Alright ladies, gents I have been searching all over the internet for car audio apparel. I have found some stuff but most companies dont ship to Canada. If anyone on this site knows of a place/store/person I can contact/purchase some quality car audio apparel that ships to Canada, it would be greatly appreciated if you could post up some info to help me out and we'll go from there. It doesn't have to have to necessarily be car audio, it could be car show/events apparel, even some engine performance apparel would be nice too. The ideal size I'm looking for is men's Large, and even better if these companies offer a women clothing line it wouldn't mind picking up a few things for a wife. I tried searching on the site but my computer kept giving me an error every time I tried to search, therefore I just posted the topic. If it has been discussed before, please redirect me to the topic or site it has been discussed on and the would be awesome.

What I'll do for the crossover's is play around with the knob, until i find the right balance with the front and rears playing there high and mid tones. Since I'm gonna be setting up the amps HP Filter on the HP setting. I understand how to set up the gain now with some basic math. Since I'm pretty good in math. So for my speakers I'd have to do: Fronts: √ 45 RMS X 4 ohm = √ 180 = 13.4V Rears : √ 85 RMS X 4 ohm = √ 340 = 18.4V Subs: 300 RMS X 2subs = √ 600RMS X 2 ohms = √ 1200 = 34.64V Alright, so now to adjust the gains for the fronts, rears, sub etc... Ex: I put my multimeter on the front {+}{-} speaker terminal and turn up the gain until it reaches 13.4V on the multimeter and voila its done, then double check both fronts and both rears for the same reading, then my gains are perfectly adjusted, right? I think i have everything down pat, let me know if i did something wrong.

So technically I'd be better off leaving the crossover setting in the middle, or just fine tuning it a bit when a song is playing, but will the difference be audible to my ears or do i have to be a pro to notice the adjustment difference. Now for the gain setting, do I turn the setting right down on the amp, then turn up the volume until it distorts, then turn the gain up slowly until it doesn't distort anymore. If this is how you do it, I'm OK from here, if not well, can you explain to me the simplest way to adjust it without costing me another set of speakers. And how to you adjust this with a multimeter, I have no problem using one, so if its simple enough let me know and ill give it a shot. As for the Filter settings, I still want these to pack out a "little" punch, I know I wont be getting any of that with 4X6's but the 6X9's maybe. Because sometimes I find my speakers can emit certain tones that my subs can't. I wanna be able to shut my subs off, and be able to still listen to good sounding music, not just highs or lows, kind of as if i would have no subs installed, is this possible to do or am I in la la land right now haha. Originally I was gonna set the amp up for highs and mids, and the subs for bass. If you think that's the best way to do it then you have me sold because I ain't no stereo expert.

So I was reading up the amps (Alpine MRP-F300) owners manual, everything seems to be alright, nothing to complicated here. What kind of had my confused was this whole Cross Over, Gain, HP filter stuff. Crossover: "Permits adjustment of crossover frequency, by rotating the knob to select any frequency between 50-400hz as the crossover point." What the hell is a crossover and what does it do. To me, this means leave it in the middle, so the fronts and rears play evenly? Gain: "Set the amplifiers gain knobs to the minimum (4v) position. Using a loud cassette or CD as a source, turn up the head units volume until it distorts, then reduce the volume by 1 set. You can then increase amplifier gain until the sound from the speakers becomes distorted." So technically you turn it up until the speakers distort, the adjust the gain up or down? What does it do exactly? HP Filter: Has three adjustments on the amp. LP,HP,OFF. HP: Highs and the Midrange. LP: Subwoofer Off: Full Range speakers. Are type S speakers full range? I thought they were for highs and midrange, or does it really matter? I'm running 2 10" subs, so technically i don't need these to put out some bass so id be better off setting them up as highs and mids with no bass right, and let the subs take care of that?

Thank you very much, your help is greatly appreciated, this clarifies a lot. Can I run the amp on only my fronts until I get my rears or should I get my rears and the amp at the same time to save myself a headache. EDIT: The Type S speakers are 3.6 ohm impedance, so i will run them at 4 ohms. How good is it? How easy is it to adjust and what kind of speakers are you running off it if you don't mind me asking. What size and whats your RMS rating on each. At this point, it will honestly depend on what kind of deal I get get on either. Since the cap is no longer in my budget I think I can afford the amp, but then again depending on how good that power pack is, from one of the posters comments, I might give it a shot for a good price. Because the amp price varies from 140-160+ shipping plus the cost of wires and the pack is something like 130-140+shipping, but the amp is something I can use anywhere, anytime, with no matter what kind of deck I'm using which to me makes more sense. Edit: You guys convinced me enough to buy the 4 channel so I did haha.

Ya for the wiring ill be running Stinger 4 gauge and I'll make up my mind on the distribution block then day of the installation lol. I'll branch off my existing remote wire and most likely run the same 400 series Monster Cable 4 channel amp RCA interconnects. As for the impedance, the amp has 4 slots up top for the rear decks, and 4 slots for the front. If I wire them at 2ohms I would one be using 4 slots instead of 8, two at the top and two at the bottom right? If so I completely understand now. By slots I mean, My link [+][-] [+][-] (Rear Deck, 4 slots or tabs) [+][-] [+][-] (Front Stage, 4 slots or tabs) I would only be using the first 4 if i were to wire at 2 ohms and all of them at 4 ohms. Would my speakers be able to handle 2 ohms, or am i better off doing them at 4 ohms to be safe??? And my deck has a max output of 45Wx4 will the amp be able to run off my deck? The amp puts out a minimum of 50W at 4 ohms? or am I right out of the ball park right now with this thought.

