Sup everyone.. Im Brian.. I got a 07 Mazdaspeed 3 and looking into a system.. Im a newbie when it comes to audio.. but i want to learn and gotta start somewhere..

Currently got a Kenwood Headunit (KDC-X496 eXcelon).. I was looking into getting a 4 channel amp (Kicker 11DX400.4).. upgrading my front speakers (kicker ds68.2 6x8 45 watts rms).. and 10" sub (MTX RTS10-44)..

i'm trying to understand OHMs and i have somewhat figured it out.. im looking into using the amp for the 2 front speakers and bridge the other 2 for my sub..

is it better to have the amp put out little bit more power than the speaker rating or lower?

any recommendations for a sub and amp would be appreciated..


Precision Power PPi P900.4
Image Dynamics ID12D2 V.3
Ground Shaker Ported Box

I'll probably add the comps later if i feel the need to.. i'll be installing this all tomorrow.

Having more power than the sub's rating provides you with what we call overhead. That's the recommended way to go because you're less likely to cause damage to the sub from having the amp send a clipped signal due to overwork.

What is your sound goal? Sound Quality (SQ) or just plain loud (SPL)?

Hmm...Ktown you say? You didn't happen to sell an ID10 a couple months back, did you?

Most people learn better DIY by trial and error. At least it's worked out well for me. Just keep reading and asking questions.

that wasnt me.. is they system that im getting decent? i remember years back when i had my tiburon hooked up i liked it alot.. pioneer avic n1.. stock infinity 360 watt system.. with a 10" mtx sub.. cant remember the model.. but something like that would be nice without breaking the bank..

MTX used to be great, but I'm not too pleased with their new offerings. Better can be had for less these days.

I'd recommend looking at a different amp than that Kicker as well, same story. PPI makes a great small-form 4-channel (P900.4). Soundstream has a carbon copy of that in a better (IMO) casing (TN900.4). You can get either on onlinecarstereo.com for 200 or ask trumpet ; since he's an authorized dealer. For the sub, you would be pretty happy with either a SSA dcon or Dayton Audio HO and both are way underpriced for what you get.

As for the comps, those DS series IIRC are a refresh of the SS line. Nice comps, but so dang expensive. Especially considering you could go DLS Reference series for less. CDT, JBL MS, ID CTX, and Sundown all make respectable comps that would work just as well if not better for less.

not too many options when it comes down to 6x8.. : /

You can easily change those 6x8 to 6.5". Just need to trace out the 6x8 shape on some MDF and cut a baffle. Bam! Instant upgrade.

when it says:

4 ohms: 60 watts x 4 chan.
2 ohms: 120 watts x 4 chan.
Bridged, 4 ohms: 240 watts x 2 chan.

using 4ohms.. my 2 front speakers at 60watts and my sub bridged at 240.. right?

neo_styles
12-12-2012, 04:14 PM
Right. Make sure when looking for a sub, you look for a Dual 2 ohm or a Single 4 ohm to make sure it bridges properly. Most 4-channel amps can't support a 2 ohm bridged load.

Those PPI and SS amps I recommended carry a ton more power :fyi: At 200, I'd place it at the top of your list.

Just a warning on those Type R Components, the Tweeters are very harsh, you may not like them if you don't like blaring highs.

im more of a bass head and i like clarity.. i havent heard highs from other cars so i dont have much to compare with.. i looked at the infinity reference.. what do you recommend for around $150.. amp puts out 100rms..

neo_styles

For 150, ask mylows10 ; for his pricing on the Massive Audio CK6V. Those should perform much better than the Type R. New Infinity Reference isn't that bad, but the Kappa's leaps and bounds better. Only problem with the Kappas is finding somewhere to mount that giant tweeter.

I really like the look of the Massive Audio CK6X's, but haven't personally heard them. The only 150$ comps I've tried and really liked were the Image Dynamics CTX's, no experience with Infinity whatsoever really.

WTG, man.

What are you thinking of that ID? It's definitely weird listening to an SQ-oriented sub. I get a completely different impression on literally every single song I've ever listened to between this and a 12w3.

Also, once I get my ID10 in Brian's (Starr Mountain Sound) box, I'll let you hear the difference between it and the Ground Shaker you got in. Just want to make sure you're getting the full potential out of your system.

it's unbelievable.. i was disappointed at first. the sub sounded so weak and i wanted more thump to it. then the shop owner told me that it wasnt bridged! after it was done, amazing!

i wanted to install it myself but after i took a look at the crowded engine bay. i just went with the safer route.. i'm glad i did, because there was definitely some drilling and many hours of labor especially for the comps.. i'm guessing it took around 6 hours..

Yeah, I wouldn't consider the ID a thump kinda sub. It kinda just disappears in the rest of the system...at least it's getting there in mine, even at less than 200 watts to my ID10 sealed. I still need a proper enclosure and my front stage to install since I really can't register the midbass from my rear speakers while sitting up front. I'm borrowing a jig from someone at work, so hopefully I'll be done before Christmas with everything and she'll be ready to go.

Looks nice. That's a bigass box, though. Takes up almost your whole hatch
