire from the battery (Use the proper wires, not speaker wire. you can find these at a car stereo store) from the BATTERY CABLES (the part that clip to the battery) and through your car. There are several ways to do this, usually you just find a nice place to put them through the firewall and run them through to the trunk.

Now, the part I'm not sure about, you'd have to find a way to filter, dampen and convert the battery power to something you could use with a guitar amplifier. I duno how you'd do it.


Now to the problems:

A: Subs and amps are less expensive than a guitar amp. That's what they're for.

B: Guitar speakers are for playing guitar, not designed to produce the uber low frequencies that subs do. This means A: It will probably sound terrible and B: it will probably destroy the speaker rather quickly when turned up to any decent volume.

C: Power is another problem, not only would it be hard for you to RUN the amp, but the amp probably wouldn't be loud enough to make a decent sub anyway.

Also: You drive a BMW. Be proud. Don't desecrate your car into being a "v-dub" because BMW are (and will always be) on a completely different tier of auto manufacturing, luxury and performance. (at least you got the slang right )

I don't know about your car, but mine is rated at 150w at the cigarette outlet. So long as the amp draws less power than that (keep in mind output power is different from input power), you could get a DC-AC converter designed for a car (they sell them at auto zone) and plug your amp into that. Check the back of the head, it should tell you the rated input power (which will be much higher than 30w).

However, I hope you want to put a guitar amp into your car in order to be able to play guitar. What genocide said about frequency response is absolutely correct. A guitar amp is designed to handle guitars, not the wide variety of instruments stereo systems need to be able to handle. I don't know why you'd be playing your guitar from your trunk, but that's the only use you'd get out of this.

Just run a power inverter (12v to 120/240v depending on your country) and make sure it has at least double the rated output as your amp takes. Don't wire it through your head unit as you'll ruin your speakers.

Also take note that this would put a pretty large drain on your battery I'd think.

So..

If you DID want to play guitar in your car.. you could always get a second battery + battery box, put it in the trunk and wire it up proper and work it that way.

Otherwise you might stop jamming out and find yourself stranded in need of a jump

In Australia, cigarette sockets are limited to 10A, so the most you will be draining from your battery is 120w. Considering most audio systems are at least double this, I wouldn't be too worried on draining your battery.

I have a power converter that I use on long trips to and from school in the van. It plugs into the cigarette lighter and has 2 standard AC sockets on it. I've had my laptop charging and running my 360 on it at the same time before. Now, I'm not sure how much wattage that is, but I'd assume that it would be able to handle a guitar amp (not sure how big you want to go with the head, though).

I'm currently fixing up an old panelvan and plan to build in a guitar amp/guitar rack in the back. Pimp my ride styles.

If you go to an auto electrician they will be able to tell you how to wire it. It will probably be a matter of having half a dozen extra car batteries stashed somewhere to provide enough power so it doesn't drain too quickly. Like in show cars with massive stereos.

I have a 93" escort, and I can rock the shit out of it, lol. When I first bought the car, i put a new deck in it, with a mp3 input jack in the front of it. 1 day I was curious, so I ran my guitar through a cheap distortion box(on a battery), then straight into the mp3 input.
It worked fine. But It probably would destroy the speakers If it was too loud... But the difference is, I have an old escort, you have a Beemer, lol. Be careful.

alot of car head units now have 1/8" inputs for ipods. you can hook a guitar up to that no problem..

ive done it plenty of times.

I have a Pocket Rock-It and my gf's car stereo has an aux in...I haven't been able to try it yet (she wont let me!!!) but maybe i coulld do it like that...but would I be able to (put the amp speaker in the trunk) and with the radio controls, set it to play out of just the 'bass' and no other speakers? The bass would ultimatly be the amp speaker in the back. The actual amp would be the pocket rock-it. But what would I use to power the amplifier speaker?
Am I dreaming in the clouds? or is this possible?

p.s. Thanks for all the input so far!!

You should really take the most logical advice in this thread and not play guitar through your car speakers. It WILL ruin your speakers, full stop.
That Pocket Rock-It is pumping out 1/2w at 8 ohms, your sub would be a few hundred watts at 4 ohms. All you'd do is almost instantly destroy the Pocket Rock-It.

Use a power inverter and for a 'fuller' sound, install two guitar-designed speakers on either side of the car. Install the head somewhere where it's easily accessible and have it all discretely wired in. THAT would be cool