Sounds good, that's what ill be doing then. If I run this amp the Alpine MRP-F300, Amp How do I wire this whole thing up. From my understanding, this amp is going to wire up the same way as my single channel matching one, power wire, ground to chassis, remote wire and plug in all the speakers. That I know how to do, but i want to stay away from running to many wires, can I buy a distribution block, plug in my two 4 gauge power wires in one end, and make one 2 gauge or 0 gauge go out to my battery from the other end. As for my remote wire, do I have to run two separate wires or can I just branch off the other one to turn my amp on. What is the difference between wiring my speakers at 2ohm and 4 ohm, apart from the output power, which way do you connect your wires to make it different. my front are 45 RMS, and my rear will be 85 RMS that's a significant difference, if it puts out 75W in 2ohm and 50W in 4 ohm, that's higher then my 45 RMS in the fronts and lower then 85 RMS for my rears. I think im really missing the boat here can someone explain to me in depth how this works.

Thanks a lot for the reply, Ya if I were to get a 4 channel amp, I would match it with the MRP-F300. But you are completely right, as soon as I turn up my volume past say 10-13, they start to distort. As for the power pack, I was going to either extend the wires or make it accessible in some kind of way, I had thought about that. Wire soldering, and extending isn't a problem. I have plenty of room behind the dash worst case scenario to put it behind there. I'm just trying to keep this as easy as possible for myself and I also know that you get what you pay for just so were on the same page. As for the big three upgrade, I read up on it, and to be really honest, I really don't think im capable of doing such thing without f***ing everything right up, and well since this is my daily driver I cant really afford to mess things up, that's why i was thinking a cap, but my lights only dim when I really slam them to some Psyph Morrison, and a few other tracks. My volt gauge never even budges when I listen to some normal hip-hop, rock etc... So technically you think I don't need a cap, and it would be a useless upgrade, but if i do put one in, will i notice a significant difference? Or is it a one way ticket to a burnt alternator. A battery upgrade also is a great suggestion, thanks. As for the box, I bought a ported American Bass box, the TLE 210. I don't have time to build a box, and there isn't a hardware store in town here that sells MDF, so that's basically why I didn't build one. As for my rear deck speakers, I want some Type S 6X9's. Their 85W RMS, If I decide to get the power pack, will it have enough power to power these up properly, or will they sound distorted because of the lack of power going to them.

I would like to say Hi! to everyone, This is my first topic/post, but have been doing lots of reading over the past few months. Some systems I have seen on here have simply blown me away, and lets just say that my system well simply doesn't compare to some of your master pieces. If I were to build a system half as loud or with half the bass I would embarrass everyone here at home haha. Here's my system up until now. I currently drive a 2 door Pontiac Grand Am GT, and lets just say the stock system just straight up blew big ones. This winter I had the chance to purchase two 10" Alpine Type S subs(2 ohm, 300 RMS, 900 Peak) brand new in box for 40$, yes 40$ brand new!!! These are running off an Alpine MRP-M500 single channel amp, wired with Stinger 4 gauge power and ground wire and fuse holder, 16 gauge speaker wire and monster cable 400 series RCA interconnects. I went out and bought a new head unit, something simple, the Alpine IDA-X303, (16WX4, 45X4 Max) great deck for the price, I have had no problems with it what so ever . I also bought some Alpine Type S SPS 4X6 (45 RMS, 90 Peak) front speakers to upgrade from the stocks. Up until now everything's running, and sounding spectacular for me, but I want a little more power. Alright so these are my questions, I don't want to run an external amp to power my speakers, I wanted to possibly run the Alpine KTP-445 (45WX4) power pack. Its small and simple to install and has a decent price tag attached to it but my head units max output is 45WX4 which is the same as the power pack, will I be able to plug it into my head unit without any problems?? From my understanding I should be able to, but im just double checking. Also, will this power pack make my speakers louder and sound clearer, im pretty sure they will be but again just checking up for a second opinion. If I decide to install the power pack, from my understanding, I will need to upgrade my rear deck speakers, the paper stocks wont cut it so I was thinking of matching my fronts with my rears, I was gonna get some Alpine SPS 6X9 which are 85W RMS, 260 Peak. Will the head unit and the power pack have enough power to power these up? I'm really not sure on how this all works, I have an idea but nothing I would like to stand by my word for. I would also like to add a capacitor to my system, I was thinking a 1 farad stinger cap with a LED read out seems about right but then again if someone can suggest something better I'm open to all offers. Here are some links to some of the stuff to help you guys out, Head unit Power Pack 4X6 Speakers 6X9 Speakers Subwoofer Amplifier Capacitor I really hope someone can help me out. I know my whole system is Alpine, but we have one reputable store around here and they only sell Alpine and I personally think they make some good car audio equipment for a good price, figured I'd stick with one whole company. I'm not looking to go bigger, just something simple that sounds great. DJ BigC
